Abstract

Steganography is the process of hiding information in cover media to obtain the stego media, such that the cover media is perceived not to have any embedded message for its unintended recipients. Steganalysis is the mechanism of detecting the presence of hidden information in the stego media and it can lead to the prevention of disastrous security incidents. The three common forms of cover media used in Steganography are Image, Audio and Video. Only few algorithms are available for audio and video steganalysis and there is no comprehensive survey available for the same. The high-level contribution of this paper is a critical review of the algorithms available for audio and video steganalysis. We observe that each of these two cover media has its own special attributes and steganalysis algorithms developed for one category are not applicable to the other. We anticipate that this paper will serve as a launch pad for investigators interested in audio and/or video steganalysis research.
