The advancement of communication technologies such as the Internet, mobile communications, wireless networks and online platforms has eased the exchange of information between individuals: it has enabled collection of large amounts of personal data at an ever-increasing rate. In this talk we focus on two use cases: the interdependent privacy on Facebook and the privacy issues of car sharing systems.

First, I will present a comprehensive analysis of and countermeasures for the interdependent privacy problem on Facebook; providers of third-party applications on Facebook exploit the interdependency between users and their friends. Second, I will present the privacy issues on car sharing systems; owing to the massive amounts of personal information, rich information about individuals' everyday lives and habits can be extracted, enabling profiling. Finally, I will present a fully-fledged privacy-enhancing protocol (sketch) for car access provision as a solution design.

Iraklis Symeonidis is a PhD candidate at COSIC of KU Leuven, supervised by Prof. Bart Preneel. He holds a master’s degree in Digital Systems Security from the University of Piraeus, and an engineering degree in Information and Communication Engineering from the University of the Aegean. He was a visiting researcher at CrySyS Lab of BME, recipient of an FWO grant. His current research interests fall in the intersection between information security and privacy with a specific focus on security by design and privacy by design. Currently, he is working on solutions for private information sharing in online social networks and connected cars.
