Semantic monitoring of personal web activity to support the management of trust and privacy

For individual Web users, understanding and controlling their exchange of personal data is a very complex task as they interact, some-times unknowingly, with hundreds of dierent websites. In this paper, we present a set of tools and an experiment dedicated to monitoring a user's Web activity in order to build an observed model of his behavior in terms of the trust given to accessed websites and of the criticality of the data exchanged. By exposing such a model to the users and allowing them to interact with it, we provide ways for users to be better informed about their own behavior with respect to privacy, and ultimately, to better control their own data exchange
