Who Uses Tor?
The vast majority of Tor users are ordinary citizens who want to stay in control of their privacy online—
or censored users who need to circumvent Internet blockage. Criminals who are willing to break the law already have more effective options than using Tor.
Tor users can rely on the privacy of Tor. By design, a Tor relay operator or someone with physical access to a Tor relay cannot reveal a Tor user’s IP address. Continual peer review of Tor's source code by academic and open source communities ensures that there are no backdoors in Tor.
Tor is used by law enforcement agencies and investigators to monitor the web pages and services of suspects anonymously. By hiding investigators’ identities and locations, Tor can be a valuable tool for successful online undercover operations.

Alice encrypts her web page request to Bob three times and sends it to the first relay.
The first relay removes the first encryption layer but doesn't learn that the web page request goes to Bob.
The second relay removes another encryption layer and forwards the web page request.
The third relay removes the last encryption layer and forwards the web page request to Bob, but doesn't know that it comes from Alice.
Bob doesn't know that the web page request came from Alice, unless she tells him so.
