+\item Blocks at webpage level -- low overblocking

+\frametitle{Tor is a low-latency anonymity system}
+\begin{itemize}
+\item Based on technology developed in the Onion Routing project
+\item Commonly used for web browsing (works for any TCP traffic)
+\item Originally built as a pure anonymity system (hides who is talking to whom)
+\item Now designed to resist censorship too (hides whether someone is using the system at all)
+\item Centralised directory authorities publish a list of all servers
+%%\item (First version developed as Part II project by Matej Pfajfar)
