Can't I just point my camera at an AI generated image? And it will get the stamp of authenticity?

- llukas 7d agoStamp only proves you did the photo and probably some metadata like when where etc. It helps but doesn't solve credibility issue.
- lokar 7d agowhat is it missing then?
- intrasight 7d agoThe credibility comes from who took the photo. The next logical and easy step is for this metadata to flow to the user agent. I'll know that it was taken by a legit journalist photographer. And id not, I can have my user agent make it fuzzy or replaced with a kitten photo.
- Gigachad 7d agoI think this is where we are headed. This feature seems useless on it's own since someone will eventually find a way to extract the key from the iphone and sign any image. But if they could make it so every iphone uses it's own key and the photos show "Taken by xyz" and it's linked to their icloud or identity somehow. That way images shared around will still be able to be linked to a source that you can choose to trust and the viewer can know it wasn't modified from what that person shot. Then we might move to an age where photos which were not signed by someone will be treated as fake.
- intrasight 7d agoI don't think we'll treat them as fake but they would probably undergo more scrutiny - perhaps in a crowd-sourced manner that provides an overall score of probable legitimacy.
- teaearlgraycold 7d agoPhones all have hardware security modules with keys stored inside. That will absolutely be in use for this new feature.
- mikestorrent 7d agoYou may have forgotten that the world is driven by screenshots, and so a screenshot of a picture with the `(X) Verified by Apple to be Joe Schmoe` tacked on will be just as good as real verification for a lot of people. What we need is almost something like the classic "press C+A+D to log in" or the idea of "above the browser pane"... something an image cannot show you unless it's legit. Perhaps a personal thumbprint icon that is different for each viewer, so you know its your device telling you that something is real and not just some mock fake thing?
- cavoirom 7d agoYou actually think the Secure Enclave is useless.
- nonethewiser 7d agoRight. All of your pictures will include identifying information. Same will happen for LLM generated text.
- dabinat 7d agoIt would be great if they could use the LiDAR scanner to sign a depth map of the scene in front of the camera. It would show if you photographed a flat image.
- dwattttt 7d agoThe 'ol "analog hole". Never been able to patch that gap.
- lxgr 7d agoYes, if your adversary can generate a high-fidelity 3D moving replica of a scene, they can deceive you that it’s real. But can they really?
- dwattttt 7d agoImages that are meant to be 2d (E.g. a photo of something on paper) isn't going to look 3d. I guess this approach will just have to let anything flat through?
- lxgr 6d ago"I took a real photo of this image printed on paper" seems possible to falsify, yeah, but that doesn't seem too surprising to me, given that anyone with a printer can print literally any possible image.
- w4der 7d agoAnd what if you take a picture across a IR-filtered window?
- apetresc 7d agoThen you won’t be able to prove it was a genuine photograph? That sounds like the right failure mode.

- dymk 7d agoIt will look like you took a picture of a screen or print out
- michaelt 7d agoPeople have constructed video walls so high resolution they can film TV series in front of them and to an audience it's indistinguishable from a real set. It's extremely cost-effective for things like space fantasy that needs lots of exotic-looking backdrops, apparently. It may not be in reach for you and I - but within reach of anyone with the budget to run a 'bot farm'
- cedilla 7d agoThe high resolution video wall is quite simple. The hard part and why this has not been done earlier is that for filming, they had to synchronize the rendered background with the movement of the camera.
- spartanatreyu 7d agoMovement is solved by tracking the camera's position and projecting the background from there. Proof of captured image with hardware-based-attestation can be increased by adding extra information besides the RGB channels, like depth mapping (which a projected screen wouldn't be able to fake), and eventually light field recording (plenoptic imaging, e.g. Lytro).
- dymk 7d agoIf they’re spending millions on faking an image, okay fine. That’s clearly not the security model intended for this feature though.
- InvertedRhodium 7d agoHow large and pixel dense does a display need to be for it to convincingly fill an image sensor? I suspect it’s significantly less than millions.

- nonethewiser 7d agoYes.
- thallium205 7d agoI bet there exists data from the 3 cameras to represent some depth to the image.
- bl4ckm0r3 7d agothat's an authentic photo, not the subject/image, the photo is authentic.
- Lord_Zero 6d agoAn important distinction but I have taken pics of pics, and sometimes its hard to tell I didn't take it directly. So now, its hard to tell I didn't directly take the photo AND its got the stamp of approval.
