Abstract

Apparatus and methods of passive biometric enrollment are configured to provide an introductory experience upon activation of a computer device. The introductory experience involves a user performing movements that allow collection of passive user biometrics by a sensor of the device. The sensor may collect the passive user biometrics while the user performs the movements. The computer device may calibrate one or more features of the computer device based on the movements. The computer device may receive user credentials from the user. The computer device may store a biometric profile including the passive user biometrics in association with the user credentials.

Claims

1. A method of enrolling user biometrics for a device, comprising:

providing an introductory experience upon activation of the device, wherein the introductory experience involves a user performing movements that allow collection of passive user biometrics by a sensor of the device, wherein providing the introductory experience includes generating a virtual object with which the user interacts to advance the introductory experience;

collecting the passive user biometrics while the user performs the movements;

calibrating the device based on the movements;

receiving user credentials from the user, and

storing a biometric profile including the passive user biometrics in association with the user credentials.

3. The method of claim 1, wherein the virtual object is positioned relative to the sensor based on a missing biometric marker for a biometric profile.

4. The method of claim 1, wherein the virtual object is a hologram.

5. The method of claim 1, wherein collecting passive user biometrics comprises obtaining an image of an eye of the user.

6. The method of claim 1, wherein collecting user biometrics comprises obtaining an image of at least a portion of a face of the user.

7. The method of claim 1, further comprising:

determining that a collected passive biometric is deficient; and

adding or modifying an event of the introductory experience to allow capture of the collected passive biometric again.

2. (canceled)

8. A computer device for enrolling a user in passive biometric identification, comprising:

a processor,

a memory in communication with the processor,

wherein the processor is configured to;

provide an introductory experience upon activation of the device, wherein the introductory experience involves a user performing movements that allow collection of passive user biometrics by a sensor of the device, wherein the introductory experience includes a virtual object with which the user interacts to advance the introductory experience;

collect the passive user biometrics while the user performs the movements;

calibrate the device for the user based on the movements;

receive user credentials from the user, and

store a biometric profile including the passive user biometrics in association with the user credentials.

10. The computer device of claim 8, wherein the processor positions the virtual object relative to the sensor based on a missing biometric marker for a biometric profile.

11. The computer device of claim 8, wherein the virtual object is a hologram.

12. The computer device of claim 8, further comprising an image capture device configured to obtain an image of an eye of the user.

13. The computer device of claim 8, further comprising an image capture device configured to obtain an image of at least a portion of a face of the user.

14. The computer device of claim 8, wherein the processor is configured to:

determine that a collected passive biometric is deficient; and

add or modify an event of the introductory experience to allow capture of the collected passive biometric again.

9. (canceled)

15. A non-transitory computer-readable medium storing instructions executable by a processor for enrolling a user in passive biometric identification, comprising instructions to:

provide an introductory experience upon activation of the device, wherein the introductory experience involves a user performing movements that allow collection of passive user biometrics by a sensor of the device;

generate a virtual object with which the user interacts to advance the introductory experience;

collect the passive user biometrics while the user performs the movements;

calibrate the device for the user based on the movements;

receive user credentials from the user; and

store a biometric profile including the passive user biometrics in association with the user credentials.

17. The non-transitory computer-readable medium of claim 15, further comprising instructions to position the virtual object relative to the sensor based on a missing biometric marker for a biometric profile.

18. The non-transitory computer-readable medium of claim 15, wherein the virtual object is a hologram.

19. The non-transitory computer-readable medium of claim 15, further comprising instructions to control an image capture device to obtain an image of an eye of the user or at least a portion of a face of the user.

20. The non-transitory computer-readable medium of claim 15, further comprising instructions to:

determine that a collected passive biometric is deficient; and

add or modify an event of the introductory experience to allow capture of the collected passive biometric again.
