New data poisoning tool would punish AI for scraping art without permission

Researchers at the University of Chicago have developed a tool that gives artists the ability to “poison” their digital art in order to stop developers from training artificial intelligence (AI) systems on their work. 

Called “Nightshade,” after the family of plants, some of which are known for their poisonous berries, the tool modifies images in such a way that their inclusion contaminates the datasets used to train AI with incorrect information.

According to a report from MIT’s Technology Review, Nightshade changes the pixels of a digital image in order to trick an AI system into misinterpreting it. As examples, Tech Review mentions convincing the AI that an image of a cat is…
