Anonymous opinion exchange over untrusted social networks
Mouna Kacimi, Stefano Ortolani, Bruno Crispo · 2009
Social networks are the fastest growing Internet applications. They offer the possibility to get in touch with current friends, discover where the old ones are, and make new ones. While these applications are a great enabler for our social life, they are also well known to fall short on privacy. The lack of adequate privacy enhancing technology is particularly important in these applications due to the nature of information they deal with, and the fact that many users are underage. This paper provides a contribution in this direction by presenting a protocol, tailored for social network applications, that allows users to ask and/or submit personal opinions while preserving their anonymity.
