Abstract: Steganography is the science of invisible communications over an innocuous cover medium. Most steganographic systems defeat both visual and first order statistical attacks however they offer only low capacity embedding. In this paper, a new steganographic system is introduced for message embedding by inverting the LSB of DCT coefficients of JPEG image. This algorithm offers high capacity compared to existing steganographic system.
