Abstract :
With the rapid development of steganography, steganalysis has advanced quickly. Battle between steganography and steganalysis has become an important issue in information security. Aiming at a commonly used cover media, i.e., digital image, this article reviews steganography and steganalysis based on digital image. Concept and principle of steganography and steganalysis are illustrated. Spatial domain and transform domain embedding methods are generalized. And the recent advances in steganalysis are recapitulated. Then the performance specification of image steganography is discussed. Finally some new trend and problems faced are also discussed.
