C2PA
C2PA is the Coalition for Content Provenance and Authenticity — the open technical standard for attaching verifiable, cryptographically signed provenance metadata to digital media files.
C2PA was founded in 2021 by a group including Adobe, Microsoft, the BBC, Intel, Arm, Truepic, and Sony. It defines how a provenance record is structured, signed, and verified, using established technologies such as X.509 certificates — the same trust model behind HTTPS. The standard is royalty-free, with open-source core tooling.
C2PA is now moving from voluntary industry standard toward regulatory baseline. Its AI-disclosure assertion directly satisfies machine-readable labeling requirements such as those in the EU AI Act. For brands, C2PA is becoming the default infrastructure for proving — and disclosing — how their content was made.
