Secure surveillance using SMIL

摘要

The role of multimedia and user interactivity has increased in recent years. User interaction is an important component of emerging multimedia systems, and the methods of interaction will become increasingly complex as they are being used in more diverse applications. One such application is surveillance, both in the civil as well as the military domain. The real-time three-dimensional stereovision adds sense of immersion and makes imagery closer to those produced by our own eyes as described in [1]. In our paper we propose a framework to capture an unfolding scenario as it happens and transmit the captured media using SMIL securely to a group of users with varied privileges. Apart form enforcing privileged access our model also ensures integrity of the content in transit through encryption.
