About Green Checkmark C2PA Verifier

This tool verifies the C2PA signature embedded in photos and videos created by the GreenCheckmark app. It shows users an "Invalid Signature" warning if the photo may have been modified since it was recording. A "Valid Signature" will be shown if the certificate chain is valid. https://green-checkmark.org
