Signed text copied into most apps and sites keeps its label; some apps strip the invisible characters and the check then finds no label; editing the words breaks the seal and the check shows the change.

C2PA text manifestsC2PA manifest: The signed label itself: a small package inside a file that records who signed it, what they declared and how to check it.

Why newsrooms need a label

A file with its label inside reaches a reader who checks it on the spot; a file whose record stays on a ledger reaches the reader with nothing pointing to that record.
A label inside the file travels with it. A ledger record stays behind.

Your stories are copied and reposted within minutes. Readers cannot tell your original from a copy. AI systems take in your archive with no record of who owns it.

Tested against the standard

A checker trusts a signature when the signer's certificate was issued by a certificate authority on the C2PA Trust List, and trusts the timestamp when it comes from an authority on the C2PA TSA Trust List. The Conforming Products List shows the signing tool was tested.
Trust is about who signed and when. It does not make the content true.
