Abstract :
Sensitivity analysis attacks present a serious threat to the security of popular spread spectrum watermarking schemes. Randomization of the detector is thought to increase the immunity of such schemes against cryptanalysis. In this paper, we introduce a new attack against randomized detectors. This attack is successful, which implies that spread spectrum schemes still lack security.
