Abstract

This paper presents a new dynamical RS steganalysis algorithm[1] to detect the least significant bit (LSB) steganography. The novel algorithm dynamically selects an appropriate mask for each image to eliminate the initial error. Experimental results show that our algorithm is more accurate than the conventional RS method. Meanwhile, the theoretical deduction of the length-estimate equation of RS method is given.
