en/torusers.wml    14) Tor was originally designed, implemented, and deployed as a third-generation
en/torusers.wml    15) <a href="http://www.onion-router.net/">onion routing project of the Naval Research Laboratory</a>,
en/torusers.wml    16) and was originally developed by and for the U.S. Navy for the primary purpose of protecting government communications.
en/torusers.wml    17) Today, it is used every day for a wide variety of purposes by the military, journalists, law enforcement officers, activists, and many others. Here are some of the specific uses we've seen or recommend.

en/torusers.wml    38) <li><strong>They protect their children online.</strong>

en/torusers.wml    39) You've told your kids they shouldn't share personally identifying information online, but they may be sharing their location simply

en/torusers.wml    40) by not concealing their IP address. Increasingly, IP addresses can be <a href="http://whatismyipaddress.com/">literally mapped to a city or even street location</a>, and can <a href="http://whatsmyip.org/more/">reveal other information</a> about how you are connecting to the Internet.

en/torusers.wml    41) In the United States, the government is pushing to make this mapping increasingly precise.

en/torusers.wml    57) <strong>Field Agents:</strong>
en/torusers.wml    58) It is not difficult for insurgents to monitor internet traffic and
en/torusers.wml    59) discover all the hotels and other locations from which people are
en/torusers.wml    60) connecting to known military servers.
en/torusers.wml    61) Military field agents deployed away from home have used Tor to
en/torusers.wml    62) mask the sites they are visiting, protecting military interests and
en/torusers.wml    63) operations, as well as protecting themselves from physical harm.

en/torusers.wml    66) <li><strong>Hidden services:</strong>

en/torusers.wml    67) When the Internet was designed by DARPA, its primary purpose was to be able to facilitate distributed, robust communications in case of
en/torusers.wml    68) local strikes.  However, some functions must be centralized, such as command and control sites.  It's the nature of the Internet protocols to
en/torusers.wml    69) reveal the geographic location of any server that is reachable online.  Tor's hidden services capacity allows military command and

en/torusers.wml    70) control to be physically secure from discovery and takedown.
en/torusers.wml    71) </li>

en/torusers.wml    72) <li><strong>Intelligence gathering:</strong>

en/torusers.wml    73) Military personnel need to use electronic resources run and monitored by insurgents. They do not want the webserver logs on an insurgent website

en/torusers.wml    74) to record a military address, thereby revealing the surveillance.

en/torusers.wml   106) Tor allows officials to surf questionable web sites and services
en/torusers.wml   107) without leaving tell-tale tracks.  If the system administrator of an

en/torusers.wml   109) government or law enforcement IP addresses in usage logs, investigations
en/torusers.wml   110) may be hampered.

en/torusers.wml   111) </li>

en/torusers.wml   112) <li><strong>Sting operations:</strong>

en/torusers.wml   113) Similarly, anonymity allows law officers to engage in online
en/torusers.wml   114) “undercover ” operations.  Regardless of how good an

en/torusers.wml   115) undercover officer's “street cred” may be, if the 
en/torusers.wml   116) communications include nypd.nyc.ny.state.us, the cover is blown.

en/torusers.wml   117) </li>

en/torusers.wml   118) <li><strong>Truly anonymous tip lines:</strong>

en/torusers.wml   119) While online anonymous tip lines are popular, without anonymity
en/torusers.wml   120) software, they are far less useful.  Sophisticated sources understand that
en/torusers.wml   121) although a name or email address is not attached to information, server
en/torusers.wml   122) logs can identify them very quickly.  As a result, tip line web sites that
en/torusers.wml   123) do not encourage anonymity are limiting the sources of their tips.

en/torusers.wml   130) <li><strong>Human rights activists use Tor to anonymously report abuses from

en/torusers.wml   132) forms of online and offline anonymity to organize workers in accordance
en/torusers.wml   133) with the Universal Declaration of Human Rights. Even though they are within

en/torusers.wml   137) <li>When groups such as the <strong>Friends Service Committee and environmental

en/torusers.wml   162) <li>In the US, the Supreme Court recently stripped legal protections from

en/torusers.wml   167) <li>A contact of ours who works with a public health nonprofit in

en/torusers.wml   168) Africa reports that his nonprofit <strong>must budget 10% to cover various sorts of corruption</strong>,
en/torusers.wml   169) mostly bribes and such.  When that percentage rises steeply, not only can they not afford the money, but they can

en/whousestor.wml 170) not afford to complain — this is the point at which open objection can

en/torusers.wml   174) <li>At a recent conference, a Tor staffer ran into a woman who came from

en/torusers.wml   175) a “company town” in the eastern United States. She was attempting to blog anonymously to rally

en/torusers.wml   176) local residents to <strong>urge reform in the company</strong> that dominated the town's
en/torusers.wml   177) economic and government affairs. She is fully cognizant that the kind of

en/torusers.wml   196) <li>Does being in the public spotlight shut you off from having a private

en/torusers.wml   197) life, forever, online?  A rural lawyer in a New England state keeps

en/whousestor.wml 198) an anonymous blog because, with the diverse clientele at his prestigious

en/torusers.wml   199) law firm, <strong>his political beliefs are bound to offend someone</strong>.  Yet, he

en/whousestor.wml 200) doesn't want to remain silent on issues he cares about.  Tor helps him
en/whousestor.wml 201) feel secure that he can express his opinion without consequences to his

en/torusers.wml   202) public role.
en/torusers.wml   203) </li>
en/torusers.wml   204) <li>People living in poverty often don't participate fully in civil society

en/whousestor.wml 205) -- not out of ignorance or apathy, but out of fear.  If something you
en/whousestor.wml 206) write were to get back to your boss, would you lose your job?  If your
en/whousestor.wml 207) social worker read about your opinion of the system, would she treat

en/torusers.wml   208) you differently?  Anonymity gives a voice to the voiceless.

en/torusers.wml   209) To support this, <strong>Tor currently has an open Americorps/VISTA position</strong> pending.  This

en/whousestor.wml 210) government grant will cover a full time stipend for a volunteer to create

en/torusers.wml   211) curricula to <strong>show low-income populations how to use anonymity online for
en/torusers.wml   212) safer civic engagement</strong>.  Although it's often said that the poor do not use

en/whousestor.wml 213) online access for civic engagment, failing to act in their self-interests,
en/whousestor.wml 214) it is our hypothesis (based on personal conversations and anecdotal
en/whousestor.wml 215) information) that it is precisely the “permanent record ”
en/whousestor.wml 216) left online that keeps many of the poor from speaking out on the Internet.

en/torusers.wml   217) We hope to show people how to engage more safely online, and then at

en/whousestor.wml 218) the end of the year, evaluate how online and offline civic engagement has

en/torusers.wml   227) Say a financial institution participates in a security clearinghouse

en/whousestor.wml 228) of information on Internet attacks.  Such a repository requires members
en/whousestor.wml 229) to report breaches to a central group, who correlates attacks to detect

en/whousestor.wml 232) traffic to such a repository to be able to track where information is

en/torusers.wml   233) coming from.  Even though every packet were encrypted, the IP

en/whousestor.wml 247) importance of traffic patterns, and the vulnerability of the surveillance

en/torusers.wml   252) In an age when irresponsible and unreported corporate activity has
