Abstract
We hypothesize that, in a Facebook-style social network
system, proper visualization of one’s extended neighborhood
could help the user understand the privacy implications
of her access control policies. However, an unrestricted
view of one’s extended neighborhood may compromise
the privacy of others. To address this dilemma,
we propose a privacy-enhanced visualization tool, which
approximates the extended neighborhood 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.
