Abstract

A load balancing apparatus distributes a biometrics authentication request output from a client device to one of authenticating devices. The load balancing apparatus includes a storage unit that stores therein information on load evaluation indicative of load arising from particular processing in the biometric authentication; and a destination deciding unit that decides a destination of the biometrics authentication request based on the information on load evaluation present in the storage unit, a performance property of each authenticating device and a load thereon that changes depending on a processing situation.

Claims

1. A load balancing apparatus that distributes a biometrics authentication request output from a client device to one of authenticating devices that perform biometrics authentication in accordance with performance property of each authenticating device and a load thereon that changes depending on a processing situation, the load balancing apparatus comprising:

a storage unit that stores therein information on load evaluation indicative of load arising from particular processing in the biometric authentication; and

a destination deciding unit that decides a destination of the biometrics authentication request based on the information on load evaluation present in the storage unit, the performance property, and the load.

2. The load balancing apparatus according to claim 1, wherein the information on load evaluation includes a matching level threshold used for determining pass or failure of the biometrics authentication.

3. The load balancing apparatus according to claim 1, wherein the information on load evaluation includes a quality of matching data received from the client device along with the biometrics authentication request.

4. The load balancing apparatus according to claim 1, wherein the information on load evaluation includes a size of matching data received from the client device along with the biometrics authentication request.

5. The load balancing apparatus according to claim 1, wherein the information on load evaluation includes a matching algorithm for matching data received from the client device along with the biometrics authentication request.

6. The load balancing apparatus according to claim 1, wherein the information on load evaluation includes an authenticating mode for the biometrics authentication.

7. The load balancing apparatus according to claim 1, wherein the information on load evaluation includes a biometric-information type and a biometric information attribution of matching data received from the client device along with the biometrics authentication request.

8. The load balancing apparatus according to claim 2, further comprising a setting unit that sets a common matching level threshold in order to maintain compatibility between different application programs, if a matching level threshold of the client device and a matching level threshold of the authenticating device are different because different application programs are installed on the client device and the authenticating device, wherein

the information on load evaluation includes the common matching level threshold.

9. The load balancing apparatus according to claim 1, wherein, when receiving a storing request for reference data that is used for authenticating matching data received from the client device along with the biometrics authentication request,

the information on load evaluation includes a quality of the reference data, and

the destination deciding unit decides a destination of the storing request based on the information on load evaluation, the performance property, and the load.

10. The load balancing apparatus according to claim 9, wherein the information on load evaluation includes a threshold of the quality of the reference data.

11. A method of balancing load by distributing a biometrics authentication request output from a client device to one of authenticating devices that perform biometrics authentication in accordance with performance property of each authenticating device and a load thereon that changes depending on a processing situation, the method comprising:

storing information on load evaluation indicative of load arising from particular processing in the biometric authentication in a storage unit; and

deciding a destination of the biometrics authentication request based on the information on load evaluation present in the storage unit, the performance property, and the load.

12. The method according to claim 11, wherein the information on load evaluation includes a matching level threshold used for determining pass or failure of the biometrics authentication.

13. The method according to claim 11, wherein the information on load evaluation includes a quality of matching data received from the client device along with the biometrics authentication request.

14. The method according to claim 11, wherein the information on load evaluation includes a size of matching data received from the client device along with the biometrics authentication request.

15. The method according to claim 11, wherein the information on load evaluation includes a matching algorithm for matching data received from the client device along with the biometrics authentication request.

16. The method according to claim 11, wherein the information on load evaluation includes an authenticating mode for the biometrics authentication.

17. The method according to claim 11, wherein the information on load evaluation includes a biometric-information type and a biometric information attribution of matching data received from the client device along with the biometrics authentication request.

18. The method according to claim 12, further comprising setting a common matching level threshold in order to maintain compatibility between different application programs, if a matching level threshold of the client device and a matching level threshold of the authenticating device are different because different application programs are installed on the client device and the authenticating device, wherein

the information on load evaluation includes the common matching level threshold.

19. The method according to claim 11, wherein, when receiving a storing request for reference data that is used for authenticating matching data received from the client device along with the biometrics authentication request,

the information on load evaluation includes a quality of the reference data, and

deciding includes deciding a destination of the storing request based on the information on load evaluation, the performance property, and the load.

20. The method according to claim 19, wherein the information on load evaluation includes a threshold of the quality of the reference data.
