This paper presents the design of a novel high-secure wireless video surveillance system. The system is based on the 802.11g ad-hoc wireless infrastructure; and the Intel IXP425 network processors are used as the basic processing unit. A media-dependant video encryption scheme, including reliable data embedding technique and real-time video encryption algorithm, has been implemented for the system to work in an open and insecure wireless environment. Our system offers several unique advantages: (1) it provides high security guarantee; (2) it does not require expensive access points/routers; (3) it can be readily deployed since it is built on top of existing wireless ad-hoc infrastructure; (4) it is robust in the presence of adaptive mechanism and error-prone channel.
