LSB matching steganalysis techniques detect the existence of secret messages embedded by LSB matching steganorgaphy in digital media. This study presents a survey of LSB matching steganalysis methods for digital images. Firstly, study described the structure of LSB matching steganalysis, which includes three parts: LSB matching steganography, detectors for LSB matching and the evaluation methodology. Secondly, study classified the existing detection algorithms into two categories according to the fact that the main contribution of the algorithm...
