Access Control for Middleware in RFID Systems

Radio frequency identification (RFID) is an emerging technology which brings enormous productivity benefits in applications where objects have to be identified automatically. Middleware plays a key role to deliver tag data in real time, which resides between readers and enterprise applications in RFID systems. Therefore, the middleware should be controlled by proper authorization policy. In this paper, we propose access control policy which can be applied to RFID middleware. This policy can express range of tag data to be provided, readers to be accessed, commands to request, and notification addresses to receive report from middleware
