A Context Sensitive Tiling System for Information Hiding.
Philip C. Ritchey, Vernon J. Rego · 2012
Abstract. We present a novel and general method to procedurally generate images for the purposes of hiding information. The generation method is realized as a twodimensional tiling system, even though its generalization is not restricted in dimension or even in form. Empirical results on capacity, robustness and security are presented. The method can be generalized to obtain a framework that can create generic multimedia steganographic objects which hide information in a way that moves the embedding locale from the level of noise to higher levels in the semantics of the cover context. Two steganalysis methods are presented which are aimed at detecting steganography in objects generated using tiling systems. The detection methods are tested against the stego-system and their accuracies are reported.
