Query: Differentiated context-aware hook placement for different owners'
  smartphones   A hook is a piece of code. It checks user privacy policy before some
sensitive operations happen. We propose an automated solution named Prihook for
hook placement in the Android Framework. Addressing specific context-aware user
privacy concerns, the hook placement in Prihook is personalized. Specifically,
we design User Privacy Preference Table (UPPT) to help a user express his
privacy concerns. And we leverage machine learning to discover a Potential
Method Set (consisting of Sensor Data Access Methods and Sensor Control
Methods) from which we can select a particular subset to put hooks. We propose
a mapping from words in the UPPT lexicon to methods in the Potential Method
Set. With this mapping, Prihook is able to (a) select a specific set of
methods; and (b) generate and place hooks automatically. We test Prihook
separately on 6 typical UPPTs representing 6 kinds of resource-sensitive UPPTs,
and no user privacy violation is found. The experimental results show that the
hooks placed by PriHook have small runtime overhead.
