C2PA signed provenance

Understand C2PA manifests, signed provenance, detection, and the boundary between presence and validation.

Definition

C2PA is a technical standard for cryptographically bound provenance assertions and ingredient relationships.

Example

A manifest can describe creation or editing actions and identify a claim generator, subject to signature and trust validation.

How to inspect

This release detects common C2PA container signals. It clearly distinguishes data detected from cryptographic validation performed.

How this product uses it

C2PA Content Credentials remain a separate optional mechanism. The app does not call them an EU certificate or legal approval.

Limitations

Signing and cryptographic verification are unavailable in this release. Manifest presence does not prove truth or regulatory compliance.
