The present invention relates to a user authentication method and system using biometric information and a mobile communication terminal for transmitting authentication information using biometric information. More specifically, when the user inputs the biometric information into the mobile communication terminal, the biometric information is stored in the mobile communication terminal and the biometric information is compared with the biometric information. The stored authentication information is transmitted to an authentication server through an additional service server, and the authentication server relates to a system and method for processing authentication for authentication information and a mobile communication terminal for transmitting authentication information using biometric information.
As computer, electronic, and communication technologies have made rapid progress, various wireless communication services using a wireless network have been provided. Accordingly, the mobile communication service provided by the mobile communication system using the wireless communication network has been developed into a multimedia communication service that transmits data such as circuit data, packet data, as well as voice service. An additional service is provided through a mobile communication system, that is, a mobile communication network.
Among such additional services, an electronic commerce service including an electronic banking and shopping mall service using a wireless communication network performs a user authentication procedure to identify a user's identity.
As a conventional user authentication technology, a character input method of ID and password is most widely used, and an electronic signature using a public key infrastructure or a public key encryption technology is used to improve security than ID and password methods. User authentication is performed through. Recently, a user authentication technique using a mobile communication terminal number or a means using an encryption chip embedded in a mobile communication terminal and a user authentication technique using biometric information of a user have been applied to a mobile communication system.
Such user authentication technology using biometric information includes face recognition, fingerprint recognition, iris or retina recognition, and when a user first joins an e-commerce service, the authentication server receives the user's biometric information and receives the user's standard biometric information. When using the electronic commerce service, the user inputs biometric information to the mobile communication terminal, and the mobile communication terminal transmits the input biometric information input from the user to the authentication server. Receiving the input biometric information, the authentication server compares the pre-stored user's standard biometric information with the input biometric information and allows the user to use the electronic commerce service if the standard biometric information and the input biometric information match.
The biometric methods described above have not yet overcome practical problems in implementing user authentication technology for a large number of users connected to a network. The biggest problem among them is that the biometric information received from the mobile communication terminal is an image data format having a large capacity. Therefore, when a large number of users request user authentication using biometric information from the authentication server, the authentication server is overloaded. As a result, the user authentication processing speed is lowered as a whole and a large data transmission load is required because a large amount of authentication data must be transmitted. In addition, when the number of users who use user authentication using biometric information increases, the authentication server needs to upgrade the capacity of the storage device to store the standard biometric information of the increased user.
On the other hand, when performing the user authentication with the conventional authentication information using the ID and password method of the character input method, because the user must enter the conventional authentication information directly to the mobile communication terminal, their conventional authentication information is exposed to the people around There is this.
In order to solve the above-described problem, when the user inputs the biometric information to the mobile communication terminal, the standard biometric information and the input biometric information are matched by comparing the biometric information previously stored in the mobile communication terminal with the input biometric information. In this case, the authentication information pre-stored in the mobile communication terminal is transmitted to the authentication server through the additional service server, and the authentication server transmits the authentication information by using the biometric information and a system and method for processing authentication on the authentication information. The purpose is to provide.
In order to achieve the above object, the present invention provides an authentication method using biometric information in a system including an additional service server, an integrated authentication server, an integrated authentication DB (Data Base), a mobile communication network, and a mobile communication terminal. Selecting a user authentication for accessing the additional service server to use the additional service by the mobile communication terminal; (b) requesting the additional service server to input user authentication information to the mobile communication terminal; (c) receiving, by the mobile communication terminal which is requested to input the authentication information, biometric information from the user and comparing the biometric information with standard biometric information of the user previously stored in the mobile communication terminal; (d) transmitting integrated authentication information previously stored in the mobile communication terminal to the additional service server when the input biometric information, which is the biometric information input to the mobile communication terminal, matches the standard biometric information; (e) the additional service server receiving the integrated authentication information transmitting the integrated authentication information to the integrated authentication server; (f) the integrated authentication server comparing the integrated authentication information with standard authentication information of the user stored in the integrated authentication DB; And (g) processing the user authentication when the integrated authentication information and the standard authentication information coincide with each other.
