Executive Summary

In this paper is proposed a novel steganographic scheme based on chaotic iterations. This research work takes place into the information hiding security fields. The authors show that the proposed scheme is stego secure, which is the highest level of security in a well defined and studied category of attack called "Watermark-only attack". Additionally, they prove that this scheme presents topological properties so that it is one of the firsts able to face, at least partially, an adversary when considering the others categories of attacks defined in the literature. Robustness and security are two major concerns in information hiding. These two concerns have been defined in as follows. "Robust watermarking is a mechanism to create a Communication channel that is multiplexed into original content.
