The Download: watermarking AI images, and WorldCoin's backlash

The news: Google DeepMind has launched a new watermarking tool which labels whether pictures have been generated with AI. The tool, called SynthID, will allow users to generate images using Google's AI image generator Imagen, then choose whether to add a watermark. Watermarking--a technique where you hide a signal in a piece of text or an image to identify it as AI-generated--has become one of the most popular policy suggestions to curb harms. These new tools could help protect our pictures from AI. PhotoGuard and Glaze are just two new systems designed to make it harder to tinker with photos using AI tools. The finding could strengthen artists' claims that AI companies are infringing their rights.
