Content Credentials
Also called C2PA
A record attached to an image, video or audio file showing how it was made and edited, including whether AI was used.
Content Credentials are a standard way to attach a file's history to the file itself: which camera or app created it, when, and what edited it. AI image tools increasingly add them to what they make, and some cameras add them to real photos.
They're useful when present and easy to lose. A screenshot, a re-save, or an upload to a site that strips file data can remove them. So a file with credentials tells you something real; a file without them tells you very little. Invisible watermarks such as Google's SynthID are a separate signal, built into the pixels or sound rather than the file's data.
For example
An image made in ChatGPT carries credentials saying so; a screenshot of that image posted online usually doesn't.
