Towards Multi-class Blind Steganalyzer for JPEG Images of different stego programs in a three-dimensional space. This paper demonstrates that, at least under some simplifying assumptions in which the effects of double compression are ignored, it is possible to reliably classify stego images to their embedding techniques. The classifier is capable of generalizing to previously unseen techniques.

Countermeasures for Collusion Attacks Exploiting Host Signal Redundancybit both temporal and spatial self-similarities. To counter such attacking strategies, it is necessary to ensure that embedded watermarks are coherent with the redundancy of the host content. To this end, both motion-compensated watermarking and self-similarities inheritance will be surveyed.

Fingerprinting Schemes. Identifying the Guilty Sources Using Side Informationisely a codeword of the error correcting code. We present two different approaches that use side information for the tracing process. The first one uses the Guruswami-Sudan soft-decision list decoding algorithm and the second one a modified version of the Viterbi algorithm.

Max A. Chernesky,James B. Mahony analysis. Simulation results show that relatively high capacity for watermark embedding in low frequency subbands of wavelet domain is achieved with the proposed algorithm, and high robust results are observed against StirMark attacks, such as JPEG compression, additive noise, median cut and filter.

David G. Ostrow,Terence C. Gaylein this paper demonstrate how changes in natural image statistics can be used to detect watermarks and devise attacks. Such natural image statistics-based attacks may pose a serious threat against watermarking schemes which are based on quantization techniques.

However, the Shannon security may be compromised, but it remains unclear to what extent. Experimental results are presented that demonstrate the fundamental concepts.
