Privacy Enhanced RFID System based Location Tracking System with TTP

RFID system is now becoming widely accepted for many EPC Network applications. However, RFID system has some privacy problems. Especially, the location based services have been proactive in adopting RFID in the areas, and location based services are relying on the availability of the user location information to provide specific information. In this paper, we propose a system for missing child location tracking in the EPC Network application. The proposed system improves the security and privacy of existing applications while keeping procedures already holding by industrial applications. The system can protect users privacy and provide location tracking of the tag if necessary.
