AI images are getting harder to spot. Google thinks it has a solution.

Microsoft has started a coalition of tech companies and media companies to develop a common standard for watermarking AI images, and the company has said it is researching new methods to track AI images. The company also places a small visible watermark in the corner of images generated by its AI tools. OpenAI, whose Dall-E image generator helped kick off the wave of interest in AI last year, also adds a visible watermark. AI researchers have suggested ways of embedding digital watermarks that the human eye can't see but can be identified by a computer.
