(PDF) Projects Persona: Privacy-Enabling aRchitecture for SOcial Networking Applications We give users flexible privacy controls over their OSN data that even protect the contents of the data from the OSN itself. Bond Breaker: Secure In-Band Public Key Exchange on Online Social Networks We study whether users are able to identify each other in-band by relying on rich out-of-band information that is implicit in OSN links. GeoMAN: IP Geolocation on Metropolitan Area Networks We geolocate IP addresses specifically in the context of a metropolitan area to get more precise results than in WAN geolocation. PeerWise We exploit Triangle Inequality Violations to find faster paths to destinations in the Internet. evilTwin We use multiple, disjoint Chord rings to prevent malicious nodes from usurping a DHT.
