Image LSB Steganalysis via Improved RS and DIH Methods

摘要：

Two improved detection algorithms of image LSB (least significant bit) steganography are proposed. One algorithm is an improvement of RS method, it dynamically selects an appropriate mask for each doubtful image to eliminate the initial bias. The other algorithm is an improvement of DIH method, it reconstructs a more reliable equation to estimate the embedding ratio of stego-image. Experimental results show both algorithms are more accurate and more reliable than the conventional RS and DIH methods.
