Secure Real Time Remote Video Monitoring System

摘要

Video has been an important media for entertainment and communication for many years. Initially video was captured and transmitted in analog form. The digitization of video was done due to the development of computers and digital integrated circuits. The digital video enabled a revolution in the compression and communication of video. With the growth of the multimedia technology video streaming technology is gaining importance. Streaming is simply a technique for transferring data such that it can be processed as a steady and continuous stream. The file is sent to the end user in a (more or less) constant stream. With streaming, the end user can start watching the file almost as soon as it begins downloading. Security becomes a key problem to be handled when valuable multimedia data are travelling over the network. As security of data over the network is a burning issue and dominates the communication systems today, in this paper we present a real time video monitoring security system, named as Secure Video Monitoring System (SVMS) with authentication and selective encryption to securely transfer the valuable multimedia video streams over the un-trusted network. The process of authentication is done by allowing the network access to only authenticated users, data is compressed and decompressed using compression technology. This system provides security by selectively encrypting the streaming data which is send over the network. It also provides video on demand (VOD).
