1. The Onion Router (TOR)
TOR is a complex system allowing you to hide your true IP address via various online layers of anonymity, and this is why it is called Onion. As far as security is concerned, you don’t need to worry, because your data will be encrypted and re-encrypted many times, plus it will be sent via a succession of TOR relays. If you want to install and try TOR, visit https://www.torproject.org/ and download the app, which works on almost any OS – Windows, Apple and Linux/UNIX. Extract the archive and open the extracted folder to start browsing by double-clicking the “Start Tor Browser” executable. After you do so, you’ll see another window (the Vidalia Control Panel), together with an Internet browser demonstrating which IP address you’re currently using. In addition, the Vidalia Control Panel offers you a lot of features, like establishing your connection through TOR and appearance. You can also install the Torbutton for easier access.
