Verify Signatures or Leave Unresolved — Verify Signatures or Leave Unresolved

Evaluating the trustworthiness of a photo relies heavily on identifying the signer associated with the cryptographic signing key. A validator helps establish trust by verifying the digital signature, checking its associated credentials, and validating individual assertions.

The C2PA specification does not make value judgments on whether provenance data is good or bad, but only whether it is valid and free from tampering. If cryptographic signatures or assertions cannot be validated, the authenticity of the media should remain unverified.
