Description: RS and Chi-square analyses are powerful steganalytic techniques for detecting the presence of secret information embedded in the least-significant-bit(LSB) plane of digital images. This paper describes an improved LSB steganographic scheme that can effectively resist both RS and Chi-square analyses without sacrificing perceptual quality of the cover image. In the described steganographic technique, a pair of mutually complementary mappings, F1 and F-1, is used, leading to a balanced behavior of ...
