Hardware-assisted privacy protection using a secure user interface with multi-level access control of sensor data

摘要

Technologies provide hardware-assisted privacy protection of sensor data. One embodiment includes unlocking a user interface coupled to a trusted execution environment of a processor in a device, where the user interface includes a plurality of selectable settings associated with a plurality of access levels for sensor data captured by a sensor. The embodiment also includes receiving a selection signal from the user interface indicating that a user selected a first setting associated with a first access level for the sensor data captured by the sensor, and restricting access to the sensor data based on a first set of one or more entities associated with the first access level. In more specific embodiments, the user interface includes a knob that is rotatably attached to a housing of the device or a privacy panel including a slider bar that is to be displayed on a touch screen display of the device.
