"The good, the bad and the ugly": Evaluation of wi-fi steganography

In this paper we propose a new method for the evaluation of network steganography algorithms based on the new concept of âthe moving observerâ. We considered three levels of undetectability named: âgoodâ, âbadâ, and âuglyâ. To illustrate this method we chose Wi-Fi steganography as a solidfamily of information hiding protocols. We present the state of the art in this area covering well-known hiding techniques for 802.11 networks. âThe moving observerâ approach could help not only in the evaluation of steganographic algorithms, but also might be a starting point fora new detection system of network steganography. The concept of a new detection system, called MoveSteg, is explained in detail
