C2PA Verify logo

C2PA Verify

See who made a photo, and whether you can trust it.

CI

Google Play .apk

C2PA Verify is an Android app that reads the Content Credentials (C2PA) embedded in a photo and tells you, at a glance, where the image came from: who signed it, the tool that created it, whether it has been edited or generated by AI, and whether the signer is one you can trust.

Inspecting an AI-generated photo in C2PA Verify

Why

C2PA could be an important standard in the fight to know whats real in our increasingly AI slopped world. Some cameras are coming on the market that supported signing their photos to prove they were taken with a real camera. Some image editing software already supports C2PA data handling. But there is one gap, the last mile if you will. What does it matter if a photo has a full C2PA chain, if no one can read it?

We need to surface this information to users in a useful and easy to access manner. So this app is a first attempt at that. I imagine in the future tools like this will be build right into web-browsers and image viewers, but until they are, I hope this tool might be useful to a couple people.
