Title:
MITIGATION OF SENSOR-BASED COVERT CHANNELS IN MOBILE DEVICES
Document Type and Number:
WIPO Patent Application WO/2017/197554
Kind Code:
A1
Abstract:
Technologies are generally described to mitigate of sensor-based covert channels. In some examples, a foreground application may cause particular interactions with a device sensor to occur, where the interactions may encode potentially sensitive information. A background application may then attempt to retrieve the interactions from the device sensor and leak the encoded information. In order to address this, a sensor virtualization module may restrict background application access to the sensor, for example by preventing sensor access or by providing intentionally-degraded sensor data to background applications.
