The Content Authenticity Initiative (CAI), led by Adobe, is a coalition advancing open technical standards for content provenance and authenticity. CAI's C2PA (Coalition for Content Provenance and Authenticity) standard enables cryptographic attestation of image origin, which allows cameras, editing software, and AI tools to embed verifiable metadata indicating when and how an image was created. When C2PA-signed images are examined, manipulations can be detected by the break in the cryptographic chain. For NCII cases, C2PA evidence can help indicate that content was AI-generated or manipulated.

Key facts about this term

  1. Understand C2PA as an emerging NCII evidence tool C2PA credentials provide cryptographic evidence of image provenance relevant to NCII prosecution.
  2. Use C2PA-enabled cameras for important event photography Leica, Nikon, and Sony have introduced C2PA-enabled cameras that prove authenticity of real photographs.
  3. Cite C2PA evidence in NCII legal proceedings C2PA provenance data can support both criminal prosecution (indicating content was AI-generated) and civil proceedings.

Frequently asked questions

Does all digital content have C2PA metadata?

No. C2PA adoption is growing but not yet universal. Most existing photos and videos do not carry C2PA credentials. The standard is being adopted by major camera manufacturers and AI tools.

Can C2PA prove a deepfake is fake?

C2PA can prove that an image lacks the expected provenance chain of an authentic photo. Combined with deepfake detection analysis, it provides strong evidence of synthetic generation.
