Tor (anonymity network) - Definition from the Hotspot Shield Glossary
Tor, otherwise known as the Anonymity Network or Onion Router is a form of software that enables users to engage in anonymous communication.
The Tor software uses a network of relay nodes that a user’s data passes through - Each node will encrypt the data and pass it on to the next node - To ensure that the data cannot be traced, each node is unaware of the previous or next node in the chain. This network of nodes is called the Tor network and is created by volunteers, and consists of over seven thousand relay nodes. In a standard connection, the user may obtain data directly from source - This can easily be traced back using IP addresses etc. The Tor network provides anonymity by creating a random and encrypted path for the data to flow, thus making it virtually impossible to trace any activity or connection back to the end user.
