The timestamp system seems like it provides more benefit than signing the image data itself, at least in terms of difficulty to fake. As long as rolling back the stored timestamp token is prevented, I would have to find a phone that never updated its timestamp after the time I want to fake. Of course you could potentially find a phone that last connected to Apple's servers with a plausible timestamp. Even then the up…
There are already plenty of insurances that require you to submit claims through a smartphone app that tries to essentially do this by capturing sensor metadata etc. - those don't need to be nation-state resilient, just Joe the Crackhead Insurance Scammer resilient, so this works. Likewise, more and more things online require identity verification (either officially or disguised as age verification).
Edit: And while "a nation state actor can spoof this" is a problem for the journalism use case, the insurance/ID verification use cases are perfectly fine with anything that raises the bar but could be bypassed with enough effort. Also, the journalism use case suffers from the same fundamental issue all of these use cases suffer from: People will "verify" the picture by looking at the repost of a screenshot of the verification UI, not by verifying the original themselves.

> This makes it like, a thousand times harder to fake a photo than it would otherwise be. The problem with this thinking is twofold: 1) Whether it actually meaningfully increases the difficulty of a forgery remains to be seen. Despite their initial language about discerning real events, we see no details here about what scene information is used. 2) It increases the potential value of a forgery because now your forge…
You worry that a technology that you have never used nor evaluated might not work in practice... Therefore because of your worry (which is based on remarkably little information), it's a bad technology? Come the fuck on. That's beyond luddite bullshit.
You must be new around here. ;-)
A photograph by itself should never be considered proof of anything.
Lots of criticism here but I think this is extremely promising. When this tech is extended to videos and perhaps even other forms of media, I think it has the potential of stopping all slop!

Well, first, that's only expensive if you're poor. The world is absolutely full of people who can easily piss away your entire annual income throwing a house party. But I really mean that if the lidar barely works outdoors anyway then actually you don't need to be 16 feet away at all. Anyway, one may presume that they've thought about this.
Thought about it and also are bright enough not to fall for the “if a single person dies wearing a seat belt, we should abandon seat belts because they do no good at all” fallacy. It’s almost certainly possible to fool v1 of this system, for some images, in some contexts. It would be shocking if the first implementation was completely perfect. But maybe it’s better than nothing?
Knowing Apple, they've been working on and testing Apple Reference Image for years.
It being perfect isn't the issue; it's that random people on the internet who are just learning about this assume Apple's engineers haven't already thought about everything (and more) mentioned in this thread.
The fundamental issue isn't technical. It's that people will see the "certified real" tag and just take the image for face value of whatever narrative someone wants to convey. They'll see the "Real Photo, Verified by Apple" and their brain will short circuit [0] I don't think we should have this, for that reason alone (but many others too). [0]: https://imgur.com/fVPkpuQ
so what happens if you display an extremely high res image of a 100% AI generated fake-something on an 8K display in a photo studio room and take a picture of it with the camera? it gets tagged as authentic.
