Have You Heard About Tor?

TOR: the Internet “anonymizer.”

For most of us what is personally important while using the Internet, is to have the best of:

  • Speed
  • Security
  • Access
  • Privacy

But there’s no such thing as the average person on the Internet; we’re all likely to have different priorities for different reasons.

  • As Internet users, we are as different as out personalities, work and personal responsibilities.
  • We also use the Internet different from each other based on our interests, obsessions, political affiliations and hobbies.

When privacy comes out on top.

However, there are many people who use the Internet and who definitely do not want to be identified by name on the Internet, at least when they are doing certain activities if not all the time. They would like to stay anonymous, as often as they can, online.

  • This isn’t simply a matter of not identifying themselves: they don’t want anyone to be able to track them down and find out who they are.
  • They also want to visit any type of website they want without anybody knowing about it and stopping them…no matter the content, whether it borders on being illegal or is even outright illegal.
  • They also want to say what they want, even if it’s not popular or raises concerns…and they don’t want to be put under surveillance, monitored, arrested or worse. (After all, freedom of expression changes depending on what country you’re in.)
  • Finally, they believe—with conviction, that we could be tracked down and identified very easily with the way the Internet and Web work today.

That’s where the very special Internet network known as Tor comes in for this crowd.

What is Tor?

As explained in the picture, Tor is a service that redirects Internet traffic through a special network which helps someone stay unidentifiable and unidentified online. Tor exists to keep an Internet user’s name and identity out of Internet activity (some or all) that they don’t want their true name and actual identity attached to.

Because, sometimes people simply want to communicate online, post messages and view websites in private, but are afraid to. That’s what Tor does, when the goal of these people is not to harm others.

What does Tor stand for?

Tor stands for The Onion Router, and it’s never spelled TOR or T.O.R., just so you know. It’s simply Tor.

Tor was developed in the mid 1990s by some computer scientists and a mathematician while working for the United States Naval Research Laboratory. They were tasked with coming up with a way to protect their Navy’s online intelligence communications.

Obviously, their goal wasn’t simply staying anonymous. They wanted to prevent others (an individual, organization or foreign country) from stealing and deciphering the Navy’s communications.

Tor made available to the public.

In the ensuing years, Tor transformed from a special network for sending secure military communications to a network that was open to the world at large. An Internet inside the Internet, so to speak.

This happened with the creation of The Tor Project, which was developed between 2002-2005, and founded by some of the original creators. However, by then there were several organizations who recognized that Tor offered something special—the ability for anyone in the world to use the Internet and send messages and email anonymously.

Tor became a beacon for privacy and free speech advocates.

Where does the “onion” idea come in?

If you’ve ever peeled apart an onion, you know it comes apart in layers. The computer engineers who created Tor chose a method that added layers of encryption over data that was going across a network.

Along with that, they ingeniously created special stops along the network, called relays, where a layer of encryption is pulled off, but just enough to get information the next relay destination. When the encrypted message arrives at the subsequent relay, the same thing happens—another layer is stripped and the message is moved on.

By the time the data reaches its destination, the last layer is peeled away and the information can be read. But everywhere along the way, nobody could see the data that was being transmitted. Not the contents and definitely not the IP address of the sender, which (if the person worked from one primarily locations) would identify where they were.

That also means if there were an intruder or hacker along the network, they wouldn’t be able to know who the sender was.

Tor today.

Today, Tor is vibrant and growing in popularity, and controversy. Tor is free, just like the Internet, and it moves Internet traffic from millions of users across a network of volunteer relays, numbering in the thousands.

However, as you start to look into Tor, be prepared. Because as you might expect, that level of freedom, which can be used for all the right reasons, is also abused by many people on the Internet…significantly…and for all the wrong reasons.

It all depends on what your perspective is on freedom of expression.
