Abstract: The present disclosure generally relates to enrolling a biometric feature for use with a peripheral device. While a computer system is connected to an external device, the computer system receives a first request to enroll a biometric feature. In response to receiving the request and in accordance with a determination that the request satisfies a first set of one or more criteria, the computer system displays a user interface object prompting a user to provide an authorization input to one or more input devices physically connected to the computer system. While displaying the first user interface object, the computer system receives user input. In response to receiving the user input and in accordance with a determination that the user input includes the authentication input, the computer system initiates a process to enroll the biometric feature using a biometric sensor that is integrated with the external device.

Abstract: Techniques are disclosed relating to securing hardware accelerators used by a computing device. In some embodiments, a computing device includes one or more processors configured to co-execute trusted processes and untrusted processes in an isolated manner that includes implementing a secure environment in which a set of security criteria is enforced for data of the trusted processes. The computing device further includes multiple heterogenous hardware accelerators configured to implement exclaves of the secure environment that extend enforcement of one or more of the set of security criteria within the hardware accelerators for data distributed to the hardware accelerators for performance of tasks associated with the trusted processes.

Abstract: Techniques are disclosed relating to securing hardware accelerators used by a computing device. In some embodiments, a computing device includes a sensor and sensor processor circuitry coupled to the sensor. The sensor processor circuitry is configured to process sensor data received from a sensor of the computing device. In response to a first indication that a first consumer is trustworthy, the sensor processor circuitry is configured to provide a first data set of the processed sensor data to the first consumer. In response to a second indication that a second consumer is untrustworthy, the sensor processor circuitry is configured to negotiate one or more conditions in which the second consumer is permitted to receive a second data set of the processed sensor data.

Abstract: Techniques are disclosed relating to securing hardware accelerators used by a computing device. In some embodiments, a computing device includes user interface and user interface pipeline circuitry coupled to the user interface. The user interface pipeline circuitry is configured to process a set of data received from a first source to produce an output for the user interface of the computing device, receive, from a second source, an indication that a component of the computing device has been activated, and, prior to presenting the output via the user interface, insert, into the output, an indicator of the component being activated.

Abstract: Techniques are disclosed relating to devices that support biometric authentication. In various embodiments, a device includes a biosensor configured to collect biometric data from a user. An authentication system of the device is configured to perform a user authentication based on the collected biometric data. After performance of the user authentication, the authentication system receives sensor data indicating that the user remains collocated with the device and receives a request to confirm an authentication of the user. Based on the user authentication and the received sensor data, the authentication system confirms that the user has been authenticated. In various embodiments, the authentication system is configured to receive additional sensor data indicating that the user is no longer collocated with the device and, in response to a subsequent authentication request, require the user to perform another biometric authentication using the biosensor.

Abstract: Some techniques are described herein for providing a secure process to selectively provide different resolutions of sensor information to a system process of an operating system in response to different requests received by the system process from applications. For example, a sensor of a device can provide sensor data to a secure application of the device that performs one or more operations using the sensor data to generate metadata corresponding to the sensor data. In such an example, the secure application can provide the metadata to a filter layer of the device that also receives the sensor data and determines what resolution of the sensor data to send to an application of the device via a system process of an operating system of the device. Other techniques described herein include a filtering step at the system process.

Abstract: The present disclosure generally relates to methods and user interfaces for authentication, including providing and controlling authentication at a computer system using an external device in accordance with some embodiments.

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: 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.
