Abstract

Disclosed is a biometric authentication apparatus including: a biometric reading unit reading biometric data; a verification data storage unit storing a plurality of pieces of verification data for verifying against the biometric data; a priority order table storage unit storing a priority order table in which a priority order of searching the plurality of pieces of verification data is set; a control unit registering the priority order into the priority order table, and sequentially searching the verification data at an order based on the priority order registered in the priority order table when the biometric data is read by the biometric reading unit to verify the biometric data against the verification data; and an information unit informing of a verification result by the control unit.

Claims

1. A biometric authentication apparatus comprising:

a biometric reading unit reading biometric data;

a verification data storage unit storing a plurality of pieces of verification data for verifying against the biometric data;

a priority order table storage unit storing a priority order table in which a priority order of searching the plurality of pieces of verification data is set;

a control unit registering the priority order into the priority order table, and sequentially searching the verification data at an order based on the priority order registered in the priority order table when the biometric data is read by the biometric reading unit to verify the biometric data against the verification data; and

an information unit informing of a verification result by the control unit.

2. The biometric authentication apparatus of claim 1, wherein the biometric reading unit reads as the biometric data at least one of a fingerprint, a vein, an iris, a retina, a hand shape, a facial configuration, a somatotype and a voiceprint of the user.

3. A biometric authentication apparatus comprising:

a biometric reading unit reading biometric data;

a verification data storage unit storing a plurality of pieces of verification data for verifying against the biometric data;

a priority order table storage unit storing a priority order table in which a priority order of searching the plurality of pieces of verification data is set;

a control unit sequentially searching the verification data in an order based on the priority order when the biometric data is read by the biometric reading unit to verify the biometric data against the read verification data, the control unit changing the priority order of verification data which agrees with the biometric data as a verification result, to a higher rank and changing priority orders of other pieces of verification data to orders according to the change of the priority order of the agreed verification data to update the priority order table; and

an information unit informing of the verification result by the control unit.

4. The biometric authentication apparatus of claim 3, wherein the biometric reading unit reads as the biometric data at least one of a fingerprint, a vein, an iris, a retina, a hand shape, a facial configuration, a somatotype and a voiceprint of the user.

5. A biometric authentication method comprising:

a biometric reading step reading biometric data;

a verification data storage step storing a plurality of pieces of verification data for verifying against the biometric data;

a priority order table storage step storing a priority order table in which a priority order of searching the plurality of pieces of verification data is set;

a control step registering the priority order into the priority order table, and sequentially searching the verification data at an order based on the priority order registered in the priority order table when the biometric data is read at the biometric reading step to verify the biometric data against the verification data; and

an information step informing of a verification result by the control unit.

6. The biometric authentication method of claim 5, wherein the biometric reading step reads as the biometric data at least one of a fingerprint, a vein, an iris, a retina, a hand shape, a facial configuration, a somatotype and a voiceprint of the user.

7. A biometric authentication method comprising:

a biometric reading step reading biometric data;

a verification data storage step storing a plurality of pieces of verification data for verifying against the biometric data;

a priority order table storage step storing a priority order table in which a priority order of searching the plurality of pieces of verification data is set;

a control step sequentially searching the verification data in an order based on the priority order when the biometric data is read at the biometric reading step to verify the biometric data against the read verification data, the control step changing the priority order of verification data which agrees with the biometric data as a verification result, to a higher rank and changing priority orders of other pieces of verification data to orders according to the change of the priority order of the agreed verification data to update the priority order table; and

an information step informing of the verification result at the control step.

8. The biometric authentication method of claim 7, wherein the biometric reading step reads as the biometric data at least one of a fingerprint, a vein, an iris, a retina, a hand shape, a facial configuration, a somatotype and a voiceprint of the user.
