In 2016, Naveh and Tromer introduced PhotoProof, a novel approach to image authentication based on cryptographic proofs. We here show how to simplify PhotoProof to get a protocol closely related to redactable signature schemes. From an authenticated breeder document, we only keep the necessary fields to prove what its owner wants to assert and black out all the others to remove sensitive data from the document. We efficiently instantiate our scheme and give implementation results that show its practicality.
