ABSTRACT
Steganalysis is the scientific art of defeating the steganographic goal [3,4]. As stated before, the steganographic goal is not to prevent an adversary from decoding a hidden message, but to prevent an adversary from suspecting the existence of hidden data [3]. us, when using any steganographic technique, if suspicion is raised the goal of steganography is defeated regardless of whether or not a plain text message is revealed [4,23]. As such, the aim of this chapter is to show the resilience to possible attacks of the several methodologies that are based on the Nostega paradigm. It is assumed that an adversary will perform all possible investigations. In addition, the adversary is also aware of Nostega, as a public paradigm, but he does not know the details of the Nostega-based system that the sender and recipient employ for their covert communication.
