Steganalysis Using Statistical Properties of Digital Signal, M.Sc. Thesis Sharif University of Technology ; Ghaemmaghami, Shahrokh (Supervisor) ; Eghlidos, Taraneh (Supervisor)
Abstract
Steganography is the art and technique of concealing secret message in ordinary data cover, transmitted over a public channel, in a way that eavesdroppers, as well as the channel users, cannot detect the presence of the secret message. However, steganalysis tries to detect this type of covert communication using some effective analysis techniques. Steganalysis is often based on statistical properties of the suspicious signal that are expected to change due to the message embedding process. Secret message (which mostly is a set of pseudo-random bits because of cryptography) affects the statistical features of the cover signal. So far, many steganalysis techniques have been reported that are...
