In recent years, with the development of network technology and the popularity of e-commerce, online banking had a rapidly development and the users have being constantly increased. Online banking transactions hit the new record again and again. But at the same time, unsafe events is also exists in online banking. Many customers of bank were not willing to use online banking by now, most of them consider that online banking also has security risk.Aspects of online banking transactions can be divided into three components: client side authentication, data transmission process and server management. For the data transmission process, the bankers usually use SSL (Secure Socket Layer) technology, the link are still relatively safe, Online banking server with multiple firewalls and intrusion detection system protection, make this link more secure. In the last years, it appeared some thefts to online banking, the overwhelming majority of them happened during the client link of online banking transactions. From this, the weakest link of online banking is the part of the client side authentication.As the first line of defense of the online banking transaction system, identity authentication has a vital role. But with the development of network technology, the way which hackers attack client side of the Online Banking become more and more, and the single authentication method can not meet the current needs of the users of the online banking. In this regard, this paper made appropriate technical analysis and comparison for some common online banking authentication methods, and proposed a method of identity Certification system for the online banking based on fingerprint recognition and PKI Technology with USB Key. The uniqueness of fingerprints, and not easy to lose and PKI has a very good protection mechanisms for private key, and the encryption technology of USB Key so that the security of online banking authentication is greatly enhanced.The paper studied fingerprint recognition algorithm accordingly, but also some algorithm have been improved in the process of fingerprint identification in order to improve the recognition rate. The project stored fingerprint templates in the USB Key, and used the method of one-to-one comparison, which improved efficiency and security of matching fingerprint. Only through the fingerprint verification, could it make the next operation, it really implemented authentication for the users.The system mainly completed the scheme of customers¡¯registration and authentication, realizing the fingerprints¡¯registration and identification. And simulated user authentication of the entire process, made an analysis for the security of online banking authentication. Finally, the paper made an analysis for the future prospect of the authentication method in the practical application.
