Original Pictures provides content-provenance and integrity infrastructure. A signed manifest attests to when an asset existed and that its bytes have not changed since; it does not prove that the depicted event is real. C2PA Trust List conformance is in progress and not yet complete. Nothing here is legal advice. Products in production today: Sign, Verify, API/SDK. Capture is a Q3 2026 app.
