Steganography is used to hide the occurrence of communication. Discovering and rendering useless such covert message is an art of Steganalysis. A popular Steganalysis technique is Difference Image Histogram (DIH), proposed by Zhang, aimed at LSB steganography. This algorithm can not only detect the existence of hidden messages embedded using sequential or random LSB replacement in images reliably, but also estimate the amount of hidden messages exactly.
In this paper a number of stego images are created by varying the percentage of embedding i. e. from 0% to 100% of total number of pixels, total number of ones in the LSB plane and total number of zeros in the LSB plane. The Difference Image Histogram algorithm is applied to all these images. And a result is drawn as to exactly when and why the algorithm fails. A steganographic technique to escape Difference Image Histogram Steganalysis is then presented.
