Content Credentials (C2PA)

Also known as: Content Credentials, C2PA manifest, C2PA

Content Credentials are the provenance records defined by the technical specification of the Coalition for Content Provenance and Authenticity (C2PA): a digitally signed manifest of assertions about an asset — such as how it was created and edited, including with AI — bound to the asset so that tampering can be detected.

In one sentence

Content Credentials (C2PA): signed provenance manifests bound to an asset that record its creation and edits; they show origin, not truth.

Example

A product photo edited with a generative fill tool carries a C2PA manifest stating the editing actions; a verification tool shows the signer and whether the image was changed after signing.

How it applies

  • Structure: Statements about an asset (assertions, for example on capture, edit actions or AI involvement) are combined into a claim, which the claim generator signs on behalf of a signer. Together they form the C2PA manifest, embedded in the file or stored externally.
  • Binding: Hard bindings (cryptographic hashes) tie the manifest to the exact content; soft bindings (fingerprints or invisible watermarks) help find a manifest again when a file was re-encoded or the manifest was stripped.
  • Documentation practice: Images, illustrations and videos in technical documentation can carry credentials that record which tools, including generative ones, were used. Text-based documentation more often relies on metadata and audit trails, since many delivery formats strip embedded data.
  • Regulation: Machine-readable provenance is one way providers of generative AI systems can meet the marking duty of Article 50(2) of the AI Act; using the specification does not by itself establish compliance.
  • Limits: The specification deliberately makes no judgment on whether content is true or good — only whether the assertions can be validated, are correctly formed and free from tampering. Missing credentials prove nothing, because manifests can be removed or were never created.

Content Credentials vs. watermarks

A watermark is a signal hidden in the content itself. A C2PA manifest is a signed record attached to or referenced by the content; watermarks can serve as one of its soft bindings.
