The third group of users represents the dark side of Tor. To give another example, even CIA has established an onion site to allow anyone to communicate or send information in secrecy and anonymity. Or, other organizations like Facebook and The New York Times have their own onion sites to provide security and anonymity to their users or to the whistleblowers. For instance US Navy, as the developer of the project, is still a key user. Ordinary users, as well as the activists and journalists who want to evade censorship in some countries can also be counted in this first group.Īs a second group, governments and institutions can also benefit from using Tor. The first group consists of ordinary people who want to protect their Internet activity from observing eyes or advertisers. These users mainly fall into three groups. As of this post’s date, approximately, more than 40 million people are using Tor world wide. Who Uses Tor?Īfter NSA surveillance revelations in 2013, the number of people using Tor has increased tremendously. After its public release in 2002, it has transformed into what is now known as Tor Project, an open source anonymity service project. The project was mostly funded by the US State Department and Department of Defense (DoD), though there were other supporters too, such as Electronic Frontier Foundation, Knight Foundation, and Swedish International Development Cooperation Agency. Tor (The Onion Router) was developed during the early 2000s by Naval Research Lab and the Defense Advanced Research Projects Agency (DARPA). In addition to surfing anonymously and in secrecy, Tor also allows for hosting specially designed hidden web sites, a.k.a., onion sites, that are accessible only through Tor network. Additionally, encrypting data multiple times in layers further prevents prying eyes from eavesdropping and analyzing your data. This mechanism of exchanging traffic over a number of onion routers makes it extremely hard for anyone to identify the source of the information. onion routers, are non-proprietary and operated by thousands of volunteers around the world. Fundamentally, it hides the IP addresses of its users (anonymity) in addition to encrypting (secrecy) the traffic while browsing online. Tor achieves this privacy and security by routing Internet traffic through specially crafted relays that encrypts and decrypts transient data in a layered fashion. #What is tor in cyber security softwareTor (short for The Onion Router) is an open source project and a free software that aims to provide online privacy and anonymity for browsing the Internet.
