bringing many benefits but also the possibility of new threats. Privacy
 
is one of them. Nearly 70% of internet users are active in OSNs. On the
 
other hand, privacy breaches are keeping pace with this growth and
 
users' requirements are much higher than the privacy guarantees offered
 
by OSNs. In this talk, I present the current privacy protection
 
mechanism used in OSNs, the so called Relationship-based Access Control
 
(ReBAC), and pinpoint some of its weaknesses. Furthermore, I describe
 
the directions that are being considered to improve privacy protection
 
in OSNs. In particular, I focus on a formal privacy policy framework
 
(PPF), which uses knowledge-based logic to express complex privacy
 
policies and how these policies fix some of the problems in ReBAC.
 
Finally, I will show a prototype implementation of some PPF policies
 
(which are currently not offered in any commercial OSN, such as Facebook
 
or Twitter) in the open source OSN Diaspora*.
