An Efficient Video Steganography Scheme for Data Protection in H.265/HEVC

An efficient and novelty video steganography scheme with adopting averting intra prediction distortion drift technique is proposed in this paper for the enhanced protection of crucial data related to H.265/HEVC digital video. With adoption of intra prediction modes selection and DCT/DST coefficients correlation, the intra prediction distortion drift can be totally prevented in intra frame (I frame). With adoption of selection of prediction patterns of multiple adjacent prediction blocks, the intra prediction distortion drift in inter frames (B frame or P frame) can be totally prevented. Compared to the previous related works, the proposed scheme applied the averting intra prediction distortion drift technique not only intra but also inter frames, and further improve the visual quality (imperceptibility) of carrier video about H.265/HEVC. Moreover, larger embedding capacity can also be achieved rather than embedding only manipulated on I frames. The experimental results have been proven the superiority of efficiency and performance about the proposed scheme.
