  TrackMeNot is a Firefox plugin with laudable intentions - protecting your
privacy. By issuing a customizable stream of random search queries on its
users' behalf, TrackMeNot surmises that enough search noise will prevent its
users' true query profiles from being discerned. However, we find that
clustering queries by semantic relatedness allows us to disentangle a
nontrivial subset of true user queries from TrackMeNot issued noise.
