"The Coalition for Content Provenance and Authenticity, or C2PA, designed an open technical standard that essentially enforces transparency on a piece of media, providing information on how it was created and what, if any, modifications have been made. Appearing as a digital watermark (the C2PA likens it to a nutrition label), Content Credentials will be present in all photos taken by a Pixel 10 camera, and that imprint will also be viewable by anyone using Google Photos."
