As a programmer, I gotta say, that's probably not technically feasible in a sensible way.

Every camera has got to have an embedded key, and if any one of them leaks, the system becomes worthless.

No, that would actually be feasible with enough effort.

The real question is what do you do if someone takes a screenshot of that image? Since the picture must be in a format that can be shown, nothing is stopping people from writing software that just strips the authentication from the camera file.

Edit: misread the problem. You need to get a private key to make forgeries and be able to say "no look, this was taken with a camera". Stripping the signature from photographs is the opposite of what we want here.

The point is, without the signature then there’s plausible deniability that it wasn’t real. If you want to prove something happened, then it should have a signature and be validated.

If someone is showing off a screenshot of an image then in the future (now really) one probably needs to assume it’s fake unless there’s some overriding proof otherwise.
