It 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.

The sensor already uses phase detection autofocus. You can create a depth map out of it. iPhone X used its dual cameras and that phase data for depth maps.

How? Is this for every image taken, or does one need to take a second photo? Or is it "in theory phase detection hardware would let you make a depth map"

Agree with the weakness, but the benefit of provenance is still there. You can't tell if the picture that person took is of an AI image, but there's some value in saying "I took this" and being able to prove it.

How does this actually work though? 1) I see a photo online and doubt it's provenance 2) I contact the photographer and ask to see their cloud image (???!) 2a) I borrow someone's mac to download the image (.jpg?) and it can be verified on that?

Ideally it’d be linked to public key on a DNS txt record or similar, and trustworthy clients (including social media apps) show the domain linked to the photo.

The 'ol "analog hole". Never been able to patch that gap.

Yes, 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?

Images 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?

Still on a 12 Pro Max, which I bought near the original launch. It is in need of its first replacement battery. I’m very curious to see how much snappier it feels with this next iOS release which is focused a bunch on performance; in addition to a new battery, since I believe my iOS is throttling performance given the health.

I still have my 11. The battery is garbage on it, but everything is still totally fine. Haven't upgraded to iOS 26 though...

11 Pro Max. First battery needs replacement but it's ok on iOS 27. I don't need or want a new phone.
