GreenCheckmark is a camera app for recording footage that matters. It signs every photo and video at the moment of capture, using the C2PA specifications created by Adobe, BBC, Google, Microsoft and others.
1) Viewers can independently confirm that what you shared came directly from a camera and has not been altered since capture
2) Your iPhone's Secure Enclave holds the signing key, so it never leaves the device
3) Sign In With Apple can be used to add creator attribution
4) c2paviewer.com is a convenient way to check that a photo has not been modified since it was signed
A signature covers the file, not the photographer's judgement: it shows the capture is genuine and unedited, and it cannot tell you what the camera was pointed at. See green-checkmark.org for exactly what a GreenCheckmark does and does not prove.
This is a community project developed by Evergreen Labs, a non-profit organization registered in Canada.
