\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: \\
Drexel, Univ of Waterloo, Georgia Tech, Princeton, Boston University, University College London, Univ of Minnesota, National Science Foundation, Naval Research Labs, Cambridge UK, Bamberg Germany, MIT...
\pause \item increasingly diverse toolset: \\
Tor, Tor Browser Bundle, Tails LiveCD, obfsproxy, Tor Weather, Tor auto-responder, Secure Updater, Orbot, Torora, Tor Check, Arm, Nymble, Tor Control, and so on.

\frametitle{Other Systems}
\begin{itemize}
\item VPN - Virtual Private Network, 1 to 1 connection, can redirect all traffic, generally encrypted
\pause \item Proxy - 1 to 1 connection, per application traffic redirection, sometimes encrypted
\pause \item I2P - Garlic routing, closed network, anonymity and reputation
\pause \item Freenet - closed network, anonymity, distributed file storage and sharing
\pause \item GNUnet - closed network, anonymity, distributed file storage and sharing

\item <3> \textit{Rights Activists}\\ Personal safety, family safety, narrowly-defined publicity, censorship circumvention
\item <4> \textit{Business Execs}\\ separating work from home life, competitor research, censorship circumvention
\item <5> \textit{Abuse Victims and Survivors}\\ complete separation of past abuse and current life, finding help and safety, need to help others anonymously
\item <6> \textit{Militaries}\\ intelligence gathering, separating work from home life, other activities
