Abstract
Generally, this disclosure describes devices, methods and systems for securely providing context sensor data to mobile platform applications. The method may include configuring sensors to provide context data, the context data associated with a mobile device; providing an application programming interface (API) to a sensor driver, the sensor driver configured to control the sensors; providing a trusted execution environment (TEE) operating on the mobile device, the TEE configured to host the sensor driver and restrict control and data access to the sensor driver and to the sensors; generating a request for the context data through the API, the request generated by an application associated with the mobile device; receiving, by the application, the requested context data and a validity indicator through the API; verifying, by the application, the requested context data based on the validity indicator; and adjusting a policy associated with the application based on the verified context data.
