Durable Content Credentials

Durable Content Credentials is a concept that helps content provenance to persist across content platforms by using C2PA manifest data in conjunction with:

• Invisible watermarks, actively inserted into the content.
• Content fingerprints, passively computed from the content.

Platforms that host media assets might remove C2PA manifest data, if, for example, they use software that does not yet support the standard. If a copy of the manifest data is stored in an online database, you can use a watermark or a fingerprint to find it again. Combining both watermarks and fingerprints further improves the robustness of the provenance information.

The C2PA specification refers to watermarking and content fingerprinting as soft bindings, and requires that they be generated using one of the approved Watermarking and fingerprinting algorithms.
