Robustness and Efficiency of Non-linear Side-Informed Watermarkingutput, it has been shown that hypothesis tests using such detectors are highly efficient. This paper presents further analysis of these non-linear schemes, focusing in particular on the robustness of the schemes in the presence of noise and the use of periodic filtering functions in order to reduce interference from the host signal.

Limits of Anonymity in Open Environmentsrate our attack. The MIX method forms the basis of most of the today’s deployments of anonymity services (e.g. Freedom, Onion Routing, Webmix). We note that our approach is general and can be applied equally well to other anonymity providing techniques.

Cryptanalysis of Discrete-Sequence Spread Spectrum Watermarksloits the host and . correlations, and the fact that one can locally correct errors in the . estimates if the watermarking coefficients are discrete. It is natural to use error-correction codes in a watermarking algorithm, and we study the effects of the accompanying redundancy as well.

A Steganographic Embedding Undetectable by JPEG Compatibility Steganalysisbe detected by their steganalysis mechanism. Furthermore, we claim that our method can also be used as a steganographic method on files stored in JPEG format. The method described herein uses a novel, topological approach to embedding. The paper also outlines some extensions to the proposed embedding method.

Robust Image Watermark Using Radon Transform and Bispectrum Invariantss detection of the watermark when there is no exact inverse function during embedding. As we use the Radon transform, our method can be used for medical images. We show the invariance of the designed watermark with mathematical proofs. Experimental results confirm that this scheme is resistant to geometric distortions.
