Two kinds of tasks within policy comprehensionSingle tasksCan friend A see my birthdate?Group tasksCan group of friends B see my pictures?2In my most recent project, we created a tool for privacy policy comprehension in online social networks.Main goal was to allow completion of group tasks, defined as..2Motivation (2)3Users mental models often involve natural subgroups (Fang and LeFevre 2010; Jones and ONeill 2010)Specific to a single users networkDesigned PViz to display communities to enable group tasks

Recently, studies have observed that users mental models of privacy in social networks often involve natural subgroups or communities.

We designed PViz to be aligned with this mental model to display a users privacy settings in terms of communities specific to their local network3PViz
