Abstract: The upcoming H.264/MPEG-4 AVC video compression standard promises a significant improvement over all previous video compression standards. In terms of coding efficiency, the new standard is expected to provide at least 2x compression improvement over the best previous standards and substantial perceptual quality im-provements over both MPEG-2 and MPEG-4. Video encryption often requires that the scheme be time efficient to meet the requirement of real time and format compliance. It is not practical to encrypt the whole compressed video bitstream like what the traditional ciphers do because of the following two constraints, i.e., format compliance and computational cost. Alternatively, only a fraction of video data is encrypted to improve the efficiency while still achieving adequate security. The key issue is then how to select the sensitive data to encrypt. Iit is reasonable to encrypt both spatial information (IPMand residual data) and motion information (MVD) during H.264/AVC en-coding.
