Projects
- LoKI: Location-based PKI for Social Networks
We use the ubiquity of mobile devices to allow users to verify OSN identities post-hoc after real-world meetings.
|
 |
- 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.
|
 |
- 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.
|
 |
- 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.
We exploit Triangle Inequality Violations to find faster paths to destinations in the Internet.
