Steganalysis is the new research area that is appeared before the late 1990s. It is a technique that is used for detecting the presence of hidden information in some cover media. Normally steganalysis is a challenging task when the pattern of the hidden information is unknown to the steganalysts. To deal with this, bit plane analysis is proposed in this paper. Bit planes of cover and stego images are analyzed by computing the difference of corresponding 8 bit planes so that one can clearly see hidden information with varying densities. Black regions of the image represent the value that is similar for both the images and the white regions represent hidden secret message.
