About this app

GreenCheckmark is a special camera app for recording important footage. It creates verifiable videos and photos, leveraging the C2PA specifications created by Adobe, BBC, Google, Microsoft and others.

1) Viewers can independently validate the videos you shared are directly captured from camera and unmodified.
2) Sign In With Google can be used to add creator attribution
3) c2paviewer.com is a convenient tool to confirm photos you are looking at has not been edited
4) You can also view signature of photo/videos from other apps by sharing them to GreenCheckmark. The verification will show if the signature is trustworthy, along with other details.

This is a community project developed by Evergreen Labs, a non-profit organization registered in Canada.

What’s new
