In this paper, we propose ENTRUST, a system that enables users to authorize sensor operations that follow their input events, even if the sensor operation is performed by a program different from the program receiving the input event. Furthermore, proposed delegation methods do not enable users to control the use of their input events accurately. Researchers have proposed that programs should only be authorized to access system sensors on a user-approved input event, but these methods do not account for possible delegation done by the program receiving the user input event. However, untrusted programs may exploit interactions with other programs to obtain unauthorized access to system sensors either directly or through privileged services. Instead of placing all functionality into a single program, programs cooperate to complete tasks requested by users. Modern operating systems such as Android, iOS, Windows Phone, and Chrome OS support a cooperating program abstraction.
