Ensuring privacy of users of social networks is probably an unsolvable
conundrum. At the same time, an informed use of the existing privacy options by
the social network participants may alleviate - or even prevent - some of the
more drastic privacy-averse incidents. Unfortunately, recent surveys show that
an average user is either not aware of these options or does not use them,
probably due to their perceived complexity. It is therefore reasonable to
believe that tools assisting users with two tasks: 1) understanding their
social net behavior in terms of their privacy settings and broad privacy
categories, and 2)recommending reasonable privacy options, will be a valuable
tool for everyday privacy practice in a social network context. This paper
presents YourPrivacyProtector, a recommender system that shows how simple
machine learning techniques may provide useful assistance in these two tasks to
Facebook users. We support our claim with empirical results of application of
YourPrivacyProtector to two groups of Facebook users.
