Transcript of Analysis and Methods of Accessing The Deep Web

Analysis and Methods of Accessing the Deep Web The Internet The internet is segmented into two parts. The Surface Web and the Deep Web. The Surface Web The Surface Web is that portion of the World Wide Web that is facilitated and referenced by conventional search engines. The Internet is larger than you think. This presentation will provide an in depth look into the full spectrum of the Internet. Thesis Surface Web You The Metaphor The Deep Web The Search Engine The Deep Web Compared to The Deep Web the Surface Web is just a miniscule portion of the entirety of the World Wide Web. It is that portion of the Web that cannot be crawled by traditional search engines. http://upload.wikimedia.org/wikipedia/commons/d/d2/Internet_map_1024.jpg http://searchengine-results.net/wp-content/uploads/2012/01/Search-Engines.png Introduction http://curiousanimals.net/wp-content/uploads/2008/06/two-parts.jpg Visualization of data paths on the Internet Visualization of the Surface Web The General Preconceptions of the Internet All information on the Internet can be accessed at the touch of a key with search engines such as Google. How much of the Web can you actually search through Google? This preconception is false This raises a question. Answer: A sliver of the Internet Yum But why? Like everything else the Deep Web has a dark side Contents Of The Deep Web! Deep Web Facts Pages formed dynamically, as a result of the queries submitted by the search engines.

Unlinked web pages that are prevented by the web crawlers from accessing the content.

Private Web: sites that require registration and login (password-protected resources).

Files hosted by File Transfer Protocol (FTP) that are not indexed by most search engines. Anything you can search on a search engine Majority of the Information Can be as useful or harmless. Whats on the dark side of the Deep Web? Drug Dealers
Human Sex Traffickers
Sexual Deviants
Professional Criminals
Political Revolutionaries
Mentally Disturbed
Underground Fights Rings
Drug Cartel Executions
Terrorist Networks Renegade Scientist
Religious Extremist
Government Agents
Professional Hackers
Money Launderers
Thieves Conclusion The Deep Web is what you make of it. It is filled with the bizzare, disturbing, illegal and everything inbetween. I believe knowledge should never be viewed through a narrow looking glass, but viewed as a whole so YOU can decide what you want to believe and what you don't.

**I am in no way responsible for anything you do.** More About Dynamic Web Pages What happens when you search the Internet When we browse the Internet we typically use search engines to facilitate and sort websites and information from a pre-organized index which can be referenced in a fraction of a second. This is translated into a easy to use form in which we get the information that we want. Until today a majority of you were not even aware of the existence of content on the World Wide Web besides the Surface Web. By: Barkha Dhamechai

tor uses relays
what is relay how it helps
tor map there The Onion Router (TOR) Network of virtual tunnels

Protect against "TRAFFIC ANALYSIS". Messages are encrypted repeatedly as layers of onion.

Not even the last routing node can read the message because of several encryptions What is a relay? Referred to as "routers" or "nodes"

Three types:
Middle Relays
Exit Relays
Bridges Complex urls difficult to remember.

.onion extensions. Government-released data (NASA, Library of Congress, etc.)

Private online communities (Anonymous, etc.)
