Visualizing Privacy Implications of Access Control Policies in Social Network Systems

Wehypothesizethat, inaFacebook-stylesocial networksystem, proper visualization of one’s extended neighbourhood could help the user understand the privacy implications of her access control policies. However, an unrestricted view of one’s extended neighbourhood may compromise the privacy of others. To address this dilemma, we propose a privacy-enhanced visualization tool, which approximates the extended neighbourhood of a user in such a way that policy assessment can still be conducted in a meaningful manner, while the privacy of other users is preserved.
