I'm not really sure if I follow your suggestion; what would be done with the camera? Authenticate that a picture is real? I'm not sure how that will be workable? For example, how would I (random internet person) verify a picture from you (also random internet person) is real?
You can verify that a particular camera produced a particular photograph. Essentially, the camera would sign the photograph. Random internet person to other random internet person it wouldn't matter, I imagine. But for, say, a news paper, they can verify that a particular image was produced by a particular camera at a particular time.
