An empirical study of secure MPEG video transmissions

Abstract

MPEG (Moving Pictures Expert Group) is an industrial standard for video processing and is widely used in multimedia applications in the Internet. However, no security provision is specified in the standard. We conducted an experimental study of previously proposed selective encryption schemes for MPEG video security. This study showed that these methods are inadequate for sensitive applications. We discuss the tradeoffs between levels of security and computational and compression efficiency.
