This paper proposes a new video steganography algorithm based on the differences of motion vector components for H.264/AVC video compression standard.In view of the characteristics of Human Visual System(HVS),the algorithm filters the motion vectors which HVS is less sensitive to.It uses the difference between the chosen motion vectors components to control the operating position,and embeds secret message in the component.During embedding,only to modify the component with larger absolute value,and the operation is symmetric,so that the impact of the carrier's statistical properties is reduced.Theoretical analysis and experimental results show that the algorithm obtains the higher carrier utilization and embedding efficiency,and achieves the requirements of covert communication about the invisibility and capacity.
