Beyond the origin - secure media provenance with C2PA
summary
C2PA defines an embedded manifest format that hashes media bytes, records ingredient chains, attaches signatures and optional timestamping and OCSP stapling for long‑term validation; deployed examples include a Sony camera and Google Pixel 10 video capture and AI services (Runway) that emit C2PA labels, and adopters like Adobe and LinkedIn. Open libraries exist (notably c2prs Rust plus JS/Python ports). Conformance enforces encrypted key storage, 90‑day patching for level one and assurance level two adds hardware attestation; it works but faces key management, performance and privacy limits.
