> For example, a screen attack still works: photograph a screen displaying an AI image and you get a signed photo of a fake. But it's always nice seeing big actors interested in addressing this problem. Yeah, very nice. So this whole idea basically doesn't work - but we get a new stealth way to embed metadata in an image that can be used for tracking... (And a new narrative why cameras need to have TPMs and locked-down firmware as well)

Couldn't the camera encode information from the depth sensor and prevent this.

  I will make miniature dioramas and photograph them.

    At that point you've earned the fruits of your deception, just like the tricksters who spent time doing physical photo editing.

    Miniature dioramas wouldn't be size appropriate. Apple could detect faces/cars/other common objects of ~known size and verify -- or even just dump depth map for anyone to check.

  It seems to be what Apple is doing, this feature is only available on the 18 Pro's (which have depth sensor on the back), but not Duo.

Photos of photos has always been a problem. In days of old, a Polaroid photo was considered "proof of capture". I've got a Polaroid daylab 35 plus sitting in storage somewhere (https://www.instantoptions.com/wp/faqs/daylab/ https://www.instantoptions.com/wp/faqs/daylab/). You can project a slide through it onto Polaroid film, expose it, and have the image there. I was also able to find a company that did slide printing. It was possible to send them a digital image and they'd send you back a slide with that image... which I then used to make a Polaroid of that image. I had a classic 600 Polaroid photo of a UFO landing.

That signature contains time and optionally gps coords, and taking photo of a screen is not simple. So overall does solve some problem ps:most important: cam/lens settings also in the digital sig, what for a screen is different
