Deep web
- 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.
- 5. Levels of the Internet and to which belongs the Deep Web 1. Surface Web 2. Bergie Web 3. Deep Web 4. Charter Web 5. Mariana’s Web
- 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
- 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”. Website: silkroad6ownowfk.onion
- 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.
