Reversible Data Hiding Scheme Based On H.264/AVC without Distortion Drift

There is greater possibility that reversible video data hiding scheme causes more distortions than reversible image data hiding. In H.264/AVC video streams, intraframe distortion drift is a big problem in data hiding. This paper proposes a novel readable reversible data hiding scheme in H.264/AVC which can avert the distortion drift. We embed data into the quantized discrete cosine transform (DCT) coefficients of I frames which meet the directions of intra-frame prediction, and the directions of intra-frame prediction are utilized to avert the distortion drift. It is proved analytically and shown experimentally that the proposed algorithm can achieve high embedding capacity and low visual distortion, and the original compressed video can be recovered exactly after the hidden data, in addition, the proposed system is fast and simple. Performance comparisons with other existing schemes are provided to demonstrate the superiority of the proposed scheme.
