The government has axed a scheme for upgrading energy efficiency in public sector buildings. The Public Sector Decarbonisation Scheme (PSDS) delivered more than £2.5bn in its first three phases for measures such as heat pumps, solar panels, insulation and double glazing, with further funding of nearly £1bn recently announced. But the Department for Energy Security and Net Zero (DESNZ) has told Building Design that the scheme has been dropped after the spending review, leaving uncertainty about how upgrades will be funded when the current phase expires in 2028. Source: UK Government/FlickrEd Miliband’s Department for Energy Security and Net Zero is responsible for the scheme The department said it would set out plans for the period after 2028 in due course. In a post on LinkedIn, Dave Welkin, director of sustainability at Gleeds, said he had waited for the release of the spending review with a “sense of trepidation” and was unable to find mention of public sector decarbonisation when Treasury documents were released. “I hoped because it was already committed in the Budget that its omission wasn’t ominous,” he wrote. Yesterday, he was told by Salix Finance, the non-departmental public body that delivers funding for the scheme, that it was no longer being funded. It comes after the withdrawal of funding for the Low Carbon Skills Fund (LCSF) in May. According to the government’s website, PSDS and LCSF were intended to support the reduction of emissions from public sector buildings by 75% by 2037, compared to a 2017 baseline. “Neither LCSF or PSDS were perfect by any means, but they did provide a vital source of funding for local authorities, hospitals, schools and many other public sector organisations to save energy, carbon and money,” Welkin said. “PSDS has helped replace failed heating systems in schools, keeping students warm. It’s replaced roofs on hospitals, helping patients recover from illness. It’s replaced windows in our prisons, improving security and stopping drugs getting behind bars.” However, responding to Welkin’s post, Steve Connolly, chief executive at Arriba Technologies, a low carbon heating and cooling firm, said that the scheme was being “mismanaged” with a small number of professional services firms “scooping up disproportionately large grants for their clients”. The fourth phase of the scheme was confirmed last September, with allocations confirmed only last month. This latest phase, which covers the financial years between 2025/26 and 2027/28, saw the distribution of £940m across the country. A DESNZ spokesperson said: “Our settlement is about investing in Britain’s renewal to create energy security, sprint to clean power by 2030, encourage investment, create jobs and bring down bills for good. “We will deliver £1bn in current allocations of the Public Sector Decarbonisation Scheme until 2028 and, through Great British Energy, have invested in new rooftop solar power and renewable schemes to lower energy bills for schools and hospitals across the UK. “We want to build on this progress by incentivising the public sector to decarbonise, so they can reap the benefits in lower bills and emissions, sharing best practice across government and exploring the use of repayable finance, where appropriate.” A government assessment of phase 3a and 3b projects identified a number of issues with the scheme, including delays and cost inflation, with more than a tenth being abandoned subsequent to grants being offered. Stakeholders interviewed for the report also identified “difficulties in obtaining skilled contractors and equipment”, especially air source heat pumps. The first come first served approach to awarding funding was also said to be “encouraging applicants to opt for more straightforward projects” and “potentially undermining the achievement of PSDS objective by restricting the opportunity for larger [and] more complex measures which may have delivered greater carbon reduction benefits”. But the consensus among stakeholders and industry representatives interviewed for the report was that the scheme was “currently key to sustaining the existing UK heat pump market” and that it was “seen as vital in enabling many public sector organisations to invest in heat decarbonisation”.

Construction input prices rose 0.2% in May, according to a new Associated Builders and Contractors (ABC) analysis of U.S. Bureau of Labor Statistics’ Producer Price Index data. Last month, nonresidential construction input prices reduced by 0.1%. Overall construction input prices are 1.3% higher than levels from a year ago, and nonresidential construction prices are 1.6% higher. Prices decreased in two of three major energy categories in April. Natural gas prices fell 18.7%, unprocessed energy materials were down 3.5%, and crude petroleum prices increased by 1.3%. Chart credit: Associated Builders and Contractors“Construction materials prices continued to increase at a faster-than-ideal pace in May,” said ABC Chief Economist Anirban Basu. “While input prices are up just 1.3% over the past year, that modest escalation is entirely due to price decreases during the second half of 2024. Costs have increased rapidly since the start of this year, with input prices rising at a 6% annualize...

Solar air heating is among the most cost-effective applications of solar thermal energy. These systems are used for space heating and preheating fresh air for ventilation, typically using glazed or unglazed perforated solar collectors. The collectors draw in outside air, heat it using solar energy, and then distribute it through ductwork to meet building heating and fresh air needs. In 2024, Canada led again the world for the at least seventh year in a row in solar air heating adoption. The four key suppliers – Trigo Energies, Conserval Engineering, Matrix Energy, and Aéronergie – reported a combined 26,203 m2 (282,046 ft2) of collector area sold last year. Several of these providers are optimistic about the growing demand. These findings come from the newly released Canadian Solar Thermal Market Survey 2024, commissioned by Natural Resources Canada. Canada is the global leader in solar air heating. The market is driven by a strong network of experienced system suppliers, optimized technologies, and a few small favorable funding programs – especially in the province of Quebec. Architects and developers are increasingly turning to these cost-effective, façade-integrated systems as a practical solution for reducing onsite natural gas consumption. Despite its cold climate, Canada benefits from strong solar potential with solar irradiance in many areas rivaling or even exceeding that of parts of Europe. This makes solar air heating not only viable, but especially valuable in buildings with high fresh air requirements including schools, hospitals, and offices. The projects highlighted in this article showcase the versatility and relevance of solar air heating across a range of building types, from new constructions to retrofits. Figure 1: Preheating air for industrial buildings: 2,750 m2 (29,600 ft2) of Calento SL solar air collectors cover all south-west and south-east facing facades of the FAB3R factory in Trois-Rivières, Quebec. The hourly unitary flow rate is set at 41 m3/m2 or 2.23 cfm/ft2 of collector area, at the lower range because only a limited number of intake fans was close enough to the solar façade to avoid long ventilation ductwork. Photo: Trigo Energies Quebec’s solar air heating boom: the Trigo Energies story Trigo Energies makes almost 90 per cent of its sales in Quebec. “We profit from great subsidies, as solar air systems are supported by several organizations in our province – the electricity utility Hydro Quebec, the gas utility Energir and the Ministry of Natural Resources,” explained Christian Vachon, Vice President Technologies and R&D at Trigo Energies. Trigo Energies currently has nine employees directly involved in planning, engineering and installing solar air heating systems and teams up with several partner contractors to install mostly retrofit projects. “A high degree of engineering is required to fit a solar heating system into an existing factory,” emphasized Vachon. “Knowledge about HVAC engineering is as important as experience with solar thermal and architecture.” One recent Trigo installation is at the FAB3R factory in Trois-Rivières. FAB3R specializes in manufacturing, repairing, and refurbishing large industrial equipment. Its air heating and ventilation system needed urgent renovation because of leakages and discomfort for the workers. “Due to many positive references he had from industries in the area, the owner of FAB3R contacted us,” explained Vachon. “The existence of subsidies helped the client to go for a retrofitting project including solar façade at once instead of fixing the problems one bit at a time.” Approximately 50 per cent of the investment costs for both the solar air heating and the renovation of the indoor ventilation system were covered by grants and subsidies. FAB3R profited from an Energir grant targeted at solar preheating, plus an investment subsidy from the Government of Quebec’s EcoPerformance Programme.   Blue or black, but always efficient: the advanced absorber coating In October 2024, the majority of the new 2,750 m² (29,600 ft2) solar façade at FAB3R began operation (see figure 1). According to Vachon, the system is expected to cover approximately 13 per cent of the factory’s annual heating demand, which is otherwise met by natural gas. Trigo Energies equipped the façade with its high-performance Calento SL collectors, featuring a notable innovation: a selective, low-emissivity coating that withstands outdoor conditions. Introduced by Trigo in 2019 and manufactured by Almeco Group from Italy, this advanced coating is engineered to maximize solar absorption while minimizing heat loss via infrared emission, enhancing the overall efficiency of the system. The high efficiency coating is now standard in Trigo’s air heating systems. According to the manufacturer, the improved collector design shows a 25 to 35 per cent increase in yield over the former generation of solar air collectors with black paint. Testing conducted at Queen’s University confirms this performance advantage. Researchers measured the performance of transpired solar air collectors both with and without a selective coating, mounted side-by-side on a south-facing vertical wall. The results showed that the collectors with the selective coating produced 1.3 to 1.5 times more energy than those without it. In 2024, the monitoring results were jointly published by Queen’s University and Canmat Energy in a paper titled Performance Comparison of a Transpired Air Solar Collector with Low-E Surface Coating. Selective coating, also used on other solar thermal technologies including glazed flat plate or vacuum tube collectors, has a distinctive blue color. Trigo customers can, however, choose between blue and black finishes. “By going from the normal blue selective coating to black selective coating, which Almeco is specially producing for Trigo, we lose about 1 per cent in solar efficiency,” explained Vachon.

Photo: Matrix Energy Matrix Energy: collaborating with architects and engineers in new builds The key target customer group of Matrix Energy are public buildings – mainly new construction. “Since the pandemic, schools are more conscious about fresh air, and solar preheating of the incoming fresh air has a positive impact over the entire school year,” noted Brian Wilkinson, President of Matrix Energy. Matrix Energy supplies systems across Canada, working with local partners to source and process the metal sheets used in their MatrixAir collectors. These metal sheets are perforated and then formed into architectural cladding profiles. The company exclusively offers unglazed, single-stage collectors, citing fire safety concerns associated with polymeric covers. “We have strong relationships with many architects and engineers who appreciate the simplicity and cost-effectiveness of transpired solar air heating systems,” said President Brian Wilkinson, describing the company’s sales approach. “Matrix handles system design and supplies the necessary materials, while installation is carried out by specialized cladding and HVAC contractors overseen by on-site architects and engineers,” Wilkinson added. Finding the right flow: the importance of unitary airflow rates One of the key design factors in solar air heating systems is the amount of air that passes through each square meter of the perforated metal absorber,  known as the unitary airflow rate. The principle is straightforward: higher airflow rates deliver more total heat to the building, while lower flow rates result in higher outlet air temperatures. Striking the right balance between air volume and temperature gain is essential for efficient system performance. For unglazed collectors mounted on building façades, typical hourly flow rates should range between 120 and 170 (m3/h/m2), or 6.6 to 9.4 cfm/ft2. However, Wilkinson suggests that an hourly airflow rate of around 130 m³/h/m² (7.2 cfm/ft2) offers the best cost-benefit balance for building owners. If the airflow is lower, the system will deliver higher air temperatures, but it would then need a much larger collector area to achieve the same air volume and optimum performance, he explained. It’s also crucial for the flow rate to overcome external wind pressure. As wind passes over the absorber, air flow through the collector’s perforations is reduced, resulting in heat losses to the environment. This effect becomes even more pronounced in taller buildings, where wind exposure is greater. To ensure the system performs well even in these conditions, higher hourly airflow rates typically between 150 and 170 m³/m² (8.3 to 9.4 cfm/ft2)  are necessary.

Photo: Conserval Engineering Solar air heating systems support LEED-certified building designs Solar air collectors are also well-suited for use in multi-unit residential buildings. A prime example is the Canary District in Toronto (see Figure 3), where single-stage SolarWall collectors from Conserval Engineering have been installed on several MURBs to clad the mechanical penthouses. “These penthouses are an ideal location for our air heating collectors, as they contain the make-up air units that supply corridor ventilation throughout the building,” explained Victoria Hollick, Vice President of Conserval Engineering. “The walls are typically finished with metal façades, which can be seamlessly replaced with a SolarWall system – maintaining the architectural language without disruption.” To date, nine solar air heating systems have been commissioned in the Canary District, covering a total collector area of over 1,000 m² (10,764 ft2). “Our customers have many motivations to integrate SolarWall technology into their new construction or retrofit projects, either carbon reduction, ESG, or green building certification targets,” explained Hollick. The use of solar air collectors in the Canary District was proposed by architects from the Danish firm Cobe. The black-colored SolarWall system preheats incoming air before it is distributed to the building’s corridors and common areas, reducing reliance on natural gas heating and supporting the pursuit of LEED Gold certification. Hollick estimates the amount of gas saved between 10 to 20 per cent of the total heating load for the corridor ventilation of the multi-unit residential buildings. Additional energy-saving strategies include a 50/50 window-to-wall ratio with high-performance glazing, green roofs, high-efficiency mechanical systems, LED lighting, and Energy Star-certified appliances. The ideal orientation for a SolarWall system is due south. However, the systems can be built at any orientation up to 90° east and west, explained Hollick. A SolarWall at 90° would have approximately 60 per cent of the energy production of the same area facing south.Canada’s expertise in solar air heating continues to set a global benchmark, driven by supporting R&D, by innovative technologies, strategic partnerships, and a growing portfolio of high-impact projects. With strong policy support and proven performance, solar air heating is poised to play a key role in the country’s energy-efficient building future.

President Donald Trump signed an executive order Friday that revises and rolls back cybersecurity policies set in place by his Democratic predecessors, Barack Obama and Joe Biden. In a White House fact sheet, the administration claims that Biden’s Executive Order 14144 — signed days before the end of his presidency — was an attempt “to sneak problematic and distracting issues into cybersecurity policy.” Among other things, Biden’s order encouraged agencies to “consider accepting digital identity documents” when public benefit programs require ID. Trump struck that part of the order, with the White House now saying this approach risks “widespread abuse by enabling illegal immigrants to improperly access public benefits.” However, Mark Montgomery, senior director of the Foundation for Defense of Democracies’ Center on Cyber and Technology Innovation, told Politico that “the fixation on revoking digital ID mandates is prioritizing questionable immigration benefits over proven cybersecurity benefits.”  On AI, Trump removed Biden’s requirements around testing the use of AI to defend energy infrastructure, funding federal research programs around AI security, and directing the Pentagon to “use AI models for cyber security.” The White House describes its moves on AI as refocusing AI cybersecurity strategy “towards identifying and managing vulnerabilities, rather than censorship.” (Trump’s Silicon Valley allies have complained repeatedly about the threat of AI “censorship.”) Trump’s order also removed requirements that agencies start using quantum-resistant encryption “as soon as practicable.” And it removed requirements that federal contractors attest to the security of their software — the White House describes those requirements as “unproven and burdensome software accounting processes that prioritized compliance checklists over genuine security investments.” Techcrunch event Save $200+ on your TechCrunch All Stage pass Build smarter.

Boston, MA | July 15 REGISTER NOW Going back even further, Trump’s executive order repeals Obama’s policies around sanctions for cybersecurity attacks on the United States; those sanctions can now only be applied to “foreign malicious actors.” The White House says this will will prevent “misuse against domestic political opponents” and clarify that “sanctions do not apply to election-related activities.”

This audio is auto-generated. Please let us know if you have feedback. President Donald Trump signed an executive order (EO) Friday that scratched or revised several of his Democratic predecessors’ major cybersecurity initiatives. “Just days before President Trump took office, the Biden Administration attempted to sneak problematic and distracting issues into cybersecurity policy,” the White House said in a fact sheet about Trump’s new directive, referring to projects that Biden launched with his Jan. 15 executive order. Trump’s new EO eliminates those projects, which would have required software vendors to prove their compliance with new federal security standards, prioritized research and testing of artificial intelligence for cyber defense and accelerated the rollout of encryption that withstands the future code-cracking powers of quantum computers. “President Trump has made it clear that this Administration will do what it takes to make America cyber secure,” the White House said in its fact sheet, “including focusing relentlessly on technical and organizational professionalism to improve the security and resilience of the nation’s information systems and networks.” Major cyber regulation shift Trump’s elimination of Biden’s software security requirements for federal contractors represents a significant government reversal on cyber regulation. Following years of major cyberattacks linked to insecure software, the Biden administration sought to use federal procurement power to improve the software industry’s practices. That effort began with Biden’s 2021 cyber order and gained strength in 2024, and then Biden officials tried to add teeth to the initiative before leaving office in January. But as it eliminated that project on Friday, the Trump administration castigated Biden’s efforts as “imposing unproven and burdensome software accounting processes that prioritized compliance checklists over genuine security investments.” Trump’s order eliminates provisions from Biden’s directive that would have required federal contractors to submit “secure software development attestations,” along with technical data to back up those attestations. Also now eradicated are provisions that would have required the Cybersecurity and Infrastructure Security Agency to verify vendors’ attestations, required the Office of the National Cyber Director to publish the results of those reviews and encouraged ONCD to refer companies whose attestations fail a review to the Justice Department “for action as appropriate.” Trump’s order leaves in place a National Institute of Standards and Technology collaboration with industry to update NIST’s Software Software Development Framework, but it eliminates parts of Biden’s order that would have incorporated those SSDF updates into security requirements for federal vendors. In a related move, Trump eliminated provisions of his predecessor’s order that would have required NIST to “issue guidance identifying minimum cybersecurity practices” (based on a review of globally accepted standards) and required federal contractors to follow those practices. AI security cut Trump also took an axe to Biden requirements related to AI and its ability to help repel cyberattacks. He scrapped a Biden initiative to test AI’s power to “enhance cyber defense of critical infrastructure in the energy sector,” as well as one that would have directed federal research programs to prioritize topics like the security of AI-powered coding and “methods for designing secure AI systems.” The EO also killed a provision would have required the Pentagon to “use advanced AI models for cyber defense.” On quantum computing, Trump’s directive significantly pares back Biden’s attempts to accelerate the government’s adoption of post-quantum cryptography. Biden told agencies to start using quantum-resistant encryption “as soon as practicable” and to start requiring vendors to use it when technologically possible. Trump eliminated those requirements, leaving only a Biden requirement that CISA maintain “a list of product categories in which products that support post-quantum cryptography … are widely available.” Trump also eliminated instructions for the departments of State and Commerce to encourage key foreign allies and overseas industries to adopt NIST’s PQC algorithms. The EO dropped many other provisions of Biden’s January directive, including one requiring agencies to start testing phishing-resistant authentication technologies, one requiring NIST to advise other agencies on internet routing security and one requiring agencies to use strong email encryption. Trump also cut language directing the Office of Management and Budget to advise agencies on addressing risks related to IT vendor concentration. In his January order, Biden ordered agencies to explore and encourage the use of digital identity documents to prevent fraud, including in public benefits programs. Trump eliminated those initiatives, calling them “inappropriate.”  Trump also tweaked the language of Obama-era sanctions authorities targeting people involved in cyberattacks on the U.S., specifying that the Treasury Department can only sanction foreigners for these activities. The White House said Trump’s change would prevent the power’s “misuse against domestic political opponents.” Amid the whirlwind of changes, Trump left one major Biden-era cyber program intact: a Federal Communications Commission project, modeled on the Energy Star program, that will apply government seals of approval to technology products that undergo security testing by federally accredited labs. Trump preserved the language in Biden’s order that requires companies selling internet-of-things devices to the federal government to go through the FCC program by January 2027.

IT Pros ‘Extremely Worried’ About Shadow AI: Report By John P. Mello Jr. June 4, 2025 5:00 AM PT ADVERTISEMENT Enterprise IT Lead Generation Services Fuel Your Pipeline. Close More Deals.

Shadow AI — the use of AI tools under the radar of IT departments — has information technology directors and executives worried, according to a report released Tuesday. The report, based on a survey of 200 IT directors and executives at U.S. enterprise organizations of 1,000 employees or more, found nearly half the IT pros (46%) were “extremely worried” about shadow AI, and almost all of them (90%) were concerned about it from a privacy and security viewpoint. “As our survey found, shadow AI is resulting in palpable, concerning outcomes, with nearly 80% of IT leaders saying it has resulted in negative incidents such as sensitive data leakage to Gen AI tools, false or inaccurate results, and legal risks of using copyrighted information,” said Krishna Subramanian, co-founder of Campbell, Calif.-based Komprise, the unstructured data management company that produced the report. “Alarmingly, 13% say that shadow AI has caused financial or reputational harm to their organizations,” she told TechNewsWorld. Subramanian added that shadow AI poses a much greater problem than shadow IT, which primarily focuses on departmental power users purchasing cloud instances or SaaS tools without obtaining IT approval. “Now we’ve got an unlimited number of employees using tools like ChatGPT or Claude AI to get work done, but not understanding the potential risk they are putting their organizations at by inadvertently submitting company secrets or customer data into the chat prompt,” she explained. “The data risk is large and growing in still unforeseen ways because of the pace of AI development and adoption and the fact that there is a lot we don’t know about how AI works,” she continued. “It is becoming more humanistic all the time and capable of making decisions independently.” Shadow AI Introduces Security Blind Spots Shadow AI is the next step after shadow IT and is a growing risk, noted James McQuiggan, security awareness advocate at KnowBe4, a security awareness training provider in Clearwater, Fla. “Users use AI tools for content, images, or applications and to process sensitive data or company information without proper security checks,” he told TechNewsWorld. “Most organizations will have privacy, compliance, and data protection policies, and shadow AI introduces blind spots in the organization’s data loss prevention.” “The biggest risk with shadow AI is that the AI application has not passed through a security analysis as approved AI tools may have been,” explained Melissa Ruzzi, director of AI at AppOmni, a SaaS security management software company, in San Mateo, Calif. “Some AI applications may be training models using your data, may not adhere to relevant regulations that your company is required to follow, and may not even have the data storage security level you deem necessary to keep your data from being exposed,” she told TechNewsWorld. “Those risks are blind spots of potential security vulnerabilities in shadow AI.” Krishna Vishnubhotla, vice president of product strategy at Zimperium, a mobile security company based in Dallas, noted that shadow AI extends beyond unapproved applications and involves embedded AI components that can process and disseminate sensitive data in unpredictable ways. “Unlike traditional shadow IT, which may be limited to unauthorized software or hardware, shadow AI can run on employee mobile devices outside the organization’s perimeter and control,” he told TechNewsWorld. “This creates new security and compliance risks that are harder to track and mitigate.” Vishnubhotla added that the financial impact of shadow AI varies, but unauthorized AI tools can lead to significant regulatory fines, data breaches, and loss of intellectual property. “Depending on the scale of the agency and the sensitivity of the data exposed, the costs could range from millions to potentially billions in damages due to compliance violations, remediation efforts, and reputational harm,” he said. “Federal agencies handling vast amounts of sensitive or classified information, financial institutions, and health care organizations are particularly vulnerable,” he said. “These sectors collect and analyze vast amounts of high-value data, making AI tools attractive. But without proper vetting, these tools could be easily exploited.” Shadow AI Everywhere and Easy To Use Nicole Carignan, SVP for security and AI strategy at Darktrace, a global cybersecurity AI company, predicts an explosion of tools that utilize AI and generative AI within enterprises and on devices used by employees. “In addition to managing AI tools that are built in-house, security teams will see a surge in the volume of existing tools that have new AI features and capabilities embedded, as well as a rise in shadow AI,” she told TechNewsWorld. “If the surge remains unchecked, this raises serious questions and concerns about data loss prevention, as well as compliance concerns as new regulations start to take effect.” “That will drive an increasing need for AI asset discovery — the ability for companies to identify and track the use of AI systems throughout the enterprise,” she said. “It is imperative that CIOs and CISOs dig deep into new AI security solutions, asking comprehensive questions about data access and visibility.” Shadow AI has become so rampant because it is everywhere and easy to access through free tools, maintained Komprise’s Subramanian. “All you need is a web browser,” she said. “Enterprise users can inadvertently share company code snippets or corporate data when using these Gen AI tools, which could create data leakage.” “These tools are growing and changing exponentially,” she continued. “It’s really hard to keep up. As the IT leader, how do you track this and determine the risk? Managers might be looking the other way because their teams are getting more done. You may need fewer contractors and full-time employees. But I think the risk of the tools is not well understood.” “The low, or in some cases non-existent, learning curve associated with using Gen AI services has led to rapid adoption, regardless of prior experience with these services,” added Satyam Sinha, CEO and co-founder of Acuvity, a provider of runtime Gen AI security and governance solutions, in Sunnyvale, Calif. “Whereas shadow IT focused on addressing a specific challenge for particular employees or departments, shadow AI addresses multiple challenges for multiple employees and departments. Hence, the greater appeal,” he said. “The abundance and rapid development of Gen AI services also means employees can find the right solution [instantly]. Of course, all these traits have direct security implications.” Banning AI Tools Backfires To support innovation while minimizing the threat of shadow AI, enterprises must take a three-pronged approach, asserted Kris Bondi, CEO and co-founder of Mimoto, a threat detection and response company in San Francisco. They must educate employees on the dangers of unsupported, unmonitored AI tools, create company protocols for what is not acceptable use of unauthorized AI tools, and, most importantly, provide AI tools that are sanctioned. “Explaining why one tool is sanctioned and another isn’t greatly increases compliance,” she told TechNewsWorld. “It does not work for a company to have a zero-use mandate. In fact, this results in an increase in stealth use of shadow AI.” In the very near future, more and more applications will be leveraging AI in different forms, so the reality of shadow AI will be present more than ever, added AppOmni’s Ruzzi. “The best strategy here is employee training and AI usage monitoring,” she said. “It will become crucial to have in place a powerful SaaS security tool that can go beyond detecting direct AI usage of chatbots to detect AI usage connected to other applications,” she continued, “allowing for early discovery, proper risk assessment, and containment to minimize possible negative consequences.” “Shadow AI is just the beginning,” KnowBe4’s McQuiggan added. “As more teams use AI, the risks grow.” He recommended that companies start small, identify what’s being used, and build from there. They should also get legal, HR, and compliance involved. “Make AI governance part of your broader security program,” he said. “The sooner you start, the better you can manage what comes next.” John P.

From lifelike avatars to automated fan interactions, AI is remaking digital modeling. But can tech ... More scale intimacy — or will it erode the human spark behind the screen?getty The AI boom has been defined by unprecedented innovation across nearly every sector. From improving flight punctuality through AI-powered scheduling to detecting early markers of Alzheimer’s disease, AI is modifying how we live and work. And the advertising world isn’t left out. In March of this year, OpenAI’s GPT-4o sent the internet into a frenzy with its ability to generate Studio Ghibli-style images. The model produces realistic, emotionally nuanced visuals from a series of prompts — a feat that has led some to predict the demise of visual arts as we know them. While such conclusions may be premature, there’s growing belief among industry players that AI could transform how digital model agencies operate. That belief isn’t limited to one startup. A new class of AI-powered agencies — including FanPro, Lalaland.ai, Deep Agency andThe Diigitals — is testing whether modeling can be automated without losing its creative edge. Some use AI to generate lifelike avatars. Others offer virtual photo studios, CRM — customer relationship management — integrations, or creator monetization tools. Together, they reflect a big shift in how digital modeling agencies think about labor, revenue and scale. FanPro — founded by Tyron Humphris in 2023 to help digital model agencies scale efficiently — offers a striking case study. Fully self-funded, Humphris said in an interview that the company reached $1 million in revenue within its first 90 days and crossed eight figures by 2024, all while maintaining a lean team by automating nearly every process. As Humphris noted, “the companies that will lead this next decade won’t just be the ones with the best marketing or biggest budgets. They’ll be the ones who use AI, automation and systems thinking to scale with precision, all while staying lean and agile.” That explains the big bet that startups like FanPro are making — but how far can it really go? And why should digital model agencies care in the first place? Automation In Digital Model Agencies To understand how automation works in the digital modeling industry — a fast-rising corner of the creator economy — it helps to understand what it’s replacing. A typical digital model agency juggles five or more monetization platforms per creator — from OnlyFans and Fansly to TikTok and Instagram. But behind every viral post is a grind of scheduling, analytics, upselling, customer support and retention. The average agency may need 10 to 15 contractors to manage a roster of just a few high-performing creators. These agencies oversee a complex cycle: content creation, onboarding, audience engagement and sales funnel optimization, usually across several monetization platforms. According to Humphris, there’s often a misconception that running a digital model agency is just about posting pretty pictures. But in reality, he noted, it’s more. “It’s CRM, data science and psychology all wrapped in one. If AI can streamline even half of that, it’s a game-changer.” That claim reflects a growing pain point in the creator economy, where agencies swim in an ocean of tools in an attempt to monetize attention for creators while simultaneously managing marketing, sales and customer support. For context, a 2024 Clevertouch Consulting study revealed that 54% of marketers use more than 50 tools to manage operations — many stitched together with Zapier or manual workarounds. Tyron Humphris, founder of FanProFanPro But, according to Humphris, “no matter how strong your offer is, if you don’t have systems, processes and accountability built into the business, it’s going to collapse under pressure.” And that’s where AI steps in. Beyond handling routine tasks, large language models and automation stacks now allow agencies to scale operations while staying lean. With minimal human input, agencies can schedule posts, auto-respond to DMs, upsell subscriptions, track social analytics and manage retention flows. What once required a full team of marketers, virtual assistants and sales reps can now be executed by a few well-trained AI agents. FanPro claims that over 90% of its operations — from dynamic pricing to fan interactions — are now handled by automation. Likewise, Deep Agency allows creators to generate professional-grade photo shoots without booking a studio or hiring staff and Lalaland.ai helps fashion brands generate AI avatars to reduce production costs and increase diversity in representation. A Necessary Human Touch Still, not everyone is convinced that AI can capture the nuance of digital intimacy. Some experts have raised concerns that hyper automation in creator-driven industries could flatten human expression into predictable engagement patterns, risking long-term user loyalty. A 2024 ContentGrip study of 1,000 consumers found 80% of respondents would likely switch brands that rely heavily on AI-generated emails, citing a loss of authenticity. Nearly half said such messages made them feel “less connected” to the brand. Humphris doesn’t disagree. “AI can do a lot, but it needs to be paired with someone who understands psychology,” he said. “We didn’t scale because we had the best tech. We scaled because we understood human behavior and built systems that respected it.” Humphris’ sentiment isn’t a mere anecdote but one rooted in research. For example, a recent study by Northeastern University showed that AI influencers often reduce brand trust — especially when users aren’t aware the content is AI-generated. The implication is clear: over-automating the wrong parts of human interaction can backfire. Automation doesn’t — and shouldn’t — mean that human input becomes obsolete. Rather, as many industry experts have noted, it will enhance efficiency but not replace empathy. While AI can process data at speed and generate alluring visuals, it cannot replicate human creativity or emotional intelligence. Neither does AI know the psychology of human behavior like humans do, a trait Humphris credits for their almost-instant success. What’s Working — And What’s Not Lalaland.ai and The Diigitals have earned praise for enhancing inclusivity, enabling brands to feature underrepresented body types, skin tones and styles. Meanwhile, FanPro focuses on building AI “growth engines” for agencies — full-stack systems that combine monetization tools, CRM and content flows. But not all reactions have been positive. In November 2024, fashion brand Mango faced backlash for its use of AI-generated models, which critics called “false advertising” and “a threat to real jobs.” The New York Post covered the fallout in detail, highlighting how ethical lines are still being drawn. As brands look to balance cost savings with authenticity, some have begun labeling AI-generated content more clearly — or embedding human oversight into workflows, rather than removing it. Despite offering an automation stack, FanPro itself wasn’t an immediate adopter of automation in its processes. But, as Humphris noted, embracing AI made all the difference for the company. “If we had adopted AI and automation earlier, we would’ve hit 8 figures much faster and with far less stress,” he noted. Automation In The New Era FanPro is a great example of how AI integration, when done the right way, could be a profitable venture for digital model agencies. Whether or not the company’s model becomes the blueprint for AI-first digital agencies, it’s clear that there’s a big shift in the creator economy, where automation isn’t only viewed as a time-saver, but also as a foundational pillar for businesses. As digital model agencies lean further into an AI-centric future, the bigger task is remembering what not to automate — the spark of human connection that built the industry in the first place. “In this new era of automation,” Humphris said, “the smartest agencies won’t just ask what AI can do. They’ll ask what it shouldn’t.”

The housing catalogue includes 50 low-rise home designs, including for garden suites, duplexes, four-plexes and six-plexes. Each design was developed by local architecture and engineering teams with the intent of aligning with regional building codes, planning rules, climate zones, construction methods and materials. TEXT John Lorinc RENDERINGS Office In Search Of During the spring election, the Liberals leaned into messaging that evoked a historic moment from the late 1940s, when Ottawa succeeded in confronting a severe housing crisis.  “We used to build things in this country,” begins Prime Minister Mark Carney in a nostalgic ad filled with archival images of streets lined with brand new post-World War II “strawberry box” bungalows, built for returning Canadian soldiers and their young families.  The video also includes montages from the now-iconic design “catalogues,” published by Canada Mortgage and Housing Corporation (CMHC). These supplied floor plans and unlocked cheap mortgages for tens of thousands of simple suburban houses found in communities across the country. “The government built prefabricated homes that were easy to assemble and inexpensive,” Carney said in the voice-over. “And those homes are still here.”  Over the past year, CMHC has initiated a 21st century re-do of that design catalogue, and the first tranche of 50 plans—for garden suites, duplexes, four-plexes and six-plexes—went live in early March. A second tranche, with plans for small apartments, is under development.  Unlike the postwar versions, these focus on infill sites, not green fields. One of CMHC’s goals is to promote so-called gentle density to residential properties with easily constructed plans that reflect regional variations, local zoning and building-code regulations, accessibility features and low-carbon design. As with those postwar catalogues, CMHC’s other goal was to tamp down on soft costs for homeowners or small builders looking to develop these kinds of housing by providing no-cost designs that were effectively permit sets. The early reviews are generally positive. “I find the design really very compelling in a kind of understated way,” says SvN principal Sam Dufaux. By making available vetted plans that can be either pre-approved or approved as of right, CMHC will remove some of the friction that impedes this scale of housing. “One of the elements of the housing crisis has to do with how do we approve these kinds of projects,” Dufaux adds. “I’m hoping it is a bit of a new beginning.” Yet other observers offer cautions about the extent to which the CMHC program can blunt the housing crisis. “It’s a small piece and a positive one,” says missing middle advocate and economist Mike Moffatt, who is executive in residence at the Smart Prosperity Institute and an assistant professor at Western’s Ivey Business School. “But [it’s] one that probably captures a disproportionate amount of attention because it’s something people can visualize in a way that they can’t with an apartment tax credit.” This kind of new-build infill is unlikely to provide much in the way of affordable or deeply affordable housing, adds Carolyn Whitzman, housing and social policy researcher, and author of Home Truths: Fixing Canada’s Housing Crisis (UBC Press, 2024). She estimates Canada needs about three million new dwellings that can be rented for $1,000 per month or less. The policies that will enable new housing at that scale, she says, involve financing subsidies, publicly owned land, and construction innovation, e.g., prefabricated or factory-built components, as well as “consistent and permissive zoning and consistent and permissive building codes.”  Indeed, the make-or-break question hovering over CMHC’s design catalogue is whether municipalities will green-light these plans or simply find new ways to hold up approvals.   An axonometric of a rowhouse development from the Housing Catalogue, designed for Alberta. A team effort Janna Levitt, partner at LGA Architectural Partners, says that when CMHC issued an RFP for the design catalogue, her firm decided to pitch a team of architects and peer reviewers from across Canada, with LGA serving as project manager. After they were selected, Levitt says they had to quickly clarify a key detail, which was the assumption that the program could deliver pre-approved, permit-ready plans absent a piece of property to build on. “Even in 1947,” she says, “it wasn’t a permit set until you had a site.” LGA’s team and CMHC agreed to expand the scope of the assignment so that the finished product wasn’t just a catalogue of plans but also included details about local regulations and typical lot sizes. Re-Housing co-founder Michael Piper, an associate professor at U of T’s John H. Daniels Faculty of Architecture, Landscape, and Design, came on board to carry out research on similar programs, and found initiatives in places like Georgia, Indiana and Texas. “I have not found any that moved forward,” he says. “Canada’s national design catalogue is pretty novel in that regard, which is exciting.” The noteworthy exceptions are California, which has made significant advances in recent years in pre-approving ADUs across the state, and British Columbia, which last fall released its own standardized design catalogue.  He also carried out a scan of land use and zoning rules in Ontario for 15 to 20 municipalities. “We looked to see [what] their zoning permitted and what the rules were, and as you might expect, they’re all over the place,” he says. “Hence the challenge with the standardized design.” At present, high-level overviews for the 50 designs are available, including basic floor plans, 3D axonometrics, and building dimensions. Full architectural design packages are expected to be released later this year. Levitt says the architects on the team set out to come up with designs that used wood frame construction, had no basements (to save on cost and reduce embodied carbon), and drew on vernacular architectural styles. They researched representative lot sizes in the various regions, and configured designs to suit small, medium and large properties. Some versions have accessibility features—CMHC’s remit included both accessible units and aging-in-place as objectives—or can be adapted later on.  As for climate and energy efficiency considerations, the recommended materials include low-carbon components and cladding. The designs do reflect geographical variations, but Levitt says there’s only so much her team could do in terms of energy modelling. “How do you do heat energy calculations when you don’t have a site? You don’t have north, south, east, west [orientations] and you don’t have what zone are you in. In B.C. and Ontario, there are seven climatic regions. There was a lot of working through those kinds of very practical requirements, which were very complicated and actually fed into the design work quite significantly.” As Levitt adds, “in 1947, there were no heat loss models because the world wasn’t like that.” LGA provided the architects on the team with templates for interior elements, such as bathrooms, as well as standards for features such as bedroom sizes, dining areas, storage sufficient to hold strollers, and access to outdoor space, either at grade or via a balcony. “We gathered together these ideas about the quality of life that we wanted baked into each of the designs, so that [they] expressed a really good quality of life—modest but good quality,” she says. “It’s not about the finishes. People had to be able to live there and live there well.” “This isn’t a boutique home solution,” Whitzman says. “This is a cheap and mass-produced solution. And compared to other cheap and mass-produced solutions, whether they be condos or suburban subdivisions, [the catalogue designs] look fine to my untrained eye.” A selection of Housing Catalogue designs for the Atlantic region. Will it succeed?  With the plans now public, the other important variables, besides their conformity with local bylaws, have to do with cost and visibility to potential users, including homeowners, contractors and developers specializing in smaller-scale projects.  On the costing side, N. Barry Lyons Consultants (NBLC) has been retained by CMHC to develop models to accompany the design catalogue, but those figures have yet to be released. While pricing is inevitably dynamic, the calculus behind the entire exercise turns on whether the savings on design outlays and the use of prefabricated components will make such small-scale projects pencil, particularly at a time when there are live concerns about tariffs, skilled labour shortages, and supply chain interruptions on building materials.  Finally, there’s the horse-to-water problem. While the design catalogue has received a reasonable amount of media attention since it launched, does CMHC need to find ways to market it more aggressively? “From my experience,” says Levitt, “they are extremely proactive, and have assembled a kind of dream team with a huge range of experience and expertise. They are doing very concerted and deep work with municipalities across the country.” Proper promotion, observes Moffatt, “is going to be important in particular, just for political reasons. The prime minister has made a lot of bold promises about [adding] 500,000 homes.” Carney’s pledge to get Canada back into building will take time to ramp up, he adds. “I do think the federal government needs to visibly show progress, and if they can’t point to a [new] building across the road, they could at least [say], `We’ve got this design catalogue. Here’s how it works. We’ve already got so many builders and developers looking at this.’”  While it’s far too soon to draw conclusions about the success of this ambitious program, Levitt is well aware of the long and rich legacy of the predecessor CMHC catalogues from the late 40s and the 1950s, all of which gave many young Canadian architects their earliest commissions and then left an enduring aesthetic on countless communities across Canada.   She hopes the updated 21st-century catalogue—fitted out as it is for 21st-century concerns about carbon, resilience and urban density—will acquire a similar cachet.  “These are architecturally designed houses for a group of people across the country who will have never lived in an architecturally designed house,” she muses. “I would love it if, 80 years from now, the consistent feedback [from occupants] was that they were able to live generously and well in those houses, and that everything was where it should be.” ARCHITECTURE FIRM COLLABORATORS Michael Green Architecture, Dub Architects, 5468796 Architecture Inc, Oxbow Architecture, LGA Architectural Partners, KANVA Architecture, Abbott Brown Architects, Taylor Architecture Group  As appeared in the June 2025 issue of Canadian Architect magazine  The post A housing design catalogue for the 21st century appeared first on Canadian Architect.

Smart TVs, take note Breaking down why Apple TVs are privacy advocates’ go-to streaming device Using the Apple TV app or an Apple account means giving Apple more data, though. Scharon Harding – Jun 1, 2025 7:35 am | 22 Credit: Aurich Lawson | Getty Images Credit: Aurich Lawson | Getty Images Story text Size Small Standard Large Width * Standard Wide Links Standard Orange * Subscribers only   Learn more Every time I write an article about the escalating advertising and tracking on today's TVs, someone brings up Apple TV boxes. Among smart TVs, streaming sticks, and other streaming devices, Apple TVs are largely viewed as a safe haven. "Just disconnect your TV from the Internet and use an Apple TV box." That's the common guidance you'll hear from Ars readers for those seeking the joys of streaming without giving up too much privacy. Based on our research and the experts we've consulted, that advice is pretty solid, as Apple TVs offer significantly more privacy than other streaming hardware providers. But how private are Apple TV boxes, really? Apple TVs don't use automatic content recognition (ACR, a user-tracking technology leveraged by nearly all smart TVs and streaming devices), but could that change? And what about the software that Apple TV users do use—could those apps provide information about you to advertisers or Apple? In this article, we'll delve into what makes the Apple TV's privacy stand out and examine whether users should expect the limited ads and enhanced privacy to last forever. Apple TV boxes limit tracking out of the box One of the simplest ways Apple TVs ensure better privacy is through their setup process, during which you can disable Siri, location tracking, and sending analytics data to Apple. During setup, users also receive several opportunities to review Apple's data and privacy policies. Also off by default is the boxes' ability to send voice input data to Apple. Most other streaming devices require users to navigate through pages of settings to disable similar tracking capabilities, which most people are unlikely to do. Apple’s approach creates a line of defense against snooping, even for those unaware of how invasive smart devices can be. Apple TVs running tvOS 14.5 and later also make third-party app tracking more difficult by requiring such apps to request permission before they can track users. "If you choose Ask App Not to Track, the app developer can’t access the system advertising identifier (IDFA), which is often used to track," Apple says. "The app is also not permitted to track your activity using other information that identifies you or your device, like your email address." Users can access the Apple TV settings and disable the ability of third-party apps to ask permission for tracking. However, Apple could further enhance privacy by enabling this setting by default. The Apple TV also lets users control which apps can access the set-top box's Bluetooth functionality, photos, music, and HomeKit data (if applicable), and the remote's microphone. "Apple’s primary business model isn’t dependent on selling targeted ads, so it has somewhat less incentive to harvest and monetize incredible amounts of your data," said RJ Cross, director of the consumer privacy program at the Public Interest Research Group (PIRG). "I personally trust them more with my data than other tech companies." What if you share analytics data? If you allow your Apple TV to share analytics data with Apple or app developers, that data won't be personally identifiable, Apple says. Any collected personal data is "not logged at all, removed from reports before they’re sent to Apple, or protected by techniques, such as differential privacy," Apple says. Differential privacy, which injects noise into collected data, is one of the most common methods used for anonymizing data. In support documentation (PDF), Apple details its use of differential privacy: The first step we take is to privatize the information using local differential privacy on the user’s device. The purpose of privatization is to assure that Apple’s servers don't receive clear data. Device identifiers are removed from the data, and it is transmitted to Apple over an encrypted channel. The Apple analysis system ingests the differentially private contributions, dropping IP addresses and other metadata. The final stage is aggregation, where the privatized records are processed to compute the relevant statistics, and the aggregate statistics are then shared with relevant Apple teams. Both the ingestion and aggregation stages are performed in a restricted access environment so even the privatized data isn’t broadly accessible to Apple employees. What if you use an Apple account with your Apple TV? Another factor to consider is Apple's privacy policy regarding Apple accounts, formerly Apple IDs. Apple support documentation says you "need" an Apple account to use an Apple TV, but you can use the hardware without one. Still, it's common for people to log into Apple accounts on their Apple TV boxes because it makes it easier to link with other Apple products. Another reason someone might link an Apple TV box with an Apple account is to use the Apple TV app, a common way to stream on Apple TV boxes. So what type of data does Apple harvest from Apple accounts? According to its privacy policy, the company gathers usage data, such as "data about your activity on and use of" Apple offerings, including "app launches within our services...; browsing history; search history; [and] product interaction." Other types of data Apple may collect from Apple accounts include transaction information (Apple says this is "data about purchases of Apple products and services or transactions facilitated by Apple, including purchases on Apple platforms"), account information ("including email address, devices registered, account status, and age"), device information (including serial number and browser type), contact information (including physical address and phone number), and payment information (including bank details). None of that is surprising considering the type of data needed to make an Apple account work. Many Apple TV users can expect Apple to gather more data from their Apple account usage on other devices, such as iPhones or Macs. However, if you use the same Apple account across multiple devices, Apple recognizes that all the data it has collected from, for example, your iPhone activity, also applies to you as an Apple TV user. A potential workaround could be maintaining multiple Apple accounts. With an Apple account solely dedicated to your Apple TV box and Apple TV hardware and software tracking disabled as much as possible, Apple would have minimal data to ascribe to you as an Apple TV owner. You can also use your Apple TV box without an Apple account, but then you won't be able to use the Apple TV app, one of the device's key features. Data collection via the Apple TV app You can download third-party apps like Netflix and Hulu onto an Apple TV box, but most TV and movie watching on Apple TV boxes likely occurs via the Apple TV app. The app is necessary for watching content on the Apple TV+ streaming service, but it also drives usage by providing access to the libraries of many (but not all) popular streaming apps in one location. So understanding the Apple TV app’s privacy policy is critical to evaluating how private Apple TV activity truly is. As expected, some of the data the app gathers is necessary for the software to work. That includes, according to the app's privacy policy, "information about your purchases, downloads, activity in the Apple TV app, the content you watch, and where you watch it in the Apple TV app and in connected apps on any of your supported devices." That all makes sense for ensuring that the app remembers things like which episode of Severance you're on across devices. Apple collects other data, though, that isn't necessary for functionality. It says it gathers data on things like the "features you use (for example, Continue Watching or Library)," content pages you view, how you interact with notifications, and approximate location information (that Apple says doesn't identify users) to help improve the app. Additionally, Apple tracks the terms you search for within the app, per its policy: We use Apple TV search data to improve models that power Apple TV. For example, aggregate Apple TV search queries are used to fine-tune the Apple TV search model. This data usage is less intrusive than that of other streaming devices, which might track your activity and then sell that data to third-party advertisers. But some people may be hesitant about having any of their activities tracked to benefit a multi-trillion-dollar conglomerate. Data collected from the Apple TV app used for ads By default, the Apple TV app also tracks "what you watch, your purchases, subscriptions, downloads, browsing, and other activities in the Apple TV app" to make personalized content recommendations. Content recommendations aren't ads in the traditional sense but instead provide a way for Apple to push you toward products by analyzing data it has on you. You can disable the Apple TV app's personalized recommendations, but it's a little harder than you might expect since you can't do it through the app. Instead, you need to go to the Apple TV settings and then select Apps > TV > Use Play History > Off. The most privacy-conscious users may wish that personalized recommendations were off by default. Darío Maestro, senior legal fellow at the nonprofit Surveillance Technology Oversight Project (STOP), noted to Ars that even though Apple TV users can opt out of personalized content recommendations, "many will not realize they can." Apple can also use data it gathers on you from the Apple TV app to serve traditional ads. If you allow your Apple TV box to track your location, the Apple TV app can also track your location. That data can "be used to serve geographically relevant ads," according to the Apple TV app privacy policy. Location tracking, however, is off by default on Apple TV boxes. Apple's tvOS doesn't have integrated ads. For comparison, some TV OSes, like Roku OS and LG's webOS, show ads on the OS's home screen and/or when showing screensavers. But data gathered from the Apple TV app can still help Apple's advertising efforts. This can happen if you allow personalized ads in other Apple apps serving targeted apps, such as Apple News, the App Store, or Stocks. In such cases, Apple may apply data gathered from the Apple TV app, "including information about the movies and TV shows you purchase from Apple, to serve ads in those apps that are more relevant to you," the Apple TV app privacy policy says. Apple also provides third-party advertisers and strategic partners with "non-personal data" gathered from the Apple TV app: We provide some non-personal data to our advertisers and strategic partners that work with Apple to provide our products and services, help Apple market to customers, and sell ads on Apple’s behalf to display on the App Store and Apple News and Stocks. Apple also shares non-personal data from the Apple TV with third parties, such as content owners, so they can pay royalties, gauge how much people are watching their shows or movies, "and improve their associated products and services," Apple says. Apple's policy notes: For example, we may share non-personal data about your transactions, viewing activity, and region, as well as aggregated user demographics[,] such as age group and gender (which may be inferred from information such as your name and salutation in your Apple Account), to Apple TV strategic partners, such as content owners, so that they can measure the performance of their creative work [and] meet royalty and accounting requirements. When reached for comment, an Apple spokesperson told Ars that Apple TV users can clear their play history from the app. All that said, the Apple TV app still shares far less data with third parties than other streaming apps. Netflix, for example, says it discloses some personal information to advertising companies "in order to select Advertisements shown on Netflix, to facilitate interaction with Advertisements, and to measure and improve effectiveness of Advertisements." Warner Bros. Discovery says it discloses information about Max viewers "with advertisers, ad agencies, ad networks and platforms, and other companies to provide advertising to you based on your interests." And Disney+ users have Nielsen tracking on by default. What if you use Siri? You can easily deactivate Siri when setting up an Apple TV. But those who opt to keep the voice assistant and the ability to control Apple TV with their voice take somewhat of a privacy hit. According to the privacy policy accessible in Apple TV boxes' settings, Apple boxes automatically send all Siri requests to Apple's servers. If you opt into using Siri data to "Improve Siri and Dictation," Apple will store your audio data. If you opt out, audio data won't be stored, but per the policy: In all cases, transcripts of your interactions will be sent to Apple to process your requests and may be stored by Apple. Apple TV boxes also send audio and transcriptions of dictation input to Apple servers for processing. Apple says it doesn't store the audio but may store transcriptions of the audio. If you opt to "Improve Siri and Dictation," Apple says your history of voice requests isn't tied to your Apple account or email. But Apple is vague about how long it may store data related to voice input performed with the Apple TV if you choose this option. The policy states: Your request history, which includes transcripts and any related request data, is associated with a random identifier for up to six months and is not tied to your Apple Account or email address. After six months, you request history is disassociated from the random identifier and may be retained for up to two years. Apple may use this data to develop and improve Siri, Dictation, Search, and limited other language processing functionality in Apple products ... Apple may also review a subset of the transcripts of your interactions and this ... may be kept beyond two years for the ongoing improvements of products and services. Apple promises not to use Siri and voice data to build marketing profiles or sell them to third parties, but it hasn't always adhered to that commitment. In January, Apple agreed to pay $95 million to settle a class-action lawsuit accusing Siri of recording private conversations and sharing them with third parties for targeted ads. In 2019, contractors reported hearing private conversations and recorded sex via Siri-gathered audio. Outside of Apple, we've seen voice request data used questionably, including in criminal trials and by corporate employees. Siri and dictation data also represent additional ways a person's Apple TV usage might be unexpectedly analyzed to fuel Apple's business. Automatic content recognition Apple TVs aren't preloaded with automatic content recognition (ACR), an Apple spokesperson confirmed to Ars, another plus for privacy advocates. But ACR is software, so Apple could technically add it to Apple TV boxes via a software update at some point. Sherman Li, the founder of Enswers, the company that first put ACR in Samsung TVs, confirmed to Ars that it's technically possible for Apple to add ACR to already-purchased Apple boxes. Years ago, Enswers retroactively added ACR to other types of streaming hardware, including Samsung and LG smart TVs. (Enswers was acquired by Gracenote, which Nielsen now owns.) In general, though, there are challenges to adding ACR to hardware that people already own, Li explained: Everyone believes, in theory, you can add ACR anywhere you want at any time because it's software, but because of the way [hardware is] architected... the interplay between the chipsets, like the SoCs, and the firmware is different in a lot of situations. Li pointed to numerous variables that could prevent ACR from being retroactively added to any type of streaming hardware, "including access to video frame buffers, audio streams, networking connectivity, security protocols, OSes, and app interface communication layers, especially at different levels of the stack in these devices, depending on the implementation." Due to the complexity of Apple TV boxes, Li suspects it would be difficult to add ACR to already-purchased Apple TVs. It would likely be simpler for Apple to release a new box with ACR if it ever decided to go down that route. If Apple were to add ACR to old or new Apple TV boxes, the devices would be far less private, and the move would be highly unpopular and eliminate one of the Apple TV's biggest draws. However, Apple reportedly has a growing interest in advertising to streaming subscribers. The Apple TV+ streaming service doesn't currently show commercials, but the company is rumored to be exploring a potential ad tier. The suspicions stem from a reported meeting between Apple and the United Kingdom's ratings body, Barb, to discuss how it might track ads on Apple TV+, according to a July report from The Telegraph. Since 2023, Apple has also hired several prominent names in advertising, including a former head of advertising at NBCUniversal and a new head of video ad sales. Further, Apple TV+ is one of the few streaming services to remain ad-free, and it's reported to be losing Apple $1 billion per year since its launch. One day soon, Apple may have much more reason to care about advertising in streaming and being able to track the activities of people who use its streaming offerings. That has implications for Apple TV box users. "The more Apple creeps into the targeted ads space, the less I’ll trust them to uphold their privacy promises. You can imagine Apple TV being a natural progression for selling ads," PIRG's Cross said. Somewhat ironically, Apple has marketed its approach to privacy as a positive for advertisers. "Apple’s commitment to privacy and personal relevancy builds trust amongst readers, driving a willingness to engage with content and ads alike," Apple's advertising guide for buying ads on Apple News and Stocks reads. The most private streaming gadget It remains technologically possible for Apple to introduce intrusive tracking or ads to Apple TV boxes, but for now, the streaming devices are more private than the vast majority of alternatives, save for dumb TVs (which are incredibly hard to find these days). And if Apple follows its own policies, much of the data it gathers should be kept in-house. However, those with strong privacy concerns should be aware that Apple does track certain tvOS activities, especially those that happen through Apple accounts, voice interaction, or the Apple TV app. And while most of Apple's streaming hardware and software settings prioritize privacy by default, some advocates believe there's room for improvement. For example, STOP's Maestro said: Unlike in the [European Union], where the upcoming Data Act will set clearer rules on transfers of data generated by smart devices, the US has no real legislation governing what happens with your data once it reaches Apple's servers. Users are left with little way to verify those privacy promises. Maestro suggested that Apple could address these concerns by making it easier for people to conduct security research on smart device software. "Allowing the development of alternative or modified software that can evaluate privacy settings could also increase user trust and better uphold Apple's public commitment to privacy," Maestro said. There are ways to limit the amount of data that advertisers can get from your Apple TV. But if you use the Apple TV app, Apple can use your activity to help make business decisions—and therefore money. As you might expect from a device that connects to the Internet and lets you stream shows and movies, Apple TV boxes aren't totally incapable of tracking you. But they're still the best recommendation for streaming users seeking hardware with more privacy and fewer ads.
