Tor - short for The Onion Router - is a seething matrix of encrypted websites that allows users to surf beneath the everyday internet with complete anonymity.
It uses numerous layers of security and encryption to render users anonymous online.
Normally, file sharing and internet browsing activity can be tracked by law enforcement through each user's unique IP address that can be traced back to an individual computer.
The Tor network hides the IP address and the activity of the user.
Most of the Web's information is buried far down on dynamically generated sites, unable to be found or seen by traditional search engines - sites or pages don't exist until created as the result of a specific search.
An Internet search is like dragging a net across the surface of the sea - a great deal of information is caught, but a majority is deep and therefore missed.
