What this page covers
C2PA helps content carry provenance signals. Attesto preserves surrounding enterprise evidence when metadata is stripped or disputed.
Legal timing
C2PA is an industry provenance standard, not a general EU compliance law. It becomes commercially important where organizations need to prove how media was created, edited, approved and published.
This page is implementation guidance for evidence planning, not legal advice.

FAQ
How is this different from a normal log?
A normal log asks an auditor to trust the system that produced it. Attesto records hashes, signatures, Merkle proofs and verifier receipts so selected evidence can be checked independently.
Does Attesto need to expose raw sensitive data?
No. Raw records can remain encrypted or customer-controlled while proof material is shared for verification.
Where does C2PA Content Credentials and media provenance fit in the compliance stack?
Attesto complements C2PA manifests with custody, approval and verifier receipts that live outside the media file.
