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