Facial recognition
First Claim
1. A method comprising:
- receiving, by a computing device, a first image and a second image;
detecting, by the computing device, a facial gesture at least in part by determining whether a difference between the first image and the second image indicates a facial gesture;
selecting, based at least in part on the detected facial gesture, the first image and the second image from among a plurality of images that includes at least the first image, the second image, and a third image;
subsequent to selecting the first image and the second image, determining, by the computing device, whether the first image and the second image are associated with a consistent identity, based at least in part on a similarity between the first image and the second image; and
determining, based at least in part on detecting the facial gesture and on determining whether the first image and the second image are associated with the consistent identity, whether to deny authentication with respect to accessing one or more functionalities controlled by the computing device.

Abstract
An example method includes receiving a first image and a second image of a face of a user, where one or both images have been granted a match by facial recognition. The method further includes detecting a liveness gesture based on at least one of a yaw angle of the second image relative to the first image and a pitch angle of the second image relative to the first image, where the yaw angle corresponds to a transition along a horizontal axis, and where the pitch angle corresponds to a transition along a vertical axis. The method further includes generating a liveness score based on a yaw angle magnitude and/or a pitch angle magnitude, comparing the liveness score to a threshold value, and determining, based on the comparison, whether to deny authentication to the user with respect to accessing one or more functionalities controlled by the computing device.

17. A device comprising:
-
a memory; and one or more processors operable to; receive a first image and a second image; detect a facial gesture at least in part by determining whether a difference between the first image and the second image indicates a facial gesture; select, based at least in part on the detected facial gesture, the first image and the second image from among a plurality of images that includes at least the first image, the second image, and a third image; subsequent to selecting the first image and the second image, determine whether the first image and the second image are associated with a consistent identity, based at least in part on a similarity between the first image and the second image; and determine, based at least in part on detecting the facial gesture and on determining whether the first image and the second image are associated with the consistent identity, whether to deny authentication with respect to accessing one or more functionalities controlled by the computing device. - View Dependent Claims (18, 19)

20. A computer-readable storage device encoded with instructions that, when executed, cause one or more programmable processors of a computing device to:
-
receive a first image and a second image; detect a facial gesture at least in part by determining whether a difference between the first image and the second image indicates a facial gesture; select, based at least in part on the detected facial gesture, the first image and the second image from among a plurality of images that includes at least the first image, the second image, and a third image; subsequent to selecting the first image and the second image, determine whether the first image and the second image are associated with a consistent identity, based at least in part on a similarity between the first image and the second image; and determine, based at least in part on detecting the facial gesture and on determining whether the first image and the second image are associated with the consistent identity, whether to deny authentication with respect to accessing one or more functionalities controlled by the computing device.
