An Efficient Video Steganography Algorithm Based on Sub-Macroblock Partition for H.264/AVC

In this paper, a simple video steganography algorithm based on the tree structured motion compensation of the H.264 video compression standard is proposed. In the proposed method, the head data of macroblock in P/B-frames was used as a cover, the 8x8 partition modes which represent the detailed areas are selected, and information hiding is implemented by modifying the partition modes of the sub-macroblock. Experiments are designed to prove the feasibility of the proposed scheme by using different kinds of test videos. Simulation results show that, in our scheme, a high data hiding rate is obtained with a little increase on bit rate, and it also has the characteristics of high computational efficiency and imperceptibility.
