When you use the Internet, you are being tracked. The web- sites which you visit know who you are; marketers track your behaviour and your preferences. Even criminals exploit the traces people leave online. Anonymous communication sys- tems help defeat such monitoring. One such system, Tor, is used by over 500,000 people daily including law enforcement, human rights workers, military personnel, and ordinary citi- zens worldwide. While originally designed for enhancing pri- vacy and safety, Tor is increasingly used for allowing its users to circumvent censorship, and access commonly blocked web- sites including social networking, reference and news. Anony- mous communication systems introduce some unique chal- lenges, but many of the problems faced by the Tor network mirror those which are found on the wider Internet. For this reason, the study of Tor and similar systems will be infor- mative in general, and allow the testing of hypotheses which would be difficult to evaluate on larger systems.
