Provenance
C2PA Content Credentials: what does a valid signature mean?
C2PA is a provenance standard. A valid integrity result means the signed claims and asset binding pass the verifier; it does not automatically mean the issuer is trusted, the image is authentic in every sense, or that it was made by AI.
Three questions to keep separate
First ask whether a C2PA manifest is present. Then ask whether its cryptographic integrity validates. Finally ask whether the issuer is trusted in your context. The checker reports these as separate states.
Without configured trust anchors, AI Metadata Remover must not display a generic “trusted” label. An unknown issuer can still have a mathematically valid signature.
What a failed validation tells you
A tampered asset or invalid claim should be treated as unresolved provenance evidence. It is not proof that the image is fake or AI-generated.
If the browser verifier cannot safely parse a format, the interface falls back to the existing embedded/unverified finding instead of blocking ordinary metadata scanning.
What this tool cannot promise
- Issuer trust is not inferred from a valid signature.
- External provenance histories are not fetched or guaranteed.
- The feature does not detect SynthID or pixel watermarks.
Quick answer
Does removing an embedded credential erase external provenance? No. It only changes the new local copy; external records and platform-side histories are outside this tool.
