Ubiquitous video surveillance service with secure forwarding agents

Video surveillance systems have been playing an important role to protect lives and assets of individuals, enterprises and governments for decades. Due to the prevalence of wired and wireless access to Internet, ubiquitous video surveillance (UVS) service could be fulfilled to provide diversified surveillance services. In this paper, forwarding agents of multicast agent (MA) and super agent (SA) with security protection via Diffie-Hellman key exchange algorithm are proposed for UVS, so forwarding agents can provide surveillance video streaming service with scalability, ubiquity and privacy on the public Internet. FEC is also applied for reliable surveillance-video multicast to preserve the playback quality of UVS both on Internet and 802.11 Wireless-LAN. The experimental results from the deployed UVS test-bed with Wi-Fi Internet access demonstrate the effectiveness of the proposed schemes for UVS.
