Steganography techniques

Dragoş Dumitrescu and Ioan-Mihail Stan and Emil Simion

Abstract: As cryptography is the standard way of ensuring privacy, integrity and confidentiality of a public channel, steganography steps in to provide even stronger assumptions. Thus, in the case of cryptology, an attacker cannot obtain information about the payload while inspecting its encrypted content. In the case of steganography, one cannot prove the existence of the covert communication itself. The main purpose of the current paper is to provide insights into some of the existing techniques in steganography. A comparison between the performances of several steganography algorithms is accomplished, with focus on the metrics that characterize a steganography technique.
