index.html   29) <h2>Tor: An anonymous Internet communication system</h2>

index.html   30) 
index.html   31) <p>

index.html   32) Tor is a toolset for a wide range of organizations and people that want

index.html   33) to improve their safety and security on the Internet. Using Tor can help
index.html   34) you anonymize web browsing and publishing, instant messaging, IRC, SSH,

index.html   35) and other applications that use the TCP protocol. Tor also provides a
index.html   36) platform on which software developers can build new applications with
index.html   37) built-in anonymity, safety, and privacy features.

index.html   41) Your traffic is safer when you use Tor, because communications

en/index.wml 42) are bounced around a distributed network of servers, called

en/index.wml 43) <a href="<page overview>">onion routers</a>.
en/index.wml 44) Tor's technology aims to provide Internet users with protection against
en/index.wml 45) "traffic analysis," a form of network surveillance that threatens personal
en/index.wml 46) anonymity and privacy, confidential business activities and relationships,
en/index.wml 47) and state security.

index.html   50) <p>

en/index.wml 51) Instead of looking at the content of your communications, traffic analysis
en/index.wml 52) tracks where your data goes and when, as well as how much is sent.
en/index.wml 53) <!--
en/index.wml 54) For example, online advertising companies like Doubleclick use traffic
en/index.wml 55) analysis to record what web pages you've visited, and can build a
en/index.wml 56) profile of your interests from that. A pharmaceutical company could
en/index.wml 57) use traffic analysis to monitor when the research wing of a competitor
en/index.wml 58) visits its website, and track what pages or products that interest the
en/index.wml 59) competitor. IBM hosts a searchable patent index, and it could keep a list
en/index.wml 60) of every query your company makes. A stalker could use traffic analysis
en/index.wml 61) to learn whether you're in a certain Internet cafe.

en/index.wml 65) -->
en/index.wml 66) Tor aims to make traffic analysis more difficult by preventing websites,
en/index.wml 67) eavesdroppers, and even the onion routers themselves from tracing your
en/index.wml 68) communications online. This means Tor lets you decide whether to identify
en/index.wml 69) yourself when you communicate.

index.html   70) </p>
index.html   71) 
index.html   72) <p>
index.html   73) Tor's security is improved as its user base grows and as

en/index.wml 74) more people volunteer to run servers.  Please consider

en/index.wml 75) <a href="<page volunteer>">volunteering your time</a> or
en/index.wml 76) <a href="<cvssandbox>tor/doc/tor-doc-server.html">volunteering your bandwidth</a>.

index.html   77) And remember that this is development code—it's not a good idea to rely

index.html   78) on the current Tor network if you really need strong anonymity.

en/index.wml 81) <p><b>We are now actively looking for new sponsors and funding.</b>

en/index.wml 82) The Tor project was launched by <a href="http://freehaven.net/">The Free
en/index.wml 83) Haven Project</a> in 2002. In the past, Tor development was funded
en/index.wml 84) by contracts with the <a href="http://www.nrl.navy.mil/">Naval
en/index.wml 85) Research Lab</a> (inventor of onion routing) and the <a
en/index.wml 86) href="http://www.eff.org/">Electronic Frontier Foundation</a> (who still
en/index.wml 87) kindly hosts our website). Sponsors of Tor get personal attention,
en/index.wml 88) better support, publicity (if they want it), and get to influence the
en/index.wml 89) direction of our research and development!
