If I take a photo with a cryptographically signed camera of a polaroid containing an image that i deep faked, how does that ensure the image can be trusted?

Depth channel?

I've seen pretty good depth estimation algorithms that work off of 2D images, even without the use of AI.

Those depth estimation algorithms can't be used to distinguish a photo of a photo from just a photo. They will report false depth in a photograph of a flat photograph.

Yes, that's my point. You can't rely on the depth map in the image metadata to be the differentiator because it can easily be faked with depth estimation.

I trust that you took an unaltered picture of a Polaroid.
