Secure Mobile RFID system against privacy and security problems

Radio frequency identification (RFID) systems based on EPC (electronic product code) network environment automatically identify tagged objects, using RF signals without direct contact. The RFID system will replace the Bar-code system, because it provides storage ability and contactless property. Recently, researchers introduced the mobile RFID system, which integrates a mobile system with a RFID technique and provides new services to users. However, the feature for obtaining information of objects using RF signals causes personal privacy problems such as information leakage and traceability. In this paper, we propose a privacy protection scheme suitable to mobile RFID systems. Our scheme is secure against threats such as impersonation, information leakage, and traceability.
