Verify a Authenticity

An authenticity attestation records the provenance signals on a piece of media — its content hash, C2PA content credentials, watermark payload, and any linked attestation. Verification surfaces exactly which of those signals are present.

How to verify

  1. 1Find your authenticity ID (looks like cert_…).
  2. 2Paste it into the proof portal and verify. No account required.
  3. 3The result shows the cryptographic checks the record actually carries — signature, hash, and any RFC 3161 / Bitcoin timestamps.
