  Abstract

The low-cost RFID system is expected to be widely used in the ubiquitous computing environment as an intelligent device. Although RFID systems have several advantages, they may create new threats to users' privacy. In this paper, a traceable and unlinkable RFID system called "Fair EPC System" is proposed for low-cost RFID tags. The proposed system enables the protection of users' privacy from unwanted scanning, and it is traceable to the tag by authorized administrators when necessary. The proposed system has some advantages, (1) eliminating any danger of exposing users' information via tag tracking through the cooperation between readers or back-end databases, (2) enabling the tracking of real senal number of the tag only through the cooperation of authorized administrators using a cryptographic secret sharing scheme, and (3) providing the efficiency of the proposed system reduce the computational workloads of back-end databases.
