tech π Microsoft AI watermarks link images to user IDs
Microsoft is embedding invisible watermarks in AI-generated images within Paint and Photos apps for Windows. A researcher found that these watermarks use a globally unique identifier (GUID) linked to the original user prompt. This system functions by sending the prompt to Microsoft for moderation before returning the encoded GUID. The practice raises privacy concerns as it could potentially identify users based on the image watermark. Users concerned about tracking might look into open-weight models like Stable Diffusion.
