Abstract :
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 issimilar for both the images and the white regions
represent hidden secret message.
