A New Method to Protect Privacy in RFID based on Object Deputy model

Recently RFID has been applied in many different areas such as supplying chain management and inventory control. While the RFID system has many advantages, however, it may create new problems to the user´s privacy. In this paper, we propose a new architecture of RFID system which designs a special data privacy protection module in traditional RFID system for protecting users´ privacy. And the new privacy protection module is based on Object Deputy Model .Simulation and Performance analysis indicates that: the new method is safer and has higher throughput compared to the Randomized Hash-lock protocol.
