So what is store tour is short for the onion router and it's basically a network of computers or servers
designed to improve anonymity and privacy.
It's the most common and an amazing network with the most amount of users and it also allows connected
users to offer hidden services or online services.
So these are basically deep net or darknet Web sites and that's what most people refer to when they're
talking about darknet or the deep net Web sites.
Even though it could mean many other anon amazing networks and hidden services networks I should also
note that Tor relies on online routing.
This is a technique that was designed by the US Army in order to protect their intelligence communications.
You might want to use Tor even if you don't want to access the deep net.
You can literally just use it if you want to protect your privacy and anonymity.
So while you might want to do that well let's see what happens when you connect to our Web site.
So let's say for example you open your browser and you navigate to Google dot com or Facebook dot com
by default without really doing or trying anything.
These Web sites will be able to see your location your browser version your operating system and much
more information.
And it doesn't stop there for example because you use google to search for a lot of things.
Google can see everything you search right now and even everything that you searched before.
Not only that but again big Web sites such as Google and Facebook.
They can even potentially access your activity outside of these Web sites.
They use this relying on the features they offer to other Web sites.
For example any Web site that would have a Google or a Facebook share button would have a piece of code
from Google or from Facebook running on their Web site.
And again Google and Facebook use this code in order to see which websites you visit.
And obviously they use that in order to serve you ads related to you we all know that you search for
something and you start seeing it everywhere else but it doesn't stop there.
We've all read the Cambridge analytics scandal and how they were able to access private information
about Facebook users.
And it doesn't even stop at this.
There are several reports reporting that Web sites such as Facebook creates ghost profiles so profiles
for people that don't even have a Facebook account.
So you might think OK I don't have a Facebook account.
They can't really track me.
No they still probably have a profile about you because like I said any Web site that you visit that
has a Facebook like button or a Facebook share button will collect data about you.
And Facebook is not going to stop there.
They will create a profile.
They'll add some name to it or some identity to it and they'll have all the things related to you what
you like what websites you visit.
What did you purchase recently.
And one this is only what's been reported so you can only imagine what's happening without getting caught.
And without being reported so what's the solution.
Well Toure is actually a pretty good solution to prevent this.
So when you connect to Tor you can imagine Toure being this really big network and it has a large number
of servers so each circle in here is literally server and detour network.
So you'll connect to tour and let's say you want to go to Google dot com.
What's going to happen is your request is going to bounce over three different servers or three different
nodes before it goes to Google.
So Google can only see the last node or the last server or the last computer that the request was sent
from.
It can't see you or the original user.
Keep in mind that these servers are shared.
So at any point of time there would be millions of users using data or network.
So there would be lots of requests going in and out of each node.
So when you're going into this node you're not the only user access in this node so there are lots of
requests coming in and out of here.
Same in here and same in here.
So this node could potentially be sending thousands of requests out to a number of Web sites.
Therefore wherever Web site these requests are going to it is very hard for it to profile that request
or to know where that request came from.
Also that sent within the Tor network is always encrypted so you can see the green arrows in here.
These represent encrypted data and the only two times where your data is sent unencrypted is the Red
Arrows.
So it's when you try to send something to the terror network and it's when data leave the Tor network
this arrow right here is not very important because if the Target's website uses hash TTP as or if you're
using a browser plugin that forces a TTP as then this data right here will be encrypted by hasty CPS
by SSL.
So the only point where your data is sent unencrypted is when you're sending data to tour.
Also keep in mind whenever you're sending data to Tor even to your Internet service provider they can
see that you're trying to access tor but they want to be able to see the Web sites you're trying to
access.
So all they'll be able to see is this person right here is trying to access tor but they won't really
be able to see that you're trying to go to Google dot com.
So even if there was a hacker or even if there was censorship in place then you really want to be able
to see which websites you're going to.
They'll only be able to see that your access in detail network.
