BIOMETRIC AUTHENTICATION SYSTEM
First Claim
1. A biometric authentication system, comprising:
- a client device that receives biometric information;
an authenticating server that receives the biometric information from the client device and performs personal authentication; and
a managing device that manages the personal authentication performed by the authenticating server, whereinthe authenticating server includesa registration-biometric-information storage unit that stores therein registration biometric information that is biometric information of registered users previously registered as users, and is referred to at the personal authentication as comparison targets to the received biometric information, and personal authenticating methods;
a biometric-information matching unit that matches the received biometric information with the registration biometric information stored in the registration-biometric-information storage unit;
a similarity-determination matching-biometric-information storage unit that stores therein the received biometric information as similarity-determination matching biometric information to be Matched for similarity determination, to determine based on the matching whether the received biometric information is similar biometric information similar to any of the registration biometric information stored in the registration-biometric-information storage unit;
a similar-biometric-information determining unit that determines whether the similar biometric information is included in the similarity-determination matching biometric information by comparing the similarity-determination matching biometric information stored in the similarity-determination matching-biometric-information storage unit and the registration biometric information stored in the registration-biometric-information storage unit with each other at a predetermined time; and
a similarity-information output unit that outputs similarity information related to the similarity-determination matching biometric information determined to be the similar biometric information when the similarity-determination matching biometric information determined by the similar-biometric-information determining unit to be the similar biometric information is included in the similarity-determination matching biometric information stored in the similarity-determination matching-biometric-information storage unit.

Abstract
Registration biometric information of registered users previously registered and personal authenticating methods are stored. The received biometric information and the registration biometric information is compared with each other. The received biometric information is stored as similarity-determination matching biometric information to be matched for similarity determination to determine based on the matching whether the received biometric information is similar biometric information similar to any of the registration biometric information, the similarity-determination matching biometric information and the registration biometric information is compared with each other at a predetermined time to determined whether the similar biometric information is included in the similarity-determination matching biometric information, and similarity information related to the similarity-determination matching biometric information determined to be the similar biometric information is outputted when the similarity-determination matching biometric information determined to be the similar biometric information is included in the similarity-determination matching biometric information.

20. A computer readable storage medium having stored therein a biometric authentication program for a biometric authentication system that includes a client device that receives biometric information, an authenticating server that receives the biometric information from the client device and performs personal authentication, and a managing device that manages the personal authentication performed by the authenticating server, the biometric authentication program causing a computer to execute a process comprising:
-
storing registration biometric information that is biometric information of registered users previously registered as users, and is referred to at the personal authentication as comparison targets to the received biometric information, and personal authenticating methods in a first storage unit; matching the received biometric information with the registration biometric information stored in the first storage unit; storing the received biometric information as similarity-determination matching biometric information to be matched for similarity determination in a second storage unit, to determine based on the matching whether the received biometric information is similar biometric information similar to any of the registration biometric information stored in the first storage unit; determining whether the similar biometric information is included in the similarity-determination matching biometric information by comparing the similarity-determination matching biometric information stored in the second storage unit and the registration biometric information stored in the first storage unit with each other at a predetermined time; and outputting similarity information related to the similarity-determination matching biometric information determined to be the similar biometric information when the similarity-determination matching biometric information determined to be the similar biometric information in the determining is included in the similarity-determination matching biometric information stored in the second storage unit.
