MIT Technology Reviews How To series helps you get things done.Since the start of the generative AI boom, artists have been worried about losing their livelihoods to AI tools. There have been plenty of examples of companies replacing human labor with computer programs. Most recently, Coca-Cola sparked controversy by creating a new Christmas ad with generative AI.Artists and writers have launched several lawsuits against AI companies, arguing that their work has been scraped into databases for training AI models without consent or compensation. Tech companies have responded that anything on the public internet falls under fair use. But it will be years until we have a legal resolution to the problem.Unfortunately, there is little you can do if your work has been scraped into a data set and used in a model that is already out there. You can, however, take steps to prevent your work from being used in the future.Here are four ways to do that.Mask your styleOne of the most popular ways artists are fighting back against AI scraping is by applying masks on their images, which protect their personal style from being copied.Tools such as Mist, Anti-DreamBooth, and Glaze add tiny changes to an images pixels that are invisible to the human eye, so that if and when images are scraped, machine-learning models cannot decipher them properly. Youll need some coding skills to run Mist and Anti-DreamBooth, but Glaze, developed by researchers at the University of Chicago, is more straightforward to apply. The tool is free and available to download as an app, or the protection can be applied online. Unsurprisingly, it is the most popular tool and has been downloaded millions of times.But defenses like these are never foolproof, and what works today might not work tomorrow. In computer security, breaking defenses is standard practice among researchers, as this helps people find weaknesses and make systems safer. Using these tools is a calculated risk: Once something is uploaded online, you lose control of it and cant retroactively add protections to images.Rethink where and how you sharePopular art profile sites such as DeviantArt and Flickr have become gold mines for AI companies searching for training data. And when you share images on platforms such as Instagram, its parent company, Meta, can use your data to build its models in perpetuity if youve shared it publicly. (See opt-outs below.)One way to prevent scraping is by not sharing images online publicly, or by making your social media profiles private. But for many creatives that is simply not an option; sharing work online is a crucial way to attract clients.Its worth considering sharing your work on Cara, a new platform created in response to the backlash against AI. Cara, which collaborates with the researchers behind Glaze, is planning to add integrations to the labs art defense tools. It automatically implements NoAI tags that tell online scrapers not to scrape images from the site. It currently relies on the goodwill of AI companies to respect artists stated wishes, but its better than nothing.Opt out of scrapingData protection laws might help you get tech companies to exclude your data from AI training. If you live somewhere that has these sorts of laws, such as the UK or the EU, you can ask tech companies to opt you out of having your data scraped for AI training. For example, you can follow these instructions for Meta. Unfortunately, opt-out requests from users in places without data protection laws are honored only at the discretion of tech companies.The site Have I Been Trained, created by the artist-run company Spawning AI, lets you search to find out if your images have ended up in popular open-source AI training data sets. The organization has partnered with two companies: Stability AI, which created Stable Diffusion, and Hugging Face, which promotes open access to AI. If you add your images to Spawning AIs Do Not Train Registry, these companies have agreed to remove your images from their training data sets before training new models. Again, unfortunately, this relies on the goodwill of AI companies and is not an industry-wide standard.If all else fails, add some poisonThe University of Chicago researchers who created Glaze have also created Nightshade, a tool that lets you add an invisible layer of poison to your images. Like Glaze, it adds invisible changes to pixels, but rather than just making it hard for AI models to interpret images, it can break future iterations of these models and make them behave unpredictably. For example, images of dogs might become cats, and handbags might become toasters. The researchers say relatively few samples of poison are needed to make an impact.You can add Nightshade to your image by downloading an app here. In the future, the team hopes to combine Glaze and Nightshade, but at the moment the two protections have to be added separately.
