Data hiding has drawn extensive interests in the past decade. The availability of various data hiding algorithms, together prevailing digital multimedia and transportation network, in particular Internet, has made covert communications a reality in this digital age. In other words, modern steganography has been feasible and can be carried out rather efficiently. As a result, the effective way to detect covert communications, i.e., the first and very important step of steganalysis is called for. The applications of steganalysis include combating illegal distribution of children pornography that is embedded into normal images and videos and intercepting criminal covert communications among terrorists. In addition, the steganalysis can serve as an effective way to evaluate the security performance of various steganographic techniques. The relationship between steganography and steganalysis is just like that between missile and anti-missile, i.e., the measure and countermeasure. This tutorial is to present to the audience the fundamental concepts, the most typical algorithms and the future research issues in the area of steganography and steganalysis. Specifically, (I) The basic concepts of steganography and steganalysis, their meaning and applications will be introduced. (II) The typical modern steganographic techniques such as Outguess, F5 and MB (model-based) will be described. (III) In addition to some well-known steganalysis schemes, the most powerful prior-art of universal steganalysis scheme and the most powerful prior-art of steganalysis scheme aiming at detection of steganographic techniques designed for JPEG images will be presented. The newly developed steganalysis schemes which outperform the above-mentioned prior-arts by a significant margin will be presented and analyzed. (IV) Finally, the future research will be discussed.
