Secure real time remote video monitoring using selective encryption

Advances in video technology and computing gave a way to the growth for applications and devices in real time video monitoring. Video data containing real and accurate information is being used greatly by monitoring system. Monitoring systems are widely used at public institutions, banks, corporate and laboratories where security is very an important aspect. There is a growing need to visually monitor an area from a remote location using a video camera or web cam. The proliferation of web cams and the increasing use of streaming media have improved the ability of users to communicate with each other, to be entertained and to monitor or perform surveillance. Along with this the security of data travelling over network becomes essential. In this paper we propose a selective encryption based video monitoring system (SEVMS), which securely transfer data over untrusted nefwork. The live video data transferred over network is compressed and then selectively encrypted. Since the live video is selectively encrypted any unauthenticated person will not be able to view it. The system also provides facility of video on demand (VOD).
