Locking and unlocking a mobile device using facial recognition
First Claim
1. A non-transitory machine readable medium including instructions which, when executed by one or more processors, cause the one or more processors to perform operations to lock a mobile device having a camera, the operations comprising:
- while the mobile device is unlocked and in response to detecting that the mobile device has been motionless for a threshold period, capturing one or more images using a low power operational mode of the camera, wherein detecting that the device has been motionless includes detecting movement and orientation of the device using an inertial sensor;
analyzing the images to determine whether a face appears in the one or more images; and
locking the mobile device in response to determining that the face does not appear in the one or more images for the threshold period.

Abstract
In an embodiment of the invention, an unlocked mobile device is configured to capture images, analyze the images to detect a user'"'"'s face, and automatically lock the device in response to determining that a user'"'"'s face does not appear in the images. The camera capturing and face recognition processing may be triggered by the device having detected that it has been motionless for a threshold period of time. In another embodiment, a locked mobile device is configured to capture an initial image using its camera, capture a new image in response to detecting movement of the device, determine that the device moved to a use position, capture a subsequent image in response to determining that the device moved to a use position, analyze the subsequent image to detect a user'"'"'s face, and unlock the device in response to detecting the user'"'"'s face. Other embodiments are also described and claimed.

21. A system to lock a mobile device having a camera, the system comprising:
-
a non-transitory machine-readable storage device; and one or more processors coupled to the non-transitory machine-readable storage device, the one or more processors to execute instructions stored in the storage device to perform operations while the mobile device is unlocked, the operations including; in response to detecting that the mobile device has been motionless for a threshold period, capturing one or more images using a low power operational mode of the camera, wherein detecting that the device has been motionless includes detecting movement and orientation of the device using an inertial sensor; analyzing the images to determine whether a face appears in the one or more images; and locking the mobile device in response to determining that the face does not appear in the one or more images for the threshold period. - View Dependent Claims (22, 23, 24, 25, 26, 27)
