Determining user privacy preferences by asking the right questions

Abstract

One fundamental aspect of user privacy is to respect the privacy preferences that users have. A clear prerequisite to doing this is accurately gauging what user's privacy preferences are. Current approaches either offer limited privacy options or have so many choices that users are likely to be overwhelmed. We present a framework for modeling user privacy preferences in terms of a hierarchy of questions which can be asked. We describe two means of dynamically choosing which questions should be asked to efficiently determine what a user's privacy preferences are.
