no. 1 example

[0023] Example 1 describes a situation where a particular user uses a particular client for biometric authentication. Although the biometric authentication system is constituted by connecting the client and the server via a network in Example 1, for example, a cellular phone, a PDA (Personal Digital Assistant), etc. may be used instead of the client.

[0024] Hardware composition diagram:

[0025] 1 and 2 are block diagrams schematically showing examples of hardware configurations of a client 0 and a server 100 constituting a biometric authentication system.

[0026] The client 0 is configured by connecting the following parts via a bus 18: a CPU (Central Processing Unit) 2 that executes calculation processing, an operation section 4 that receives data input, a display section 6 that displays information, and a ROM (Read Only Memory) that stores programs. ) 8, RAM (Random Access Memory) 10 for executing programs and / or storing data, input device 12 for reading user's biometri...

[0104] The second embodiment describes a case where an indeterminate number of users perform biometric authentication using a specific client. Since the hardware configuration of this biometric authentication system is the same as that of the biometric authentication system described with reference to FIGS. 1 and 2 in Example 1, description thereof is omitted.

[0105] Functional Block Diagram (Part 3):

[0106] FIG. 8 is a functional block diagram schematically showing an example of a creation function with reference to biometric data. This reference biometric data creation function is composed of a client 0 and a server 100 . The reference biometric data creation function of client 0 is composed of biometric information input means 202, biometric data creation means 204, reference biometric data creation means 206, group information selection / determination means 222, group information storage means 224, reference biometric data The data overlap notifying means 226, the reg...

Abstract

A biological authentication system which has a high authentication success rate and a low improper authentication rate and does not inconvenience users is proposed. In a server connected to a client, which creates biological data of a user to be authenticated, over a network and performs the authentication determination on the user, user authentication is performed by comparing identification information stored in the client and the identification information of reference biological data if multiple pieces of reference biological data have the degree of agreement with the biological data transmitted from the client beyond a set value.

Description

technical field [0001] The present invention relates to a system, client and server for performing biometric authentication by comparing biometric data of a user with registered reference biometric data. Background technique [0002] Highly accurate personal authentication technology is becoming more and more important in IT (Information Technology) systems. Specifically, biometric authentication using biometric information for personal authentication has received more attention. Biometric authentication reads biometric information such as fingerprints, palm vein patterns, and iris using an input device, creates biometric data obtained by extracting features of the biometric information, and compares it with registered reference biometric data , to authenticate the user. Because it does not bring inconvenience to users to enter passwords and the burden of confidentiality management, it is not easy to generate illegal use, and has high security, so biometric authentication ...
