In this paper, we analyze the security of a self-recovery fragile watermarking scheme proposed by C. Wang et al. The scheme is designed to control images integrity by locating the tampered areas and then recover the tampered zones. An attack against C. Wang et al.'s scheme is demonstrated, and we were able to manipulate the watermarked images without being detected by the extraction scheme. The theoretical and experimental results show that the proposed scheme is not secure against attacks.
