Apple's iPhone 18 Pro Can Prove a Photo Is Real—Here's How
Apple Reference Image: A New Approach for Verified Photography
Apple Reference Image is an opt-in camera mode on iPhone 18 Pro and Pro Max that creates a cryptographically signed digital negative on dedicated secure hardware, then develops it in Private Cloud Compute. It offers quantum-secure signatures, timestamp bounds, and revocation, all without revealing the photographer's identity—a new standard for verifiable photography.
It should not be necessary to forgo anonymity in order to prove image authenticity.

This is really clever from Apple. The journalist use case is just the PR story. This will be really useful for identity verification and insurance apps, and has the potential to shift from "you need a smartphone to be able to live normally" to "you need an iPhone to be able to live normally".
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.

Apple doesn't address the modified photo replay situation, where you take a picture of an already edited image.
Photoshop / AI-gen an image -> display on a high-resolution monitor -> photograph the monitor with iPhone 18 Pro -> valid Apple Reference image.
To get valid reference photos, you can go to the actual physical location, put the iPhone/monitor in a cardboard box to block external light, then photograph the monitor. Paint the inside of the box using Vantablack (stopping reflections) and cover the LiDAR projector with tape.
I can't wait to see Apple Verified™ photos of UFOs flying over the Golden Gate Bridge.

This is so insanely complex and requires placing trust in the correctness of so many pieces, many of them closed-source. And uploading every verified "developed" image to Apple's servers. And giving up full control of the software and hardware you "own". All to achieve a goal of "verifying" photons, which is only a part of the real problem of verifying the truth of an event that was photographed.
I hope that companies and governments don't start forcing us to use this stuff by requiring it for their services.

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).

To me the weakest spot of this whole endeavor is how this will create false confidence in a story just because the accompanying images pass Apple's verification.
Like with the Watch Ultra (attacking the diving-watch market with the sheer volume-scale of selling the development to everyone buying a Watch Ultra), Apple is attacking the trusted-imaging market with the same strategy.
Okay, fine. Will work for sure, this will disrupt the trusted-imaging market and moreover make Apple a service-provider in this industry (with the ramp-up cost paid by customers buying iPhones for entirely different purposes).
But creating this impression and media-buzz that Apple is now verifying more than just the digital authenticity of an image may shift the public scrutiny of MANY media/online statements:
There is a risk that random claims (and propaganda) will be given more credibility in the public eye just because they came with images that were confirmed to be "taken like this on an iPhone"

Canon tried this 20 years ago with DSLRs. Nikon had an authentication system. Both were broken. The keys ended up on Pastebin. Apple's hardware security is better, but history suggests this is a temporary advantage. The real question is whether the system will be revoked when (not if) it's broken, and whether Apple will have the guts to retroactively invalidate millions of "verified' photos"

That's a lot of words to say "we re-invented C2PA but made worse by getting our servers involved somehow".
Like with C2PA, the entire thing hinges on nobody being able to dump keys or trick the TPM into signing arbitrary image data. The timestamping server is a nice idea (though I don't see why they can't just use a normal timestamping server, I guess to keep control over the protocol) but it doesn't solve the fundamental problem that defeated C2PA.

This approach assumes that the smartphone in question is not under the user’s control. That should generally not be the case. When I buy a device, I have the right to install whatever I want on it and to make the camera sensors believe whatever I want. If something cannot be implemented securely under these circumstances, it’s not a good idea, and other solutions are needed. I once tested a video identification system for a company that the manufacturer claimed was absolutely secure. All it took was rooting the smartphone and bypassing the root detection. After that, you could play any pre recorded video, which would then be recognized as camera input. Under those conditions, it was easy to manipulate a video so that a company employee would consider it real enough to verify the test subject.
It’s simply not technically possible to verify the authenticity of the camera input with 100% certainty. Pretending that it is possible only creates problems. Then someone fakes evidence, but all the normies who have no clue about technology assume that it must be real. You see this with AI detectors too they recognize random texts as generated, yet an unbelievable number of people believe them.

I‘ve been wondering whether the contact tracking features introduced for Covid 19 could be used to verify that pictures of an event where taken by people who were actually around the scene. That way you‘d have some reassurance that a given picture was actually from the event. Combined with pictures from different angles from different people and some
kind of verified photography should make alterations harder.

We need this for video and audio, with metadata baked in. “I didn’t say that.” “This recording says you did.”
