An effective communication model for collaborative commerce of Web-based surveillance services

We design and implement a Web-based information system for providing remote surveillance services. The surveillance data can be treated as a kind of digitized product in e-market. By collaborating different value-added services with the same surveillance data, diverse surveillance applications can be introduced. For example, by collaborating with companies (i.e. virtual enterprises) that supply Web-services such as face-recognition, moving object tracking and abandoned object identification, we can create new and diverse digitized products for supporting security systems, intelligent transportation system (ITS) and biometric system in airports, parking lots and offices. For supporting ubiquitous services, we collaborate with the auto-dialup service of PSTN networks (B2B e-commerce) to send messages to the subscribed user (B2C e-commerce) through his/her phone, pager or fax machine. By collaborating the media streaming service, users can watch live/recorded surveillance videos immediately through wired/wireless Web-devices. To reduce network workload, we apply multicast communication for the surveillance video delivery. Furthermore, an effect and efficient motion detection method is proposed to reduce redundant traffic and storage. Experiments show that our proposed schemes can help the system remit the performance penalty from network congestion.
