Abstract

A first computer and a second computer are each connected to a communication network. User data is generated for a user by the first computer based on receiving, from the second computer, initial enrollment biometric data for the user. The user is authorized by the first computer based on a confidence score for challenge biometric data exceeding a first confidence threshold. Then the user data is updated with updated enrollment biometric data by the first computer based on a confidence score for the updated enrollment biometric data exceeding a second confidence threshold. The second confidence threshold is greater than the first confidence threshold. The initial enrollment biometric data is deleted by the second computer after a predetermined time of receiving the initial enrollment biometric data.

First claim

The invention claimed is:

1. A system, comprising:
a communication network; and
a first computer and a second computer each connected to the communication network;
wherein the first computer is programmed to:
generate user data for a user based on receiving, from the second computer, initial enrollment biometric data for the user;
authenticate the user based on a confidence score for challenge biometric data exceeding a first confidence threshold;
then update the user data with updated enrollment biometric data based on a confidence score for the updated enrollment biometric data exceeding a second confidence threshold, wherein the second confidence threshold is greater than the first confidence threshold; and
perform a comparison of the confidence score for the updated enrollment biometric data to the second confidence threshold and prevent the user from operating controls for a structure based on determining from the comparison that the confidence score for the updated enrollment biometric data does not exceed the second confidence threshold.

2. The system of claim 1 , wherein the first computer is further programmed to, upon authenticating the user, permit the user to access a structure.

3. The system of claim 1 , wherein the first computer is further programmed to prevent the user from accessing a structure based on failing to authenticate the user within a second predetermined time of receiving the initial enrollment biometric data.

4. The system of claim 1 , wherein the first computer is further programmed to, upon determining to not authenticate the user, prevent the user from accessing a structure.

5. The system of claim 1 , wherein the first computer is further programmed to, upon updating the user data, permit the user to access a structure based on the updated user data.

6. The system of claim 1 , wherein the first computer is further programmed to update the user data based additionally on receiving a user input.

7. The system of claim 1 , wherein the first computer is further programmed to update the user data based additionally on authorizing a portable device associated with the user.

8. The system of claim 1 , wherein the first computer is further programmed to:
after updating the user data, obtain future challenge biometric data based on detecting the user; and
authorize the user based on a confidence score for the future challenge biometric data exceeding the second confidence threshold.

9. The system of claim 8 , wherein the first computer is further programmed to, upon authorizing the user, permit the user to at least one of access a structure and operate controls for the structure on the updated user data.

10. The system of claim 8 , wherein the first computer is further programmed to, upon determining to not authorize the user, prevent the user from accessing a structure.

11. The system of claim 8 , wherein the future challenge biometric data is obtained from at least one of exterior sensors positioned to face an environment around a structure and interior sensors positioned to face an area defined by the structure.

12. The system of claim 1 , wherein the challenge biometric data is obtained from exterior sensors positioned to face an environment around a structure, and the updated enrollment biometric data is obtained from the exterior sensors and interior sensors positioned to face an area defined by the structure.

13. The system of claim 1 , wherein the second computer is further programmed to delete the initial enrollment biometric data based on providing the initial enrollment biometric data to the first computer.

14. The system of claim 1 , wherein the second computer is further programmed to receive the initial enrollment biometric data from a third computer.

15. The system of claim 1 , wherein the second computer is programmed to delete the initial enrollment biometric data after a predetermined time of receiving the initial enrollment biometric data.

16. A method, comprising:
generating, at a first computer, user data for a user based on receiving, from a second computer, initial enrollment biometric data for the user;
authenticating the user based on a confidence score for challenge biometric data exceeding a first confidence threshold;
then updating the user data with updated enrollment biometric data based on a confidence score for the updated enrollment biometric data exceeding a second confidence threshold, wherein the second confidence threshold is greater than the first confidence threshold; and
performing a comparison of the confidence score for the updated enrollment biometric data to the second confidence threshold and preventing the user from operating controls for a structure based on determining from the comparison that the confidence score for the updated enrollment biometric data does not exceed the second confidence threshold.

17. The method of claim 16 , further comprising:
after updating the user data, obtaining, at the first computer, future challenge biometric data based on detecting the user; and
authorizing the user based on a confidence score for the future challenge biometric data exceeding the second confidence threshold.

18. The method of claim 17 , further comprising, upon authorizing the user, permitting, at the first computer, the user to at least one access a structure and to operate controls for the structure based on the updated user data.

19. The method of claim 16 , further comprising deleting, at the second computer, the initial enrollment biometric data based on providing the initial enrollment biometric data to the first computer.

20. The method of claim 16 , further comprising deleting, at the second computer, the initial enrollment biometric data after a predetermined time of receiving the initial enrollment biometric data.
