This seminar presentation provides an overview of deep web data extraction. It defines the deep web as content that is not indexed by typical search engines. The presentation covers the history of the deep web, how search engines work, differences between the deep web and surface web, how to access the deep web using tools like Tor, advantages and disadvantages of the deep web, and future applications. The presentation concludes that the deep web provides anonymous access to valuable information not easily accessible otherwise and will continue growing as more users seek online privacy and security.

5. History of Deep Web
 Jill Ellsworth used the term invisible Web in 1994 to refer to website were not registered with any
search engine
 The initial definition of deep web suggest that “surface Web content is persistent on static pages
discoverable by search engine through crawling”
 The Deep Web came into the eye if the Government or so called the authorities ion 2013 when the
silk route
 From that time the Government shows a great interest on deep web. Constantly keeping an eye on
the deep network

6. How Search Engine Works

7. Deep web vs Surface web

8. Accessing the Deep Web

9. Cont…
There are some special kind of links available called
as the onion, with an .onion extension
Some of the .onions links are
http://v6pgrjno6mzbjicf.onion - The Onion Press
http://am4wuhz3zifexz5u.onion - The TOR Library
http://zbnnr7qzaxlk5tms.onion - WikiLeaks mirror
http://kpvz7ki2v5agwt35.onion - Hidden Wiki

10. Cont

11. Advantages and disadvantages
Well as per advantages comes in the deep web
provides access to sites that have not been indexed by
the search engines, including the database entries .
It contain a wealth of valuable information,
An easy way to get a valuablable research materials
that are not available or

12. Future Scope
 With the advancement and amount of information available on the deep web more
and more users are migrating in using deep web .
 More and more users wants to be more secure and anonymous while they are
online.
 To gain the valuable information that are not easily available by the surface web.

13. Conclusions
 We’re looking at the end of the internet, as we know it
 It’s growing into a two tier-internet. One being a toll highway
 And another being a slow freeway. But we can do something
about it. We can all go Deep Web.
 It’s not a place . It’s a state of mind , a way of being ; being
anonymous and safe
