Method of controlling biometric authentication system, non-transitory, computer readable storage medium and biometric authentication system
First Claim
1. A control method of controlling a biometric authentication system including a server that stores reference biometric data used as a reference for authentication of a user, and a client that acquires biometric authentication data from the user, the control method comprising:
- saving, in the server, associated information in which identification information identifying the user and a previous authentication result of the user are associated with each other;
transmitting the identification information identifying the user to the server from the client;
referring to, at the server, the identification information transmitted from the client and acquiring a previous authentication result of the user corresponding to the identification information from the saved associated information;
calculating, at the server, an authentication success rate of the user from the acquired previous authentication result;
determining, at the server, to calculate a degree of matching at the client when the calculated authentication success rate does not satisfy a threshold, and to calculate the degree of matching at the server when the calculated authentication success rate satisfies the threshold;
transmitting, when said determining determines to calculate the degree of matching at the client, the reference biometric data from the server to the client and then calculating, at the client, the degree of matching between the biometric authentication data and the reference biometric data transmitted from the server, so that the degree of matching is thereby calculated at the client when the authentication success rate does not satisfy the threshold; and
determining, based on the degree of matching calculated at the client, whether or not the authentication of the user has succeeded.

Abstract
A control method for controlling a biometric authentication system including a server that stores reference biometric data, and a client that acquires biometric authentication data of the user, has saving in the server a table in which identification information identifying the user and a previous authentication result of the user are associated with each other, transmitting the identification information to the server, referring to the identification information and acquiring a previous authentication result of the user corresponding to the identification information from the table, calculating, an authentication success rate of the user from the acquired previous authentication result, transmitting the reference biometric data to the client when the authentication success rate is less than or equal to a certain value, calculating, a degree of matching between the biometric authentication data and the reference biometric data, and determining, whether or not the authentication of the user has succeeded.

6. A non-transitory, computer readable storage medium storing a program to control a biometric authentication system including a server that stores reference biometric data used as a reference for authentication of a user, and a client that acquires biometric authentication data from the user, the program, when executed, causes the biometric authentication system to perform a process comprising:
-
saving, in the server, associated information in which identification information identifying the user and a previous authentication result of the user are associated with each other; transmitting the identification information identifying the user to the server from the client; referring to, at the server, the identification information transmitted from the client and acquiring a previous authentication result of the user corresponding to the identification information from the stored associated information; calculating, at the server, an authentication success rate of the user from the acquired previous authentication result; determining to calculate a degree of matching at the client when the calculated authentication success rate does not satisfy a threshold, and to calculate the degree of matching at the server when the calculated authentication success rate satisfies the threshold; when said determining determines to calculate the degree of matching at the client, transmitting the reference biometric data from the server to the client, and calculating, at the client, the degree of matching between the biometric authentication data and the reference biometric data transmitted from the server, so that the degree of matching is thereby calculated at the client when the authentication success rate does not satisfy the threshold; and determining, based on the degree of matching calculated at the client, whether or not the authentication of the user has succeeded. - View Dependent Claims (12)

7. A biometric authentication system comprising:
-
a server that stores reference biometric data used as a reference for authentication of a user; and a client that acquires biometric authentication data from the user, the server including a storage unit to store associated information in which identification information identifying user and a previous authentication result of the user are associated with each other, a calculating unit to refer to the identification information and the stored associated information, to calculate an authentication success rate of the user from a previous authentication result of the user corresponding to the identification information, and to determine to calculate a degree of matching at the client when the calculated authentication success rate does not satisfy a threshold and to calculate the degree of matching at the server when the calculated authentication success rate satisfies the threshold, and a transmitting unit to transmit the reference biometric data to the client when the calculating unit determines to calculate the degree of matching at the client, the client including a determining unit to, when the calculating unit of the server determines to calculate the degree of matching at the client, calculate the degree of matching between the biometric authentication data and the reference biometric data, which is transmitted from the server to the client, and to determine, based on the degree of matching, whether or not the authentication of the user has succeeded, so that the degree of matching is thereby calculated at the client when the authentication success rate does not satisfy the threshold. - View Dependent Claims (8, 9, 10, 13)
