Abstract

A template of a biometric attribute for use with a biometric recognition device includes a long term component and a short term component. The long term component can include a plurality of nodes that each represents at least a portion of the biometric attribute. The short term component may include one or more newly captured nodes that each represents at least a portion of the biometric attribute.

Claims

1. A template of a biometric attribute for use in a biometric recognition device, comprising:

a long term component comprising a plurality of nodes that each represent at least a portion of the biometric attribute, the long term component being updated based on node information associated with each node; and

a short term component comprising one or more recently captured nodes that each represents at least a portion of the biometric attribute.

2. The template as in claim 1, wherein the node information comprises information regarding at least one of coverage area, matchability, and an age of each node.

3. The template as in claim 1, wherein the biometric template comprises a fingerprint template.

4. An electronic device, comprising:

a biometric recognition device for capturing nodes that each represent at least a portion of a biometric attribute; and

a memory operatively connected to the biometric recognition device for storing one or more templates associated with the biometric attribute, at least one template including a long term component comprising a plurality of nodes and a short term component comprising one or more recently captured nodes.

5. The electronic device as in claim 4, further comprising a processing device operatively connected to the biometric recognition device and to the memory, the processing device adapted to determine whether a newly captured node matches at least one node in at least one of the short term component and the long term component.

6. The electronic device as in claim 5, wherein the processing device comprises a secure processing device.

7. The electronic device as in claim 4, wherein the biometric recognition device comprises a fingerprint recognition device and the biometric attribute comprises at least a portion of a fingerprint.

8. The electronic device as in claim 4, wherein the memory comprises a secure memory.

9. The electronic device as in claim 4, wherein the electronic device is a smart telephone.

10. A method for updating a fingerprint template, comprising:

determining if a newly captured node matches at least one node in at least one of a short term component and a long term component of the fingerprint template, wherein the long term component comprises a plurality of nodes and a short term component comprises one or more recently captured nodes;

if the newly captured node matches at least one node in at least one of the short term component and the long term component of the fingerprint template, storing the newly captured node in the short term component;

removing a recently captured node from the short term component; and

determining whether the removed recently captured node is to be included in the long term component of the fingerprint template.

11. The method as in claim 10, further comprising receiving a newly captured node.

12. The method as in claim 10, further comprising determining whether the newly captured node is to be stored in the short term component prior to storing the newly captured node in the short term component.

13. The method as in claim 12, further comprising determining node information for the newly captured node prior to determining whether the newly captured node is to be stored in the short term component.

14. The method as in claim 13, wherein the determination as to whether the newly captured node is to be stored in the short term component is based on the node information associated with the newly captured node.

15. The method as in claim 12, further comprising storing the removed recently captured node in the long term component.

16. The method as in claim 12, wherein the determination as to whether the removed recently captured node is to be included in the long term component is based on a coverage area of the recently captured node.

17. A method for updating a biometric template, comprising:

determining if a newly captured node that represents at least a portion of a biometric attribute matches at least one node in at least one of a short term component and a long term component of the biometric template, wherein the long term component comprises a plurality of nodes and a short term component comprises one or more recently captured nodes; and

if the newly captured node matches at least one node in at least one of the short term component and the long term component, storing the newly captured node in at least one of the short term component and the long term component, wherein the newly captured node is stored in the short term component based on node information associated with the newly captured node and the newly captured node is stored in the long term component based on a coverage area of the newly captured node.

18. The method as in claim 17, wherein the node information associated with the newly captured node comprises at least one of coverage area, matchability, and age of the newly captured node.

19. The method as in claim 17, further comprising removing a recently captured node from the short term component.

20. The method as in claim 19, wherein a recently captured node is removed from the short term component based on the node information associated with the node.
