> So… a nation-state can't really do anything here unless they acquire alien technology. At least for the image itself, using direct projection onto the sensor

  They mention something about image heuristics typical of an iPhone image, that may mean that this reference mode takes a spatial image using dual sensors that help convince the PCC that it's an image of something real. Or perhaps it uses a lidar sensor, both lidar and reference mode are only offered on the Pro models. The whole camera system is one module so it could be using all of it. Regardless, you'd need a pretty complex setup and a deep understanding of the image sensors to project something that looks real. We really don't know what is in that first lump of signed sensor data. But at the end of the day, even if you manage to get a fake reference image, it's still on the person making the claim to show that the content of the image is real. A reference image of a document is useless, the physical document could be a forgery. A photo of people could be refuted with alibis during the timestamp window (max 15 minutes it sounds like?). A photo of property damage doesn't prove how or when it happened.
