ZK-JPEG: Zero-Knowledge Image Editing and Compression

    Zero-knowledge seems completely unnecessary. Surely the original image does not have any material content in it that is not made public by publishing a JPEG-compressed version.

    Could this be simpler and more efficient without ZK?

      It would be interesting if it could be made to work with arbitrary transform, such as redaction.

      Imagine a photo with some blacked out rectangles, and a ZK proof that confirms it comes from an attested "real" photo + adding those rectangles, but no other modification.
