Reed and David Goldschlag, to protect U.S. The core principle of Tor, Onion routing, was developed in the mid-1990s by United States Naval Research Laboratory employees, mathematician Paul Syverson, and computer scientists Michael G. Tor's intended use is to protect the personal privacy of its users, as well as their freedom and ability to conduct confidential communication by keeping their Internet activities unmonitored.
Using Tor makes it more difficult to trace the Internet activity to the user. It directs Internet traffic through a free, worldwide, volunteer overlay network, consisting of more than six thousand relays, for concealing a user's location and usage from anyone conducting network surveillance or traffic analysis. Tor, short for The Onion Router, is free and open-source software for enabling anonymous communication.
