RFID, Radio Frequency Identification, is an emerging technology in the world of automatic identification. It uses RF signal for gathering information of tags, which can be attached or embedded to goods such as consumer electronics, items in supermarkets, automobile's parts. It may make our life more comfortable and more ubiquitous, but it may make us, on the other hand, more nervous. This is because that there are some privacy problems in RFID system. More comfortable automatic identifications would lead to more disclosure of our private life. This reason rushed many researches results related to security and privacy in RFID system. However, we cannot choose anything among them for applying to the current RFID system. Most of them require either of high-cost hardware specification or giving up potential convenience of consumers. In this paper, we propose a simple privacy protection scheme that can be used for the current existing RFID system such as ISO 18000-6 type C. We modify this standard tag identification protocol slightly and introduce a light-weight proxy device for privacy enhancing.
