On the security of multimedia video information

Abstract

The distribution of multimedia information has many applications such as video-on-demand, video conferencing, and video broadcast. It is very challenging to maintain the high quality content delivery and in the mean time to preserve the digital rights management. In the past few years, many video encryption algorithms have been proposed, but the security of the algorithms have not been adequately analyzed. In this paper several methods were proposed to evaluate the security of encrypted MPEG video. Our Take, Skip, and Permute (ISP) solutions to achieve reliable MPEG encryption are presented.
