CAI verification website does not list C2PA Information from test image

Downloading the image as linked from the readme and then uploading to CAI verification website shows no credentials for the asset. Are there other assets with C2PA information available to test with?

@jameswenzel Thanks for reporting this issue!

We have updated the URL of the verification website in README, and you should be able to see the CAI-injected contents on the verification website now.

Sharing more background with you:

C2PA spec is new, and we are working hard on the transition from CAI to C2PA:

  • The main branch implements the CAI spec, which is compatible with C2PA spec v0.5.0.
  • The feature-support-c2pa-photo branch implements the C2PA spec v0.7.0 (current public draft).
    • It will be the main in the coming future.

Content Authenticity Initiative are maintaining two versions of the verification website: verify-alpha (CAI) vs verify (C2PA).

Hoping that helps!
