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.
