Abstract

In this paper, we introduce Facet, an unobservable transport service for social video sites. Facet evades detection by Internet censors by streaming social videos over Skype calls, and applying a novel traffic-analysis countermeasure called video morphing. We report on the performance and security of a prototype implementation of Facet and find that a single Facet server can support roughly 20 si-multaneous sessions, while providing strong unobservability: using the best known traffic analysis methods, a censor seeking to block 90% of Facet calls would need to block over 40% of all Skype calls. An additional benefit of our prototype implementation is that it avoids the distribution problem: clients can use Facet without installing any additional software.
