> our tool can verify a large family of image transformations
Is this family large enough to transform real image A into arbitrary fake image B?
> ZK-JPEG can merge transparent or translucent layers into an image, useful for placing visual watermarks, creating double exposures, or merging visual layers, potentially AI generated over portions of the image. In our tool, the transparent layer is revealed, but anything beneath an opaque portion of the layer becomes secret. Note that in the case of an AI generated layer, the layer itself is revealed, minimizing the dishonesty in using generative AI (but not minimizing the dishonesty of stealing artwork to train the AI)
Seems like the answer to my question is "yes", so you have to carefully inspect the transformations to see if they look legit. (The parenthetical was a surprising inclusion in an academic context)
