Content provenance
& media origin proof.
As AI-generated content proliferates, origin proof becomes essential. Attesto supports C2PA-compatible content provenance workflows — proving what was created, by whom, when, and whether it has been modified — helping organisations maintain trust in digital media.
C2PA manifest integration
Attach cryptographic C2PA manifests to media files at creation or ingest, establishing an origin proof that travels with the content across platforms.
AI generation disclosure
Record whether content was fully or partially generated or modified by an AI model — supporting platform transparency requirements and emerging disclosure obligations.
Edit history chain
Capture each edit event as a signed entry in the content manifest — from original capture to final publication — building a verifiable chain of custody.
Creator attestation
Prove the identity of the creator, organisation, or system that produced content — with cryptographic signatures resistant to spoofing.
Publication timeline
Record when content was published, on which platform, and through which distribution channel — providing a verifiable first-publication reference.
Modification detection
Any modification to content or its manifest after signing produces a detectable mismatch. Tampering is mathematically visible and verifiable by any recipient.
