Classification of steganalysis techniques: A study

Steganography is the art of secret communication and steganalysis is the art of detecting the hidden messages embedded in digital media using steganography. Both steganography and steganalysis have received a great deal of attention from law enforcement and the media. In the past years many powerful and robust methods of steganography and steganalysis have been reported in the literature. In this paper, we classify and give an account of the various approaches that have been proposed for steganalysis. Some promising methods for statistical steganalysis have also been identified.
