What are Content Credentials (C2PA), and do they prove a photo is real?

Content Credentials are a signed history attached to a photo, video, audio file or document, showing how it was made and how it was changed. They prove that recorded history has not been tampered with since signing. They show where a file came from, which is different from proving the scene is true.

What they are

The Coalition for Content Provenance and Authenticity (C2PA) publishes an open standard called Content Credentials. It describes them as working like a nutrition label for digital content: a look at the content’s history that anyone can open (C2PA).

What they record

According to the C2PA, a credential can include how the content was created, what tools were used, when and where it was made, and how it has changed over time. Each credential is digitally signed, and any change to the file or its history breaks the signature, which shows the tampering (C2PA FAQ).

What they tell you, and what they leave to you

Credentials present and valid — you can trust the recorded history of the file. You still judge what the picture shows: a real camera can photograph a staged scene.
Credentials missing — that alone is not a sign of a fake. The C2PA notes credentials can be removed by accident or on purpose.
Credentials broken — the file or its history changed after signing. Ask why.

How to check them

Look for the small “CR” pin on sites and apps that display credentials; it opens a summary of the file’s history. The Content Credentials website also has a Verify page where you can inspect a file (contentcredentials.org).

Use them alongside other checks

Credentials are strongest together with the basics: who posted the file first, whether trusted sources confirm it, and an independent review of the file itself.

How All Around REAL helps

All Around REAL is Your AI PI. Whether a file carries credentials or not, our review examines the substance of the file itself, so even a file that has been “cleaned” of its history can still be reviewed. You get a dated, independent record and a REAL Check that anyone you choose can verify against our registry.
