Content provenance (C2PA)

By Updated

Signed, tamper-evident information about where a piece of content came from and how it was edited, bound to the asset. The C2PA specification packages it as a manifest of assertions, a claim and a claim signature 1; NIST treats provenance tracking as one approach to synthetic-content transparency 2.

  • Deepfake

    Under the EU AI Act, a deep fake is AI-generated or manipulated image, audio or video content that resembles existing persons, objects, places, entities or…

  • Transparency

    In NIST's framing, how far information about an AI system and its outputs reaches the people who interact with it: what happened.
