Have Ever You Seen

THE ICEBERG

How Big ....

• The Deep Web contains 7,900 terabytes of information, compared to 19 terabytes of information in the Surface Web.
• 550 billion documents
• 500X surface web
• Google has identified 1.2 billion documents
• An Internet search typically searches .03% (1/3000) of available content.

Deep Web

• Not Discoverable
• Not Visible, Not Traceable
• Anonymously
• Darknet Content  (TOR)
• Cannot Be Indexed

Surface Web

• Visible
• Indexed by conventional search engines
• Also called clearnet, visible web, indexed web

Search Engines

1st we need to knwo how

works

• Spider (crawler) will seek out webpage by going from one hyperlink to another and adding each page to it's catalog

• A program called an indexer then reads these webpages and creates an index, storing the URL and important content of webpage.

• Each search engine has its own ranking algorithm that returns results based on their relevance to the user’s specified keywords or phrases.

Search Engine

Why not Searchable

• Some sites are not linked by other pages

• Some sites require authentication before accessing the actual content (password-protected resources) 

• Difficult desing for indexer

• The use of language JavaScript (like Ajax) misunderstood by spiders

• Dynamic links (URL)

• Darknet content

Darknet

• Computer network just like Internet
• Encrypted connection
• Accessed with specific software, configurations, or authorization
• Using non-standard communications protocols

• Researchers at the U.S. Naval Research Laboratory  Originally designed Darknet  to protect the identity of American operatives and dissidents in repressive countries like China
  • Freenet (1999)
  • GNUnet (2001)
  • I2P (2003)
  • TOR (2004) – most popular technology

Darknet (cont.)

TOR (The Onion Router)

• Tor is a free software for for enabling anonymous communication.

• Protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world

• Works on The Onion Routing technique

• .onion Links

• Access by Tor Browser

Onion Routing

• Onion routing encrypts and decrypts data typically 3 or more separate times, once for each tor node it passes through on the way to the destination via the path given by the tor directory server.

• It does this using the public key of the router(tor relay), which only the router’s private key can decrypt.

• No single router knows the entire network path from source to destination.

The Dark Side of The Moon

Deep Web

Ease of use: Surfing is more complex due the absence of indexing of the content

Speed: Slower to access than surface Web information.

Cybercrime: Inability to track down criminals. Activities range from the sales of illegal drugs and weapons, to hacking services, the hiring of contract killers etc...

Deep

Web

The Bright Side

"there is always something positive..."

Privacy and Security: Cannot know which connection is initiated as a user and which as node, making impossible the monitoring of the communications

Information: Access to private content and information (Government Security Info)

Freedom of speech and information: A way for people living under oppressive or restrictive regimes to reveal the truth like WikiLeaks
