Panagiotis Ilia

I am a Ph.D. candidate at the Computer Science Department, University of Crete, and a Graduate Research Assistant at the Distributed Computing Systems Lab (DCS), Institute of Computer Science (ICS), Foundation for Research and Technology - Hellas (FORTH).

My research interests lie within the broader area of web security and privacy. In the past few years I have focused my research on investigating the security limitations of online social networks, and exploring the privacy threats that users face mainly due to shared content. Recently I have also worked on designing efficient certificate revocation mechanisms and investigated the behavior and extent of malicious web proxies. Finally, my current projects aim at exploring the mechanics behind user tracking. Ultimately my research aims at identifying and understanding threats, and designing mechanisms for securing users.
