+\frametitle{About Runa}
+\begin{itemize}
+\item Studied at the Norwegian University of Science and Technology
+\item Worked for the Tor Project during Google Summer of Code in 2009
+\item Developer, security researcher, translation coordinator
+\end{itemize}
+\end{frame}
+
+% And here's what we'll talk about
+\begin{frame}
+\frametitle{What are we talking about?}
+\begin{itemize}
+\item Crash course on anonymous communications
+\item Quick overview of Tor
+\item Usability, Security, and Humans
+\end{itemize}
+\end{frame}

+\frametitle{The Tor Project, Inc.}

+% Crash course on anonymous communications
+\begin{frame}
+\frametitle{What is anonymity?}
+\includegraphics[width=10cm]{../images/2llg3ts}
+\end{frame}
+
+\begin{frame}
+\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.
+\end{itemize}
+\begin{center}

+\frametitle{Anonymity isn't steganography}
+Attacker can tell Alice is talking to someone, how often, and how much data is sent.

+\end{frame}

+\begin{frame}
+\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}
+
+% What is Tor?
+\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, GetTor, Thandy, Orbot, Tor Check, Arm, Torouter, Tor Cloud
+and more
+\end{itemize}

+\frametitle{Bridges versus relays}
+\begin{itemize}
+\item A step forward in the blocking resistance race
+\item Bridge relays (or "bridges" for short) are Tor relays that aren't
+listed in the main Tor directory
+\item To use a bridge, you will need to locate one first (can be done
+using bridges.torproject.org, email, social media etc)
+\item A bridge will act as the first hop in the circuit
+\end{itemize}
+\end{frame}
+
+\begin{frame}
+\frametitle{Hidden services}
+\begin{itemize}
+\item Tor makes it possible for users to hide their locations while
+offering various kinds of services, such a website or an im server
+\item Using Tor "rendezvous points," other Tor users can connect to
+these hidden services, each without knowing the other's network identity
+\item A hidden service will have an address that ends in .onion, e.g.
+http://duskgytldkxiuqc6.onion/

+\frametitle{Anonymity, Usability, and Humans}
+\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.
+\end{itemize}

+\frametitle{Time for a demo}
+Demonstration of Tor Browser Bundle
+\end{frame}

+\begin{frame}
+\frametitle{Experience so far}
+\begin{itemize}
+\item Our web site is confusing to users and not technical enough for researchers.
+\pause \item The quality of translations can vary.
+\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.
+\end{itemize}
+\end{frame}
+
+\begin{frame}
+\frametitle{Next steps and how you can help}
+\begin{itemize}
+\item Test software.
+\item Provide feedback and suggest improvements.
+\item Help with development.
+\item Visit \url{https://www.torproject.org/} for more information, links, and ideas.
+\end{itemize}
