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.

Dependent claims

A method, comprising:

by a secure process of a device:
receiving, from a sensor in communication with a secure process, sensor data;
and
after receiving the sensor data:
in accordance with a determination that a first set of one or more criteria is satisfied, wherein the first set of one or more criteria includes a criterion that is satisfied when the device is currently in a first state, sending the sensor data to a system process of the device;
and
in accordance with a determination that a second set of one or more criteria is satisfied, wherein the second set of one or more criteria includes a criterion that is satisfied when the device is currently in a second state different from the first state, forgoing sending the sensor data to the system process of the device, wherein the second set of one or more criteria is different from the first set of one or more criteria.
