Through dynamic compensation of pixel values of the LSB embedded image, this paper presents a novel LSB steganography method against RS, a powerful LSB steganalysis technique proposed by Fridrich with high precision. Firstly, this method embeds message in the LSB plane of the carrier image randomly, then make a dynamic compensation on the steg-image. Theoretic analysis and experimental results show that even the embedding rate is near 100% in this steg-image, such dynamic compensation can make RS steganalysis get a very small estimate value close to 0, which will cause an incorrect judgement. Moreover, the selection parameters of the compensation can be used as a part of the steganography system key to improve the steganography system's security, and the experimental results also indicate that this method is efficient to defeat some other LSB steganalysis methods
