Authentication via accelerometer
View Patent ↗Authentication via accelerometer may be provided. Upon receiving a request to unlock a device, a user may perform an authentication movement that may be detected by an accelerometer on the device. If the authentication movement is determined to match an approved movement, the device may be unlocked.
1. A method for authenticating a user, comprising:
capturing, using at least one sensor of a device:
an authentication movement comprising a plurality of characteristics describing a movement of the device, and
at least one image comprising the user and a field of view of the device;
determining whether the authentication movement comprises an approved movement and whether the at least one image comprises a facial recognition of the user;
determining whether the authentication movement is correlated with the at least one image, wherein determining whether the authentication movement is correlated with the at least one image comprises determining whether a position of the user within the field of view of the device is expected based at least in part on the plurality of characteristics describing the movement of the device; and,
if the authentication movement comprises an approved movement, the at least one image comprises a verified facial recognition, and the approved movement is correlated with the at least one image, authenticating the user.
2. The method of claim 1 , wherein the approved movement comprises a time-dependent movement.
3. The method of claim 1 , wherein the approved movement comprises a location-dependent movement.
4. The method of claim 3 , wherein the location-dependent movement comprises a directional component.
5. The method of claim 4 , further comprising detecting the directional component via a compass associated with the device.
6. The method of claim 1 , wherein determining whether the at least one image comprises a facial recognition of the user comprises determining whether the at least one image comprises a plurality of location points on a face of the user.
7. The method of claim 1 , wherein determining whether the authentication movement matches the approved movement comprises:
detecting a second authentication movement associated with a second device; and
determining whether the authentication movement corresponds with the second authentication movement.
8. The method of claim 7 , wherein the second device comprises a motion capture device.
9. The method of claim 7 , wherein the second device comprises a second at least one sensor.
10. The method of claim 1 , wherein the authentication movement matches the approved movement if a variance between the authentication movement and the approved movement is less than a permitted variance.
11. A system for authenticating a user, comprising:
an accelerometer;
a camera;
a memory store; and
a processor coupled to the memory store, wherein the processor is configured to:
capture at least one image using the camera, the at least one image comprising the user and a field of view of the system;
detect an authentication movement using the accelerometer;
determining whether the authentication movement comprises an approved movement and whether the at least one image comprises a facial recognition of the user;
determine whether the authentication movement is correlated with the at least one image, wherein determining whether the authentication movement is correlated with the at least one image comprises determining whether a position of the user within the field of view of the device is expected based at least in part on the plurality of characteristics describing the movement of the device; and,
if the authentication movement comprises an approved movement, the at least one image comprises a verified facial recognition, and the approved movement is correlated with the at least one image, authenticating the user.
12. The system of claim 11 , wherein the processor being configured to authenticate the user comprises being configured to unlock the apparatus.
13. The system of claim 11 , wherein the processor being configured to determine whether the authentication movement is correlated with the at least one image comprises being configured to receive a second authentication movement from at least one second sensor.
14. The system of claim 13 , wherein the at least one second sensor comprises a remote sensor.
15. The system of claim 11 , wherein the processor is further configured to:
if the authentication movement does not comprise an approved movement, the at least one image does not comprise a verified facial recognition, or the approved movement is not correlated with the at least one image, capture biometric information describing the user.
16. A non-transitory computer readable medium comprising program code that, when executed, causes a method to be performed, the method comprising:
capturing, using at least one sensor of a device:
an authentication movement comprising a plurality of characteristics describing a movement of the device, and
at least one image comprising the user and a field of view of the device;
determining whether the authentication movement comprises an approved movement and whether the at least one image comprises a facial recognition of the user;
determining whether the authentication movement is correlated with the at least one image, wherein determining whether the authentication movement is correlated with the at least one image comprises determining whether a position of the user within the field of view of the device is expected based at least in part on the plurality of characteristics describing the movement of the device; and,
if the authentication movement comprises an approved movement, the at least one image comprises a verified facial recognition, and the approved movement is correlated with the at least one image, authenticating the user.
17. The non-transitory computer readable medium of claim 16 , wherein determining that the at least one image comprises a facial recognition of the user comprises correlating the authentication movement with a three-dimensional analysis of the user of the device.
18. The non-transitory computer readable medium of claim 16 , wherein determining that the at least one image comprises a facial recognition of the user comprises correlating a video capture by the device to an inverse of the authentication movement.
19. The non-transitory computer readable medium of claim 16 , wherein the method further comprises, in response to determining that the authentication movement does not match the approved movement, capturing an image of a user of the device.
20. The non-transitory computer readable medium of claim 16 , wherein the method further comprises:
capturing, using the at least one sensor of the device, at least one additional authentication criterion comprising at least one of a password, a passcode, a finger-swipe pattern, or biometric data;
determining whether the at least one additional authentication criterion comprises an approved authentication criterion comprising a user-defined criterion; and,
if the additional authentication criterion comprises an approved authentication criterion, authenticating the user.
