A Review on Video Encryption Technologies

Abstract: Security and privacy are important things in video communication for that reason from last few years different video encryption methods have applied to secure video transmission. large number of multimedia encryption schemes have been proposed and some of them are used in real products, cryptanalytic work has shown the existence of security problems and other weaknesses in most of the proposed multimedia encryption schemes .This review paper describe different video encryption method also give the comparison between encryption methods with respect not only to their encryption speed but also their security level and stream size. A trade-off between quality of video streaming and choice of encryption technologies is shown here. Flexibility, efficiency, security and privacy are the challenges for the design.

Keywords: Video encryption, video transmission, stream size.
