For accessing Internet, a reusable password method is frequently used because of its simplicity. This reusable password method is very vulnerable. In recent years, with the explosive growth of the Internet user, user passwords are often incorrect handled and this attestation system is very dangerous. To solve these vulnerability problems of the attestation system, the one-time password, biometric system, and other methods using IC or LSI chips have been developed to build more complex authentication systems. But, still remain many problems such as system complexity and certification costs. In order to provide a low-cost and simple user attestation method, in our previous work, we proposed a method with strong authentication by using digital camera of cellular phone. But, this method used 2D color code, thus there are some process costs such as create and decode 2D color code. In this paper, we present an improved attestation system using a cellular phone and 2D color code. The efficiency of the proposed attestation method is confirmed by an experimental prototype system.
