Paper Abstract

This paper describes an attack on semi-fragile image authentication schemes proposed in papers. In this attack, the adversary manipulates an authentic image and queries a verifier with the corrupted image. According to the answers from the verifier, the adversary can disclose the secret relationship graphs used to produce a signature. With the disclosed relationship graphs, the adversary can impersonate an innocent person to forge authentic images easily. A countermeasure to this attack is to change scheme parameters with the relationship edges so that the relationship graphs reconstructed by the attacker are different from the original one. Sequentially, the attacker is hard to forge an authentic image without correct relationship graphs.
