Using Mobile Device to Design a Secure Transaction

In recent years, RFID (radio-frequency identification) system has widely used owing to its convenient and efficiency in many applications. In this paper, we propose a novel scheme that the market membership can use the mobile reader to query products information and make a secure transaction through cash register. There also can use the accumulated digital coupon to redeem prizes with the server. Moreover, in order to achieve the mutual authentication, we involve the fingerprint biometrics, related cryptology and hash function mechanism to ensure the security of the transmission messages. Our proposed scheme also can resist several attacks and ensure a secure transaction.
