Right below the surface of where the iceberg meets underwater is the deep web. It’s comprised of the same general hostnames as sites on the surface web, but along with the extension of those domains. This is the specific URL of your Facebook Messenger thread with a friend, or the Department of Justice’s public archival material, or Harvard’s internal communications system. The deep web is the majority of the internet as a whole.

2. Internet is divided in two parts:
1. Surface Web
(Represents only 4% of all that exists and we know on the internet)
2. Deep Web
(Represents 96% remaining)
This information is not always available for us.
We can found :

3. What is Surface Web?
Webpages with static or persistent URLs
that can be detected by a search engine
crawler.
Once detected the URL is added to that
search engine’s database and can become a
result in a query or search of that search
engine.

4. What is Deep Web?
The Deep Web is the “hidden” part of the web.
Inaccessible to conventional search engines, and
consequently, to most users.
Sometimes called the “Invisible Web”, includes
information contained in searchable databases that
can only be reached by a direct query or a
specialized search engine.
Information is contained in dynamic WebPages
that are generated upon request to a database. It
has no persistent or static URL.

6. How to access Deep web ?
This place is actually in the internet world, but you cannot access
this by using the normal browser, it’s not secure way.
If you want to access the deep web , you require to use special
software, such as Tor (The Onion Router).
Tor is a free open source browser software which uses onion
routing process.
This browser provides you very secure place. Since this software
creates encrypt environment for you, means no one can access your
data and not able to see it.
In order to use most of the sites on deep web, you must be able to
access and browse .onion sites on the Tor network.

7. The Onion Router
Tor is software that installs into your browser and sets up the specific
connections you need to access Deep Web websites.
Critically it is free software for enabling online anonymity and censorship
resistance.
Onion routing refers to the process of removing encryption layers from
Internet communications, similar to peeling back the layers of an onion.
Using Tor makes it more difficult to trace Internet activity , including “visits
to websites online posts, and other communication forms”, back to user.
It is intended to protect the personal privacy of users, as well as their
freedom and ability to conduct confidential business by keeping their Internet
activities from being monitored.
Instead of seeing domains that end in .com or .org, these hidden sites end in
.onion

8. How Tor works?

9. Examples:
The most infamous of these .onion sites was the now-
defunct Silk Road, an online marketplace where users
can buy drugs, guns and all sorts of other illegal items.
The FBI arrested Ross William Ulbricht who used to run
Silk Road website under the name “Dread Pirate
Roberts”.

12. Future
 The lines between search engine content and deep web have
begun to blur, as search services start to provide access to
part or all of once-restricted content.
 An increasing amount of deep web content is opening up to
free search as publishers and libraries make agreements with
large search engine.
 In the future, deep web content may be defined less by
opportunity for search than by access fees or other types of
authentication.

13. Conclusion
 Despite the vast amount of information the Deep Web contains,
it is still an ambiguous part of the digital world.
 Many internet users have not heard of it and believe that what
they see on their Google search results is all that the Web has
to offer.
 Other would rather have it abolished, claiming that it is an
underground world of crime and unethical behavior.
