Abstract

An electronic device can include a processing device operatively connected to a biometric sensing device. The biometric sensing device may capture a biometric image each time a user interacts with the electronic device. When the user enters user identification data (UID) and a biometric image was recently captured, the biometric image is tagged with the UID. The user can access the electronic device and/or an application being accessed on the electronic device when a subsequently captured biometric image matches a tagged biometric image or an untagged biometric image that is assigned to a cluster that includes a tagged biometric image.

Claims

1. A method for authenticating a user of an electronic device that includes a biometric sensing device, the method comprising:

capturing, as part of background operations of the electronic device, a first biometric as the user interacts with the electronic device;

receiving user identification data (UID) from the user as the user interacts with the electronic device;

if the first biometric and the UID are received within a given time period of each other;

tagging the first biometric with the UID; and

assigning the tagged first biometric to a cluster, wherein the cluster comprises one or more biometrics associated with a respective biometric attribute of the user;

capturing a second biometric as the user interacts with the electronic device;

determining if the second biometric matches at least one biometric in the cluster; and

providing the user with access to the electronic device or to an application on the electronic device in response to determining that the second biometric matches at least one biometric in the cluster.

2. The method of claim 1, wherein:

the method further comprises, if the first biometric and the UID are not received within the given time period of each other, assigning the first biometric to the cluster; and

providing the user with access to the electronic device or to the application on the electronic device occurs in response to determining that the second biometric matches at least one biometric in the cluster that is tagged with the UID.

3. The method of claim 1, further comprising:

assigning the second biometric to the cluster when the second biometric matches the first biometric;

capturing a third biometric as the user interacts with the electronic device;

determining if the third biometric matches at least one biometric in the cluster; and

providing the user with access to the electronic device or to the application on the electronic device in response to determining that the third biometric matches at least one biometric in the cluster.

4. The method of claim 1, wherein the first and second biometrics each comprise facial recognition data.

5. The method of claim 4, wherein capturing the first biometric comprises using an optical sensor.

6. The method of claim 5, wherein capturing the first biometric further comprises capturing an image.

7. The method of claim 1, wherein capturing the first biometric comprises sensing light.

8. The method as in claim 1, further comprising:

prior to assigning the tagged first biometric to the cluster, determining if a maximum number of biometrics have been assigned to the cluster; and

if the maximum number of biometrics have been assigned to the cluster;

selecting one or more biometrics to be deleted; and

deleting at least one biometric from the cluster.

9. The method of claim 1, further comprising:

repeatedly capturing, as part of the background operations of the electronic device, biometrics as the user interacts with the electronic device; and

for each biometric of the repeatedly captured biometrics;

if a respective UID is received within the given time period of the biometric, tagging the biometric with the respective UID;

if the biometric matches at least one biometric in the cluster, storing the biometric in the cluster; and

if the biometric does not match at least one biometric in the cluster, storing the biometric in at least one different cluster.

10. An electronic device, comprising:

a biometric sensing device configured to capture, as part of background operations of the electronic device, biometrics as a user interacts with the electronic device;

a processing device operatively connected to the biometric sensing device and configured to;

receive user identification data (UID) from the user as the user interacts with the electronic device; and

if a biometric of the captured biometrics and the UID are received within a given time period of each other, tag the biometric with the UID; and

a memory operatively connected to the processing device and to the biometric sensing device, the memory configured to store the tagged biometric in a cluster, the cluster comprising one or more biometrics associated with a respective biometric attribute of the user.

11. The electronic device of claim 10, wherein the captured biometrics comprise facial recognition data.

12. The electronic device of claim 10, wherein:

the biometric is a first biometric; and

the processing device is further configured to;

determine if a second biometric of the captured biometrics matches at least one biometric in the cluster; and

provide the user with access to the electronic device or to an application on the electronic device in response to determining that the second biometric matches at least one biometric in the cluster.

13. The electronic device of claim 12, wherein:

the first biometric is captured at a first time, and

the second biometric is captured at a second time.

14. The electronic device of claim 10, wherein the biometric sensing device comprises an optical sensor.

15. The electronic device of claim 14, wherein the captured biometrics comprise facial recognition data.

16. The electronic device of claim 14, further comprising a display operatively connected to the processing device, wherein the optical sensor is included in at least a portion of the display.

17. A method for authenticating multiple users of an electronic device that includes a biometric sensing device, the method comprising:

capturing, as part of background operations of the electronic device, a first biometric as a first user interacts with the electronic device;

receiving first user identification data (UID) from the first user as the first user interacts with the electronic device;

if the first biometric and the first UID are received within a first given time period of each other;

tagging the first biometric with the first UID; and

assigning the tagged first biometric to a first cluster, wherein the first cluster comprises one or more biometrics associated with a respective biometric attribute of the first user;

capturing, as part of the background operations of the electronic device, a second biometric as a second user interacts with the electronic device;

receiving a second UID from the second user as the second user interacts with the electronic device; and

if the second biometric and the second UID are received within a second given time period of each other;

tagging the second biometric with the second UID; and

assigning the tagged second biometric to a second cluster, wherein the second cluster comprises one or more biometrics associated with a respective biometric attribute of the second user.

18. The method of claim 17, further comprising:

capturing a third biometric;

determining if the third biometric matches at least one biometric in the first or second clusters; and

providing access to the electronic device or to an application on the electronic device in response to determining that the third biometric matches at least one biometric in the first or second clusters.

19. The method of claim 18, further comprising:

if the third biometric matches at least one biometric in the first cluster, assigning the third biometric to the first cluster; and

if the third biometric matches at least one biometric in the second cluster, assigning the third biometric to the second cluster.

20. The method of claim 17, further comprising:

capturing, as part of the background operations of the electronic device, a third biometric as the first user interacts with the electronic device;

receiving a third UID from the first user as the first user interacts with the electronic device; and
