On the security of a hybrid watermarking algorithm based on singular value decomposition and Radon transform

Abstract

Abstract It is shown that the hybrid watermarking algorithm proposed in the paper “Hybrid watermarking algorithm based on singular value decomposition and Radon transform” by Rastegar et al. has a fundamental flaw which leads to false-positive problem in watermarking and should not be used for proof of ownership application. A countermeasure is then proposed to overcome the flaw exhibited in the algorithm.
