Abstract: In an embodiment, a device may include an attention detection service. The attention detection service may monitor various peripheral devices in the device for indications that a user is paying attention to the device. Various clients may register for notification of attention detection and attention lost (attention no longer detected) events, or may poll the service for the events. If a user is not paying attention to the device, it may be possible to take various actions to permit reduced energy consumption.

Abstract: A facial recognition authentication on a device having a camera may operate with multiple enrollment profiles on the device. Multiple enrollment profiles may include separate profiles for different appearances of a user and/or separate profiles for different users authorized to use the device. The enrollment profiles may be generated using an enrollment process where the enrollment process is operated separately to generate each of the different enrollment profiles. During the facial recognition authentication process, a user may unlock the device by having a matching score for image(s) captured of the user that that exceeds an unlock threshold for at least one of the enrollment profiles. The user may have a matching score that exceeds the unlock threshold for multiple enrollment profiles. Each enrollment profile unlocks the device for the user may be updated using a template update process that operates independently for each enrollment profile.

Abstract: Techniques are disclosed relating to biometric authentication, e.g., facial recognition. In some embodiments, a device is configured to verify that image data from a camera unit exhibits a pseudo-random sequence of image capture modes and/or a probing pattern of illumination points (e.g., from lasers in a depth capture mode) before authenticating a user based on recognizing a face in the image data. In some embodiments, a secure circuit may control verification of the sequence and/or the probing pattern. In some embodiments, the secure circuit may verify frame numbers, signatures, and/or nonce values for captured image information. In some embodiments, a device may implement one or more lockout procedures in response to biometric authentication failures. The disclosed techniques may reduce or eliminate the effectiveness of spoofing and/or replay attacks, in some embodiments.

Abstract: Techniques described herein provide efficient object detection and tracking in video images, such as may be used for real-time camera control in power-limited mobile image capture devices. The techniques include performing object detection on a first subset of frames of an input video, detecting an object and object location in a first detection frame of the first subset of frames, and tracking the detected object on a second subset of frames of the input video after the first detection frame.

Abstract: An orientation of an application user interface (e.g., text and/or content) on a display of a device may be determined by an orientation of the device relative to gravity. In situations where the orientation of the device relative to gravity does not provide a confident or accurate orientation for the application user interface, orientation of the application user interface may be determined from face orientation data. Face orientation data may be obtained from a face detection process operating on images of the user captured during a facial recognition process or during an attention detection process.

Abstract: When a device is successfully unlock using a facial recognition authentication process, feature vectors generated from images obtained during the facial recognition authentication process may be stored as temporary templates on the device. After a period of time, one of the temporary templates may be selected to be used as a “virtual” template for the device. For example, a median temporary template in the temporary templates may be selected as the virtual template. The performance of the virtual template may then be assessed over time and compared to the performance of templates generated from an enrollment process to determine if and how the virtual template is implemented on the device.
