Under the net all day we navigate, there is a giant spiderweb bigger than we can imagine unseen webs: the Deep Web.
Recently, terms such as proxy, anonymous surfing, VPN, Tor, etc., Have begun to emerge in the conversations of ordinary people more often than normal. Usually, and most of the lifetime of the Internet, the great bulk of network users never worried about these things.
The average user simply open your browser, search Google and check your social networks. But in view of all that has come to light in recent years, the government and spyware PRISM, companies that provide services to almost all use dedicated to collect our data and sell to the highest bidder, censorship around the world and blocking access to information to citizens in countries with political crises situations, people increasingly soaks more than the knowledge necessary to protect your identity, skip censorship and discover the other layers of the web.
DEEP WEB, THE OTHER INTERNET
Although it may be hard to believe, to the point that for many it is an urban legend, the Deep Web or deep Internet (Deepnet, Hidden web, web Invisible) include the vast majority of Internet. The Deep Web is the content of the World Wide Web that is not part of the Web Surface, ie not part of sites that can be indexed by search engines and that any user can access from a current browser.
While few studies, one of the most recent done by the University of California estimated that the Deep Web consists of about 7.5 petabytes (one petabyte is 1000 terabytes). According to similar studies, the web that we all know (Facebook, Wikipedia, blogs, etc..) Consists of less than 1% of all Internet.
The concept is simple yet confusing, but comparisons of the web are made with the sea. On the surface of the sea are the search engines, which list the sites that have links between them, static pages such as this blog. That is the area of the ocean that we can "surf". Deeper are databases. When asked a question to a database, it generates a single page that is not indexed in the search engines and therefore not part of the Surface Web.
Academic publications such as private journals, are not part of the surface, as they are hidden in individual pages within private networks, such as those downloaded the deceased and Aaron Swartz for which he was jailed and prosecuted. Many are well hidden because they are part of an Intranet, usually corporations or universities.
TOR
Further below, in the depths of the sea, lies the Tor network, darkest part of the network. This consists of a series of secret web sites whose addresses end in. Onion, and require specialized software to access. This software is known as Tor. Many people use it for anonymous access to your network, and encrypts the content passing through it.
Tor is a network of virtual tunnels that protects user communications by bouncing inside a huge network maintained by volunteers around the world, was originally designed as a project routing Naval Research Laboratory of the United States in order to protect government communications.
The Deep Web is not a toy, and the darkness that surrounds it has made it the niche where the worst possible things: sales of illicit drugs, pornography, weapons, and even murderers for hire. It is said that the Deep Web do not surf, diving. You do not have engines, but some reference sites to start your search as the Hidden Wiki, and you must be very careful what you are looking for, then you may find something you do not want to see or something that others do not want you to see.
