In this paper propose a new method for the real-time hiding of information used in compressed video bitstreams. This method is based on the real-time hiding of information in audio steganography. This method of steganography is very similar to the two discussions of image steganography and video steganography. A new compressed video secure steganography(CVSS) algorithm is proposed. In this algorithm, embedding and detection operations are both executed entirely in the compressed domain, with no need for the decompression process. The new criteria employing statistical invisibility of contiguous frames is used to adjust the embedding strategy and capacity, which increases the security of proposed algorithm. Therefore, the collusion resistant properties are obtained. Video steganalysis with closed loop feedback manner is design as a checker to find out obvious bugs.
