碩士 === 逢甲大學 === 資訊工程所 === 99 === RCM(Reversible contrast mapping) and LSB data hiding(Least significant bit) are two of the most popular data hiding techniques, they have different characteristics and advantages. However, both are subject to steganalysis. In this work we propose a new scheme to counter measure the steganalysis. By employing simple arithmetic operations, we provide ways to foil the steganalysis, to improve these two methods based on not to increase the burden and destroy the secret. The experimental results show that the proposed scheme successfully breaks the camouflage medias unusual features, and both the embedding measure and confidentiality are not worse than the original ways.
