Abstract

In multimedia conferencing systems the need for confidentiality gains in importance. This goal can be achieved by encryption. In real-time video processing systems there is a special need for partial data encryption. Existing methods and their weaknesses are investigated. We present a new approach for partial encryption of video data, which allows a security level of nearly every granularity. It can be applied to all JPEG-based video compression methods
