Hi, everyone, welcome to the section, as we all know that in this session we are going to talk about
anonymity.
So before going into it, first list discussed at high level, some of the visible activities on the
Internet are being tracked.
So we won't go into all the parking meters or into too much details about any one matter.
So first, your IP address identifies you as you traverse the Internet, then data packet from your
machine is generally tagged with your IP address, making your activities easy to track.
Then second, Google and other email services will read your email address and emails and looking for
keywords to more efficiently serve you ads.
As we all know that everyone is doing this, although there are many more sophisticated matters that
are far more time and resource intensive.
These are the ones we try to prevent in this section.
So now let's start by taking a look at how IP addresses give us away on the Internet.
So when you send a packet of data across the Internet, it contains the IP addresses of the source and
destination for the data.
In this way, the packet knows where it is going and where to return the response.
So each packet hops through multiple Internet routers until it finds the destination and then goes back
to the sender.
So for the general Internet surfing, each hop is Rotel.
The packet passes through to get its destination.
Then there can be as many as 30 or we can say 20 to 30 between the senders and destination, but usually
any packet will find its way to the destination in fewer than 15 hops.
So as the package traverses the Internet, anyone intercepting the packets can see who send it, where
it has been and where it is going.
So this is one way a website can tell who you are and when arrive and log you in automatically.
And it's also how someone can track where you have been on the Internet.
So this is how basically the tracking works on the Internet.
So from the next election onwards, we are going to learn how we can break this mechanism.
