RETRACTED: A Novel Video Reversible Data Hiding Algorithm Using Motion Vector for HEVC (Retracted Article)

Steganography is the art to hide secret information behind video, which should be closely related with video coding standard. As the newest video coding standard, high efficiency video coding (HEVC) has great potential as a new information hiding carrier. This paper proposes a reversible information hiding algorithm based on motion vector for HEVC video. First, The algorithm of this paper chooses information hiding points by assigning different thresholds to different coding unit types. Then the modulation vector is introduced, and the secret embedding is realized on the basis of the inner product of f the motion vector difference and the modulation vector. Experimental results show that the proposed method makes it possible to maintain the visual perceived quality of the secret embedded video. And has higher capacity than other existing schemes. All the extracted information can be recovered without loss of the original compressed video carrier which achieves the reversibility of information hiding.
