Abstract: Apparatus and methods for restricting egress of sensor data from a feature detection process to an interactor process. The sensor data can include audio data, image data, location data, and/or other sensor-based data. The feature detection process is sandboxed to restrict the egress of data from the component. Once the feature detection process determines that a feature has been detected in sensor data, the interactor process can be provided with the sensor data and/or additional sensor data. The sensor data and/or the additional sensor data can be provided directly by an operating system and not via the feature detection process. In some implementations, a notification can be rendered once data is sent to the interactor process. The notification can indicate that the sensor data is being accessed. Rendering of the notification can be suppressed when only the sandboxed feature detection process is accessing the sensor data.
