Abstract

Claims (45)

1. A non-transitory computer readable medium comprising executable code, that when executed by one or more processors, causes the one or more processors to:

receive, at a reader device from a memory of a portable credential device of a user, at least one of a first image of the user or a first representation of a face of the user;

if a first image of the user was received, then generate, at the reader device, a generated representation of the face of the user using the first image;

capture, at the reader device, a second image of the user and generate a second representation of the face of the user using the second image;

receive, at the reader device from the user, an authentication factor;

determine validity of the authentication factor;

determine, subsequent to determining the validity of the authentication factor, a confidence of a match between the second representation and at least one of the first representation and the generated representation; and

if the confidence is below a minimum threshold indicating an insufficient match and the authentication factor is determined to be valid, at least one of supplement or replace at least one of the first image or first representation with the second image or second representation, respectively.

2. The non-transitory computer readable medium of claim 1 , wherein the executable code, when executed by the one or more processors, further causes the one or more processors to permit access by the user to a secure asset.

3. The non-transitory computer readable medium of claim 1 , wherein at least one of supplementing or replacing at least one of the first image or first representation with the second image or second representation, respectively, comprises sending at least one of the second image or second representation to the portable credential device for storing at the memory of the portable credential device.

4. The non-transitory computer readable medium of claim 2 , wherein whether the confidence is below the minimum threshold is based on confidence values of prior attempts by the user to access the secure asset.

5. The non-transitory computer readable medium of claim 4 , wherein it is determined that the confidence is below the minimum threshold in instances where the confidence values of prior attempts by the user to access the secure asset are trending downward.

6. The non-transitory computer readable medium of claim 1 , wherein the authentication factor is a credential from the memory of the portable credential device of the user.

7. The non-transitory computer readable medium of claim 1 , wherein the authentication factor is a biometric of the user.

8. The non-transitory computer readable medium of claim 1 , wherein the authentication factor is a password known to the user.

9. The non-transitory computer readable medium of claim 1 , wherein:

receiving the authentication factor comprises receiving a plurality of authentication factors;

determining validity of the authentication factor comprises determining validity of each of the plurality of authentication factors; and

at least one of supplementing or replacing at least one of the first image or first representation with the second image or second representation, respectively, if the confidence is below the minimum threshold and the authentication factor is determined to be valid comprises at least one of supplementing or replacing at least one of the first image or first representation with the second image or second representation, respectively, if the confidence is below the minimum threshold and at least one of the plurality of authentication factors is determined to be valid.

10. A device for permitting access to a secure asset, the device comprising:

at least one processor; and

memory storing instructions that when executed by the at least one processor cause the at least one processor to:

receive, at a reader device from a memory of a portable credential device of a user, at least one of a first image of the user or a first representation of a face of the user;

if a first image of the user was received, then generate, at the reader device, a generated representation of the face of the user using the first image;

capture, at the reader device, a second image of the user and generate a second representation of the face of the user using the second image;

receive, at the reader device from the user, an authentication factor;

determine validity of the authentication factor;

determine, subsequent to determining the validity of the authentication factor, a confidence of a match between the second representation and at least one of the first representation and the generated representation; and

if the confidence is below a minimum threshold indicating an insufficient match and the authentication factor is determined to be valid, at least one of supplement or replace at least one of the first image or first representation with the second image or second representation, respectively.

11. The device of claim 10 , wherein the instructions, when executed by the at least one processor, further causes the at least one processor to permit access by the user to a secure asset.

12. The device of claim 10 , wherein at least one of supplementing or replacing at least one of the first image or first representation with the second image or second representation, respectively, comprises sending at least one of the second image or second representation to the portable credential device for storing at the memory of the portable credential device.

13. The device of claim 10 , wherein whether the confidence is below the minimum threshold is based on confidence values of prior attempts by the user to access the secure asset.

14. The device of claim 13 , wherein it is determined that the confidence is below the minimum threshold in instances where the confidence values of prior attempts by the user to access the secure asset are trending downward.

15. The device of claim 10 , wherein the authentication factor is a credential from the portable credential device of the user.

16. The device of claim 10 , wherein the authentication factor is a biometric of the user.

17. The device of claim 10 , wherein the authentication factor is a password known to the user.

18. The device of claim 10 , wherein:

receiving the authentication factor comprises receiving a plurality of authentication factors;

determining validity of the authentication factor comprises determining validity of each of the plurality of authentication factors; and

at least one of supplementing or replacing at least one of the first image or first representation with the second image or second representation, respectively, if the confidence is below the minimum threshold and the authentication factor is determined to be valid comprises at least one of supplementing or replacing at least one of the first image or first representation with the second image or second representation, respectively, if the confidence is below the minimum threshold and at least one of the plurality of authentication factors is determined to be valid.

19. The device of claim 10 , wherein the device comprises a reader device connected with a facial recognition module that is external to the reader device, the facial recognition module comprising an optical sensor for capturing the second image of the user.

20. The device of claim 10 , wherein:

the device comprises a reader device connected with a facial recognition module that is external to the reader device;

the reader device is configured with the instructions that cause the at least one processor to receive the authentication factor and determine validity of the authentication factor; and

the facial recognition module comprises an optical sensor and is configured with the instructions for capturing the second image of the user.
