Hello Everyone,

My name is Sherief and I am one of the Tor Project support team. In this short video, I am going to speak about anonymity using Tor, how it works, what it does and does not provide.

To understand how Tor protects your privacy and anonymity on the Internet I have to first explain how a normal browser works.

In this example, I will be using "example.com" which is a fictional website but you can remove "example" and put any website name instead.

Let’s say you open your laptop then fire up a web browser (like Chrome, Firefox or Safari) and visit example.com.

Your browser will send an unencrypted request to your ISP to get example.com's homepage. Because the request is unencrypted, anyone between you and example.com will know which
websites you visit, when you visit them, how often, your username, password and physical location.

Another problem with browsing the Internet without being anonymous is called “data retention”. Some websites will retain a lot of data about you and your activities on their websites and this data can be used for a variety of purposes. For example: creating tailored ads for you.

As you can see this way of browsing the Internet threatens your privacy and anonymity. Let’s how Tor tries to solve this problem.

Before I start, here is an advise: Use HTTPS. The purpose behind it is to enable you to browse the internet securely with all the data transferred being encrypted so that it cannot be read by anyone except the recipient.
You can check if the website is using HTTPS or not from the address bar in your browser. HTTPS has the same effect whether you use Tor or not.

When you try to visit https://www.example.com/ through Tor, the same process I’ve explained in the previous slide happens but with some extra steps.

Instead of using your normal browser, you will use one that the Tor Project provides "The Tor Browser Bundle".Through the Tor browser bundle visit the HTTPS version of example.com. Tor Browser will encrypt your request then send it to your ISP (which will not be able to identify the content of your request). Then, your ISP 
will forward your request to the first Tor relay (aka the Guard relay). Next, the guard relay will forward to the second relay (or the middle relay). After that, the second relay will forward to the 3rd Tor relay (aka the exit relay). Finally, your request leaves the Tor network and reaches example.com (which will not identify your real IP because to it you will appear as the last Tor relay).

With this, you become anonymous on the internet and ensure your request stays private while it's traveling through internet to its destination.
