   Thinking aloud about failure modes / edge cases:

   If i create a high quality deepfake image, project it on a large screen and take a photo of that image with an iPhone (+apple verified image secure tag) ... would that resulting image be considered "authentic" by default?

   Would digital forensics accessible to lay people still be able to fact-check and call out misuse / fakery of the new secure tag.

      The system is not for detecting deepfakes. It is for proving that the data captured by an apple camera's sensor was not altered by some 3rd party hardware or software chain.

         Fair enough.

         So the chain of trust is ...

         Personal credibility of the person taking the photo with iPhone (till the moment picture is taken) + tamper-evident protection against unauthorized or anonymous edits and manipulation (after the iphone photo is published and circulated)

         Apple cannot (of course) vouch for the former.
