And Apple Corporation can verify that the iPhone that was supposed to have taken the picture has been registered to Mr. Joe Blow. So if the picture is an embarrassing picture of a politician and if the picture is phony then Mr. Blow must be involved. Mr. Blow is either an innocent bystander who got his iPhone hacked and his secret key stolen, or he is actively engaged in deception because he wants the politician to lose the next election. But if there's no evidence of any hacking and if Mr. Blow has no history of criminality and seems pretty apolitical and if it's not impossible that the politician could have been at that place at that time, then it would be reasonable to conclude that the photograph was real. That's certainly an improvement to what we have now; a photograph with no provenance at all, an anonymous person just posts a picture on the Internet with no hint about where or when the picture was taken or by who.
