Abstract : Steganography is the art of hiding information in ways that avert the revealing of hiding messages. This paper proposes a new Compressed Video Steganographic scheme. In this algorithm, data hiding operations are executed entirely in the compressed domain. Here data are embedded in the macro blocks of I frame with maximum scene change and in block of P and B frames with maximum magnitude of motion vectors. To enlarge the capacity of the hidden secret information and to provide an imperceptible stego-image for human vision, a novel steganographic approach called tri-way pixel-value differencing (TPVD) is used for embedding. In this scheme all the processes are defined and executed in the compressed domain. Though decompression is not required. Experimental results demonstrate that the proposed algorithm has high imperceptibility and capacity.
