Abstract:Radio Frequency Identification (RFID) as a new automated identification technology has become popular with the supply chain and retail business. However, the widespread employment of RFID tags may bring new threats to the consumers' privacy, due to the powerful tracking capability of the tags. There are several important technical points when constructing an RFID scheme. What is particularly important is the issue of consumers' privacy and security of tag information. Low cost implementation is another one. To address these issues, the requirements and restrictions of RFID systems were discussed and clarified in this paper, and the features and issues pertinent to several current RFID schemes were analyzed. Finally, a simple secure mode tag which adopted a low cost hash chain mechanism to enhance the consumers' privacy was proposed.
Keywords:Radio Frequency Identification(RFID)  privacy  security  privacy enhancement technology
