Application Of Payment Authentication System Based On Fingerprint Recognition Technology

With the development of the Internet and the popularity of mobile phones, online shopping continues to develop, mobile payment came into being and more and more recognized by the public. Mobile payment security risks exist, the current system in order to improve security,forcing users to remember a large number of passwords. This method not only can not meet the needs of the user's convenience and usability, but also can not achieve the unique binding of user identity.With regard to the security of the mobile payment system,there are two problems to be solved: the security of the customer information transmission and storage management,on the other hand is the customer's identity authentication. By analyzing the advantages and disadvantages of different encryption techniques, the ECC algorithm is used to distribute the symmetric key, and the AES algorithm is used to encrypt the customer information to ensure its security. There are a variety of authentication technologies for customer authentication. This paper introduces the WKPI authentication technology and biometric technology. Taking into account the advantages and disadvantages of a variety of technical means, in order to adapt to the use of mobile devices, the paper finally selects WKPI authentication technology and fingerprint identification technology to achieve the purpose of user and system authentication. In this paper, the fingerprint recognition is introduced in detail, including the process of fingerprint identification, algorithm, etc., some of the steps of the algorithm is optimized, but also the fingerprint identification of the MATLAB implementation.In this paper, different combinations of characters instead of doing the payment password used as fingerprint payment password but another way to the traditional combination of characters, the fingerprint recognition of the identity of the user that has high reliability. According to the actual situation, the system is tested, and the feasibility,usability and security of the system are analyzed.
