Review Content Credentials (C2PA)

Content Credentials are cryptographically signed C2PA provenance records bound to a digital asset that can describe who or what created or changed it and how.

A Content Credential works like a tamper-evident history attached to or associated with a piece of digital content. Compatible tools can add signed statements about capture, editing, ingredients, and the software or organization involved, and a viewer can validate the signatures and bindings.

Content Credentials can give creators, publishers, and audiences consistent evidence about a file's origin and editing history. They are useful for AI disclosure and media provenance because the history can travel across participating tools without depending on one platform's private label.

A camera creates a signed record when a photograph is captured. An editor adds a signed record for the crop and color adjustment, and a publisher adds another when releasing it. A reader can inspect the resulting provenance chain.

A Content Credential is not a truth stamp and does not prove that a depicted event happened as claimed. A credential can be absent or removed, and its assertions are only as trustworthy as the signers and trust model. It provides evidence about provenance and tampering, not automatic fact-checking.

A signed history, not a truth stamp.

* [C2PA, *Content Credentials Technical Specification*](https://spec.c2pa.org/specifications/) — the current technical standards for cryptographically bound content provenance, trust, and validation. * [C2PA, “C2PA and Content Credentials Explainer”](https://c2pa.org/specifications/specifications/2.2/explainer/Explainer.html) — explains Content Credentials as cryptographically bound structures that record an asset's provenance.

* Compare the asset-specific record with the broader history captured by [[data-provenance|Data Provenance]]. * Use [[verification|Verification]] to inspect signatures, trust chains, and whether the credential supports the claim being made.
