METHOD OF CONTROLLING BIOMETRIC AUTHENTICATION SYSTEM, NON-TRANSITORY, COMPUTER READABLE STORAGE MEDIUM AND BIOMETRIC AUTHENTICATION SYSTEM
First Claim
1. A control method for 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 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 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 table;
calculating, at the server, an authentication success rate of the user from the acquired previous authentication result;
transmitting the reference biometric data from the server to the client when the authentication success rate is less than or equal to a certain value and then calculating, at the client, a degree of matching between the biometric authentication data and the reference biometric data transmitted from the server; and
determining, based on the degree of matching, 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 for 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, according to a process comprising:
-
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 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 table; calculating, at the server, an authentication success rate of the user from the acquired previous authentication result; transmitting the reference biometric data from the server to the client when the authentication success rate is less than or equal to a certain value; calculating, at the client, a degree of matching between the biometric authentication data and the reference biometric data transmitted from the server; and determining, based on the degree of matching, whether or not the authentication of the user has succeeded.

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 for storing a table in which identification information identifying user and a previous authentication result of the user are associated with each other, a calculating unit for referring to the identification information and the table and calculating an authentication success rate of the user from a previous authentication result of the user corresponding to the identification information, and a transmitting unit for transmitting the reference biometric data to the client when the authentication success rate is less than or equal to a certain value, the client including a determining unit for calculating a degree of matching between the biometric authentication data and the reference biometric data, which is transmitted from the server, and determining, based on the degree of matching, whether or not the authentication of the user has succeeded.
