Researcher says Paint embeds remote-issued IDs in local AI images
Image: Primary A reverse-engineering report says Microsoft Paint's local image-generation path sends prompts and styles to a remote moderation service, which returns a GUID used as an invisible watermark in generated images. The report says Paint also requests a C2PA manifest and that the manifest's soft-binding value matches the watermark identifier. It says the visible-watermark setting does not govern the invisible watermark, while Microsoft discloses C2PA metadata for AI-generated images.
