| If that became popular, the AIs would learn how to generate a realistic depth map along with any generated image. |

| The photos are cryptographically signed in the apple image pipeline so it's not as simple as just AI generating something. That said, I can't see how this is any different to all the other times we have embedded crypto keys in consumer hardware where eventually someone finds a way to extract the key and the whole thing is busted open. |

| ▲ | Gigachad 16 minutes ago | parent [-] | | That's a good point, You might still be able to trick the cloud to sign your photos, but that's something they could patch in updates without losing control of the key. They could have the server only sign photos taken on the latest ios version. | | |

| How would that work? I thought the premise here is that you can fool the apple camera by taking a (very carefully aligned) picture of a still image (printed out). A depth map from the apple camera (again, signed) would show that the entire image had the same distance from the camera. |

| Even simpler, a 3D printed relief with an image "stamped" on it, now you effectively have a 3D image. |

| ▲ | embedding-shape 43 minutes ago | parent [-] | | ... don't make it so shallow then. Perfectly possible in a consumer-friendly 3D printer for a face or even human body if you have lots of time for the prints. | | |
