-% General flow:
-% internet is becoming centralized; good: cheaper to deploy, easier to manage; bad: control points, surveillance points
-% govt wants data, see total info awareness (wow, look at that logo or how to freak out your population) (give credit to moxie)
-% wiretapping the internet: mention some countries with programs about wiretapping, show nsa-room in AT&T San Fran
-% here's a better way to collect vast amounts of data about your population: show facebook logo
-% want more than just social interactions? show google logo, look at all of this data, email, instant messaging, topics of interest (search queries, results clicked, ads shown/clicked)
-% is absence of signal enough to arouse suspicion? cell phone location data, google services, facebook accounts?
-% how do you hide in a crowd without arousing suspicion? show tor headed liberty bell pic, don't be this guy

- \begin{columns}[t]
- \column{7cm}
-\begin{itemize}
-\item Conventional surveillance methods had to be targeted
-\item Internet censorship is capable of monitoring everyone, all of the time
-\item Governments are increasing monitoring: SORM (Russia), Golden Shield (China), Data Retention Directive (EU), and Interception Modernisation Programme (UK), Warrantless Wiretapping (USA)
-\item 1 in 7 East German citizens worked for the Stasi. Today we can achieve the same results with a fraction of the cost

-\frametitle{Traffic data surveillance}
-
-\begin{itemize}
-\item Traffic data (who talks to whom, how often and for how long) is the core of intelligence capabilities
-\item This information is cheaper to record and store, compared to full content
-\item Because it can be easily processed by computer, data mining techniques can be used to understand social structures
-\end{itemize}

-No longer true on a technical level: censorship is in the routers.

-
-Remains true on a social level: when material is censored, people distribute copies and draw attention to them

-But what if people are too afraid to do this?

-\begin{itemize}
-\item David Brin proposed that in a world of pervasive surveillance, balance could be maintained by allowing everyone to monitor everyone else
-\item Bruce Schneier retorted that surveillance amplifies existing powers
-\item Many countries restrict anonymous speech (e.g.\ Germany and China)
-\item It is easy for those in power to call on the weak to link their names to opinions

-\frametitle{Censorship resistance systems}
-\begin{itemize}
-\item Software to resist censorship should
-\begin{itemize}
- \item have a diverse set of users
- \item work where you are without special steps
- \item be sustainable (what if the company goes broke?)
- \item be decentralized (swapping censors doesn't help you)
- \item protect you by default
- \item have accessible standards and published designs (black box vs. glass box)
- \item be fast enough that you'll use it daily
- \item doesn't promise perfect everything including a fully encrypted Internet
-\end{itemize}
-\item<1-> These properties should be maintained even if the censorship resistance system is partially compromised
-\end{itemize}
-\end{frame}

-\begin{frame}
-\frametitle{Blocking with technology}
-\begin{itemize}
-\item When a country's government controls international connectivity, they can block requests for banned websites and destinations
-\item There are a number of different approaches (DNS blocking, IP address blocking, etc.)
-\item Software may be produced in-country, but often is an adapted commercial product
-\item These companies not only make the software, but provide a continuously updated list of websites to be blocked
-\end{itemize}

-\frametitle{Trade-offs in blocking systems}
-\begin{itemize}
-\item<1-> DNS blocking
-\begin{itemize}
-\item Easy and cheap to implement
-\item Blocks at domain name granularity -- over blocks protocols, web pages
-\item Trivial to bypass
-\end{itemize}
-\item<2-> IP blocking
-\begin{itemize}
-\item Easy and cheap to implement
-\item Blocks at IP address (perhaps port) -- over-blocks virtual hosting
-\end{itemize}
-\item<3-> Proxy blocking
-\begin{itemize}
-\item Expensive to implement
-\item Blocks at webpage level -- low over-blocking
-\end{itemize}
-\item<4-> Hybrid blocking -- IP based redirection to proxy
-\begin{itemize}
-\item Tricky to get right, but cheap
-\item Has some vulnerabilities
-\item Blocks at webpage level -- low over-blocking
-\end{itemize}
-\end{itemize}

-\frametitle{Who wants online privacy?}
-\begin{itemize}
-\item<1-> Ordinary people
-\begin{itemize}
-\item To avoid personal information being sold to marketers
-\item Protect themselves when researching sensitive topics
-\end{itemize}
-\item<2-> Military and Law Enforcement
-\begin{itemize}
-\item To carry out intelligence gathering
-\item Protect undercover field agents
-\item Offer anonymous tip lines
-\end{itemize}
-\item<3-> Journalists
-\begin{itemize}
-\item To protect sources, such as whistle blowers
-\end{itemize}
-\item<4-> Human rights workers
-\begin{itemize}
-\item To publicize abuses and protect themselves from surveillance
-\item Blogging about controversial subjects
-\end{itemize}
-\item<5-> Businesses
-\begin{itemize}
-\item To observe their competition and build anonymous collaborations
-\end{itemize}
-\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{Tor is a low-latency anonymity system}
-\begin{itemize}
-\item<1-> Based on technology developed in the Onion Routing project
-\item<2-> Privacy by design, not by policy (no data collected)
-\item<3-> Commonly used for web browsing and instant messaging (works for any TCP traffic)
-\item<4-> Originally built as a pure anonymity system (hides who is talking to whom)
-\item<5-> Now designed to resist censorship too (hides whether someone is using the system at all)
-\item<6-> Centralized directory authorities publish a list of all servers; client doesn't trust the network by design
-\end{itemize}

-\frametitle{Limitations of censorship resistance}
-\begin{itemize}
-\item Censorship resistance is thought controversial -- especially by the censors
-\item There is something for everyone to like, and something for everyone to dislike, going on with censorship resistance systems
-\item Bad people do use them to do bad things (for many different definitions of bad people)
-\item It is impossible to block bad uses, even if we could come up with a common definition of bad content
-\item The systems are not perfect, so it is possible some people will be caught
-\end{itemize}
-\end{frame}

-\frametitle{Conclusions}
- \begin{columns}[t]
- \column{7cm}
- \begin{itemize}
- \item The Internet and centralisation can both improve and harm freedom of speech
- \item Slogans regarding the borderless nature and inherent freedoms of the Internet are frequently wrong
- \item Technical details matter: how a system is implemented can make a radical difference
- \item Technologies can be used to resist censorship and improve privacy
- \item However, policies must be changed too and pressure is needed on legislators

-\frametitle{One Version of the Future}
-\begin{quotation}
-\noindent \includegraphics[width=1cm]{./images/opquo}\quad I'd like to change the design of the Internet by introducing
-regulation--Internet passports, Internet police and international
-agreement--about following Internet standards. And if some countries
-don't agree with or don't pay attention to the agreement, just cut
-them off.

-\medskip
-\begin{quotation}
-\noindent \includegraphics[width=1cm]{./images/opquo}\quad
-We think it's something you cannot live without in modern society. Like banking services or water or electricity, you need an Internet connection

-\textbf{Tor Project's Mission}

-\begin{quotation}
-\noinent \includegraphics[width=1cm]{./images/opquo}\quad We remain committed to defending online privacy and anonymity as a human right.
-\end{quotation}
-\end{frame}
-
-\begin{frame}
-\frametitle{How to get there}
-\begin{itemize}
-\item Increased funding of research and development for privacy, circumvention, and anti-censorship technologies
-\item Policy and Legal frameworks for free access, free speech, and anonymity
-%\item Mobile devices and telco innovation
-%\item Ambient connectivity
