It’s not just a sig on the image, but on metadata as well. Harder to fake time + place if they implement it thoroughly. (I.e., they would have to make it only trust GPS and verify against an internal clock, I suppose, and not allow updating time and location manually.)
…including the date and time a photo was taken as well as its location and the photographer…
Not including gps and time makes this worse, but including it makes it useless because you can’t ever verify a photo sent across social media, since the exit tags will be stripped.
