Paper Abstract

Until now, the sensitivity attack was considered as a serious threat to the robustness and security of spread spectrum-based schemes, since it provides a practical method of removing watermarks with minimum attacking distortion. Nevertheless, it had not been used to tamper other watermarking algorithms, as those which use side-information. Furthermore the sensitivity attack has never been used to obtain falsely watermarked contents, also known as forgeries. In this paper a new version of the sensitivity attack based on a general formulation is proposed; this method does not require any knowledge about the detection function nor any other system parameter, but just the binary output of the detector, thus being suitable for attacking most known watermarking methods, both for tampering watermarked signals and obtaining forgeries. The soundness of this new approach is tested by empirical results.
