+\frametitle{Anonymity isn't cryptography}
+\begin{itemize}
+\item Cryptography protects the contents in transit
+\item You still know who is talking to whom, how often, and how much data is sent.

+\frametitle{Anonymity isn't just wishful thinking...}
+\begin{itemize}
+\item "You can't prove it was me!"
+\pause \item "Promise you won't look"
+\pause \item "Promise you won't remember"
+\pause \item "Promise you won't tell"
+\pause \item "I didn't write my name on it!"
+\pause \item "Isn't the Internet already anonymous?"
+\end{itemize}
+\end{frame}
+
+\begin{frame}
+\frametitle{..since "weak" isn't anonymity.}
+\begin{itemize}
+\item<1> \textit{"You can't prove it was me!"}  Proof is a very \textbf{strong} word.  Statistical analysis allows suspicion to become certainty.
+\item<2> \textit{"Promise you won't look/remember/tell"}  Will other parties have the abilities and incentives to keep these promises?
+\item<3> \textit{"I didn't write my name on it!"}  Not what we're talking about.
+\item<4> \textit{"Isn't the Internet already anonymous?"}  Nope!
+\end{itemize}
+\end{frame}
+
+\begin{frame}
+\frametitle{Anonymous communication}
+\begin{itemize}
+\item People have to hide in a crowd of other people ("anonymity loves company")
+\item The goal of the system is to make all users look as similar as possible, to give a bigger crowd
+\item Hide who is communicating with whom
+\item Layered encryption and random delays hide correlation between input traffic and output traffic
+\end{itemize}
+\end{frame}
+
+\begin{frame}
+\frametitle{Low-latency versus High-latency anonycomm systems}
+\begin{itemize}
+\item Tor is not the first system; ZKS, mixmaster, single-hop proxies, Crowds, Java Anon Proxy.
+\item Low-latency systems are vulnerable to end-to-end correlation attacks.
+\item High-latency systems are more resistant to end-to-end correlation attacks, but by definition, less interactive.
+\end{itemize}
+\end{frame}
+
+\begin{frame}
+\frametitle{Low-latency systems are all the rage}
+\begin{itemize}
+\item<1> Interactive apps: web, instant messaging, VOIP, ssh, X11, cifs/nfs, video streaming (millions of users)
+\item<1> Multi-hour delays: email, nntp, blog posting? (tens of thousands of users?)
+\item<2> \begin{center}\begin{Large}And if anonymity loves company...\end{Large}\end{center}
+\end{itemize}
+\end{frame}

+\begin{frame}
+\frametitle{What is Tor?}
+\begin{itemize}
+\item online anonymity software and network
+\pause \item open source, freely available (3-clause BSD license)
+\pause \item active research environment: \\
+Rice, UMN, NSF, NRL, Drexel, Waterloo, Cambridge UK, Bamberg Germany, Boston Univ, Harvard, MIT, RPI, Georgia Tech
+\pause \item increasingly diverse toolset: \\
+Tor, Torbutton, Tor Browser Bundle, TAILS Anonymous Operating System, Tor Weather, Tor auto-responder, Secure Updater, Orbot, Torora, Tor Check, Arm, Nymble, Tor Control, Tor Wall, TorVM

+\begin{itemize}
+\item Allow the user to fully configure Tor rather than manually searching for and opening text files.
+\item Let users learn about the current state of their Tor connection, and configure or find out whether any of their applications are using it.
+\item Make alerts and error conditions visible to the user.
+\item Run on Windows, Linux, and OS X, on a normal consumer-level machine.

+\frametitle{Experience so far}
+\begin{itemize}
+\item Our web site is confusing to users and not technical enough for researchers.
+\pause \item Concepts of anonymity and its threats escape most users.\\"I want my Youtube!"  "I use tor to organize on facebook."
+\pause \item Cultural differences and their expectations of software, usability, anonymity, privacy, and what tor provides.
+\pause \item Software leaks data all over the place.  Stopping these leaks leads to unexpected user experiences.
+\pause \item Five years since we last dabbled in Usability.
