Both can describe a media file. Only Content Credentials add a signed, verifiable provenance structure that can be checked against the asset.
Metadata remains useful. C2PA does not replace EXIF, IPTC or XMP; it gives selected provenance information a verifiable context.
The two systems can carry related information, but they answer different questions and have different trust properties.
EXIF, IPTC and XMP fields describe the file and its production context. They are widely supported, easy to read and often easy to edit or remove.
A C2PA manifest can carry declared actions, ingredients and metadata assertions, then bind them to the asset with a cryptographic signature.
The distinction is less about the words stored in the file and more about how those claims are bound, checked and interpreted.
| Question | Traditional metadata | Content Credentials |
|---|---|---|
| Primary purpose | Describe technical, editorial or rights information. | Provide signed provenance and integrity signals. |
| Integrity protection | Usually no cryptographic binding to the file. | The manifest and asset relationship can be validated cryptographically. |
| Editing | Fields can commonly be changed without a visible validation failure. | Undeclared changes may break validation unless a new valid manifest is created. |
| Trust | The reader decides whether to believe each field. | The verifier separates signature validity from certificate trust. |
| Portability | Metadata may be stripped by export, upload or optimization. | C2PA data may also be removed; recovery depends on the ecosystem and implementation. |
| ProvSeal result | Ordinary metadata alone does not create a C2PA status. | ProvSeal can show Trusted, Signed but untrusted, Invalid or No credentials. |
The important boundary is whether the information is included in the signed C2PA structure, rather than merely present elsewhere in the file.
EXIF, IPTC or XMP describes the asset.
The creator or tool chooses what to declare.
The assertions are bound into a C2PA manifest.
A verifier checks the signed structure against the asset.
Teams should preserve useful metadata while being precise about which information is actually covered by a Content Credential.
A publisher can read captions and rights metadata, then independently verify the C2PA manifest and trust result.
A DAM can retain operational metadata while protecting the attached Content Credentials through transformations and delivery.
A receiving team can distinguish ordinary descriptive fields from assertions included in the signed provenance history.
If ProvSeal shows No credentials, it means no C2PA evidence was detected. It does not mean the media is fake, and the presence of a valid credential does not guarantee that every claim is true.
Use these distinctions when documenting verification workflows or explaining results to non-technical teams.
No. C2PA can reference or include selected metadata, but these standards still serve their own descriptive and operational purposes.
No. Only information covered by the signed C2PA structure receives that cryptographic context.
Yes. Publishing systems can strip either layer. Verification explains what is present in the observed asset, not everything that may have existed before.
