| − | Online Social Networks (OSNs) have changed the way people communicate,
| + | T.B.A. |
| − | 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*.
