Abstract

This chapter provides critical analysis of current state-of-the-art in steganography. First part of the this chapter provides the classification of steganography based on the underlying information hiding methodology used and covert-channel type, and desired features of the information hiding used for covert communication. This chapter also discusses various known steganalysis techniques developed to counteract the covert-communication and highlights limitations of existing steganographic techniques. Performance analysis of commonly used shareware/freeware steganographic tools and steganalysis tools is also provided in this chapter. Some open problems in covert-communication are also discussed.
