How will remote attestation prove that you were actually standing on the balcony pointing the camera, and not recording some slop you generated? The analog hole is a real problem.

Don't worry, photographs were being faked before Lee Harvey Oswald.

The optical data will be cryptographically bound to the state of the autofocus mechanism and to the output of a LiDAR scanner.

We know it is practical to have a LiDAR scanner in the same assembly as an image sensor because the rear camera bump of the iPhone Pro has a LiDAR scanner.

The technology need not be 100% tamper-proof to have a large effect on society: there is a huge difference in persuasiveness between the claim that anyone could have created a particular video by submitting to an AI some starting videos and images and some prompts and the claim that anyone with years of training and experience in cutting-edge microelectronics could have bought 500 iPhones and used very expensive equipment to create 499 ruined iPhones and one iPhone that can be used to create false attestations of recordings -- particularly because in a high profile instance such as a repeat of the Rodney King beating, Apple engineering would tend to be very interested in examining the device used to make the recording.
