Fuente: Wipo "Sensorization" 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.
