N2 - Reversible data hiding in the encrypted domain is an emerging technology because of the privacy-preserving requirements from cloud data management. In this paper, a reversible data hiding scheme in encrypted H.264/AVC video streams is proposed. During H.264/AVC encoding, the intra-prediction mode (IPM), motion vector difference (MVD), and residue coefficients' signs are encrypted using a standard stream cipher. Then, the data-hider, who does not know the original video content, may reversibly embed secret data into the encrypted H.264/AVC video based on histogram-shifting of residue coefficients. With an encrypted video containing hidden data, data extraction can be carried out either in encrypted or decrypted domain. In addition, real reversibility is realized, that is, data extraction and video recovery are free of any error. Experimental results demonstrate the feasibility and efficiency of the proposed scheme.
