Will signing come from the camera? At that point you run into DRM.

Besides, what will the camera sign? The produced JPG? The raw file? What about rescaling? Do we want ZKPs that a JPG was achieved by nothing more than re-scaling and tone-mapping another JPG or RAW file? Those ZKPs are going to be massively big and slow to verify.

My main concern is the faking of official statements by public figures where having those signed addresses the issue of deep fakes. Of course there has to be infrastructure in place for this and people must know that you can verify them.

If we get to a point in society where unsigned images, or images signed from a questionable source are looked at skeptically, then that alone is a step in the right direction. I don't know the final solution and I don't claim to know it, but cryptography seems like a step in the right direction.
