index.html   27) <h2>Tor: An anonymous Internet communication system</h2>

index.html   28) 
index.html   29) <p>

index.html   30) Tor is a toolset for a wide range of organizations and people that want

index.html   31) to improve their safety and security on the Internet. Using Tor can help
index.html   32) you anonymize web browsing and publishing, instant messaging, IRC, SSH,

index.html   33) and other applications that use the TCP protocol. Tor also provides a
index.html   34) platform on which software developers can build new applications with
index.html   35) built-in anonymity, safety, and privacy features.

index.html   39) Your traffic is safer when you use Tor, because communications

en/index.wml 40) are bounced around a distributed network of servers, called

en/index.wml 41) <a href="<page overview>">onion routers</a>.
en/index.wml 42) Tor's technology aims to provide Internet users with protection against
en/index.wml 43) "traffic analysis," a form of network surveillance that threatens personal
en/index.wml 44) anonymity and privacy, confidential business activities and relationships,
en/index.wml 45) and state security.

index.html   48) <p>

en/index.wml 49) Instead of looking at the content of your communications, traffic analysis
en/index.wml 50) tracks where your data goes and when, as well as how much is sent.
en/index.wml 51) <!--
en/index.wml 52) For example, online advertising companies like Doubleclick use traffic
en/index.wml 53) analysis to record what web pages you've visited, and can build a
en/index.wml 54) profile of your interests from that. A pharmaceutical company could
en/index.wml 55) use traffic analysis to monitor when the research wing of a competitor
en/index.wml 56) visits its website, and track what pages or products that interest the
en/index.wml 57) competitor. IBM hosts a searchable patent index, and it could keep a list
en/index.wml 58) of every query your company makes. A stalker could use traffic analysis
en/index.wml 59) to learn whether you're in a certain Internet cafe.

en/index.wml 63) -->
en/index.wml 64) Tor aims to make traffic analysis more difficult by preventing websites,
en/index.wml 65) eavesdroppers, and even the onion routers themselves from tracing your
en/index.wml 66) communications online. This means Tor lets you decide whether to identify
en/index.wml 67) yourself when you communicate.

index.html   68) </p>
index.html   69) 
index.html   70) <p>
index.html   71) Tor's security is improved as its user base grows and as

en/index.wml 72) more people volunteer to run servers.  Please consider

en/index.wml 73) <a href="<page volunteer>">volunteering your time</a> or
en/index.wml 74) <a href="<cvssandbox>tor/doc/tor-doc-server.html">volunteering your bandwidth</a>.

index.html   75) And remember that this is development code—it's not a good idea to rely

index.html   76) on the current Tor network if you really need strong anonymity.

en/index.wml 80) Tor was designed and developed by <a HREF="http://freehaven.net/">The
en/index.wml 81) Free Haven Project</a> and <a HREF="http://www.nrl.navy.mil/">NRL</a>
en/index.wml 82) as an <a HREF="http://www.onion-router.net/">onion routing</a> project.
en/index.wml 83) Previous funders include <a href="http://www.onr.navy.mil/">ONR</a>,
en/index.wml 84) <a href="http://www.darpa.mil/">DARPA</a>, and the <a
en/index.wml 85) HREF="http://www.eff.org/">Electronic Frontier Foundation</a> (who
en/index.wml 86) still kindly hosts our website). Sponsors of Tor get personal attention,

en/index.wml 87) better support, publicity (if they want it), and get to influence the

en/index.wml 88) direction of our research and development!</p>
