Abstract

Upon obtaining biometric data for a user of a structure while the user is outside the structure, user data for the user is updated based on a confidence score for the biometric data exceeding a first confidence threshold. Based on the confidence score for the biometric data not exceeding the first confidence threshold, instructions are provided to the user to provide updated biometric data. Then the user data is updated based on a confidence score for the updated biometric data exceeding a second confidence threshold. The second confidence threshold is greater than the first confidence threshold. Structure components are controlled based on the updated user data.

First claim

The invention claimed is:

1. A system, comprising a computer including a processor and a memory, the memory storing instructions executable by the processor to:
after receiving biometric data for a user, determine that user data for the user is unavailable, instruct the user to exit a structure, and generate user data for the user;
obtain secondary enrollment biometric data for the user of the structure while the user is outside of the structure;
based on determining that a confidence score for the secondary enrollment biometric data does not exceed a first confidence threshold, provide instructions to the user to provide updated secondary enrollment biometric data;
then, after receiving the updated secondary enrollment biometric data, generate updated user data based on a confidence score for the updated secondary enrollment biometric data exceeding a second confidence threshold, wherein the second confidence threshold is greater than the first confidence threshold;
authorize the user based on a confidence score for challenge biometric data exceeding the first confidence threshold;
allow the user to re-enter the structure based on authorizing the user and then verify the user inside the structure based upon a confidence score for secondary challenge biometric data obtained outside of the structure exceeding the second confidence threshold; and
control structure components based on verifying the user.

2. The system of claim 1 , wherein the instructions further include instructions to generate the user data based on obtaining enrollment biometric data for the user inside the structure before obtaining the secondary enrollment biometric data while the user is outside of the structure.

3. The system of claim 2 , wherein the instructions further include instructions to, upon detecting the user inside the structure, provide instructions, via the structure components, to the user to provide the enrollment biometric data.

4. The system of claim 1 , wherein the instructions further include instructions to, prior to obtaining the secondary enrollment biometric data, actuate the structure components based on determining a difference between a light parameter at an exterior sensor and a light parameter at an interior sensor, wherein the interior sensor is positioned inside the structure and the exterior sensor is positioned outside of the structure.

5. The system of claim 4 , wherein the structure component is at least one of a lighting component or a window.

6. The system of claim 1 , wherein the instructions further include instructions to, upon determining to not authorize the user, prevent the user from accessing the structure.

7. The system of claim 1 , wherein the instructions further include instructions to obtain the challenge biometric data based on one of receiving a user input or detecting an authorized portable device within a predetermined distance of the structure.

8. The system of claim 1 , wherein the instructions to control structure components include instructions to permit the user to operate controls for the structure.

9. The system of claim 1 , wherein the instructions further include instructions to, upon determining not to verify the user, prevent the user from operating controls for the structure.

10. The system of claim 1 , wherein the instructions further include instructions to update the user data based on receiving a user input.

11. The system of claim 1 , wherein the instructions further include instructions to update the user data based additionally on detecting an authorized portable device within a predetermined distance of the structure.

12. A method, comprising:
after receiving biometric data for a user, determining that user data for the user is unavailable, instructing the user to exit a structure, and generating user data for the user;
obtaining secondary enrollment biometric data for the user of the structure while the user is outside of the structure;
based on determining that a confidence score for the secondary enrollment biometric data does not exceed a first confidence threshold, providing instructions to the user to provide updated secondary enrollment biometric data;
then, after receiving the updated secondary enrollment biometric data, generating updated user data based on a confidence score for the updated secondary enrollment biometric data exceeding a second confidence threshold, wherein the second confidence threshold is greater than the first confidence threshold;
authorizing the user based on a confidence score for challenge biometric data exceeding the first confidence threshold;
allowing the user to re-enter the structure based on authorizing the user and then verifying the user inside the structure based upon a confidence score for secondary challenge biometric data obtained outside of the structure exceeding the second confidence threshold; and
controlling structure components based on verifying the user.

13. The method of claim 12 , further comprising, prior to obtaining the secondary enrollment biometric data, actuating the structure components based on determining a difference between light parameter at an exterior sensor and light parameter at an interior sensor, wherein the interior sensor is positioned inside the structure and the exterior sensor is positioned outside of the structure.

14. The method of claim 12 , wherein generating the user data is based on obtaining enrollment biometric data for the user inside the structure before obtaining the secondary enrollment biometric data while the user is outside of the structure.

15. The method of claim 12 , further comprising, prior to obtaining the secondary enrollment biometric data, actuating the structure components based on determining a difference between a light parameter at an exterior sensor and a light parameter at an interior sensor, wherein the interior sensor is positioned inside the structure and the exterior sensor is positioned outside of the structure.

16. The method of claim 12 , further comprising obtaining the challenge biometric data based on one of receiving a user input or detecting an authorized portable device within a predetermined distance of the structure.

17. The method of claim 12 , wherein controlling structure components includes permitting the user to operate controls for the structure.

18. The method of claim 12 , further comprising updating the user data based on receiving a user input.

19. The method of claim 12 , further comprising updating the user data based on detecting an authorized portable device within a predetermined distance of the structure.
