Master content provenance verification using C2PA standards, digital signatures, and authenticity validation techniques.
The Coalition for Content Provenance and Authenticity (C2PA) standard provides cryptographic proof of content origin and history.
Contains claims about content creation, editing, and provenance history.
Specific claims about actions performed on the content.
Cryptographic signatures that validate the authenticity of claims.
References to source materials used in content creation.
🔗 Key Concept: C2PA creates an immutable chain of custody for digital content.
Understanding and validating the complete history of content modifications and transformations.
Validate the initial content creation claim and creator identity.
Track all documented edits, transformations, and processing steps.
Ensure no breaks or tampering in the provenance chain.
Cryptographic validation ensures the integrity and authenticity of C2PA manifests.
Certificate validity period has passed
Certificate has been revoked by CA
Signature doesn't match content
Deep analysis of C2PA manifest structure and content to understand provenance claims.
Establishing trust through certificate authority validation and issuer verification.
Valid certificate from recognized CA, known issuer
Valid certificate but unknown or unverified issuer
Invalid, expired, or self-signed certificate
