- C2PA (Content Credentials) uses cryptographic signatures and PKI to verify image authorship and prevent forgery.
- C2PA is currently not widely adopted—most images lack signatures, while nearly all signed ones are AI-generated, making it useless for distinguishing AI from human content.
- For C2PA to be effective, universal signing by all cameras and phones, along with metadata preservation by social media platforms, is required, likely needing further regulation.
- C2PA signatures can be stripped or bypassed by sophisticated users, but it may still reduce AI content spread among average users.
- The EU AI Act mandates AI content tagging, but C2PA's real utility depends on future adoption and technical integration across devices and platforms.
