The RFID middleware system supporting context-aware access control service

Recently, the RFID (radio frequency identification) technology attracts the world market attention as essential technology for ubiquitous environment realization. The RFID market has been extended focusing on RFID software like as high-valued e-business applications, RFID middleware and related development tools. However, due to the high sensitivity of data and service transaction within the RFID network, security considerations must be addressed. In order to guarantee trusted e-business based on RFID technology, we propose a security enhanced RFID middleware system. That is, we descript architecture and technique of middleware support context-aware access control service. Our proposals are compliant with EPCglobal ALE (application level events), standard interface for middleware and its clients. We illustrate the security enhanced middleware architecture and operation sequence for access control service with description
