> How could that possibly work?

The camera uses a certificate to sign the authenticity of the photo taken and some metadata. Any editing app wraps that signature with its own signature stating it was modified. You end up with a chain of provenance. And any generated photo is either missing a chain, or when un-wrapping, its origin cert isn't from a camera.

I guarantee that the cert in the camera will be extracted and used to make fake "real pictures" sooner or later, or that fake pictures will be fed to the camera disguised as the camera's sensor data.

There are just too many ways this approach can be subverted.
