Towards developing secure video surveillance systems over IP

摘要

A framework of three attributes for video surveillance systems is underlined: availability, accessibility and authenticity. Under this framework, a scenario in which surveillance cameras can be accessed by remote devices, such as mobile phones, PDAs, over IP is addressed. Some security drawbacks of an off-the-shelf product are depicted and a new solution is proposed which uses cryptographic authentication for the broadcasted images. The proposed application is implemented in Java and can run on any device from standard computers to mobile phones. Also, some experimental results are presented for the case when a mobile phone is used as a receiver, this case being relevant as the device is the potential receiver with the most constrained computational resources.
