Secure Steganography in Compressed Video Bitstreams

A new compressed video secure steganography (CVSS) algorithm is proposed. In the 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. Experimental results showed this scheme can be applied on compressed video steganography with high security properties.
