Abstract: This paper analyzes an IPIDs-based protocol steganography, and gives the construction method of a statistical variable for steganalysis. And an estimate approach of stego data-package in analysis window is proposed. A modified strategy is presented to enhance the algorithm’s security. Experimental results indicate the efficiency of the proposed method.
