The Deep Web is the part of the Internet that is beyond the tracking of search engines and allows anonymity of users
The Deep Web, or deep web, is not part of internet Internet is part of the surface, or rather, which is invisible to the search engines because the content is not indexed it. But what does this mean content not indexed? Since it refers to all content that is inaccessible from conventional Internet search engines for different reasons, like treating pages and websites password-protected documents unrecognizable or content formats that require interrogate its database to access information.
The term Deep Web may evoke a misconception of what it really is, for the automation of our brain associated with illegal deep. Nothing is further from reality, into the Deep Web illegal activities has been much development, but this sector is better known as “darknet” and to access it is necessary to use a proxy. Likewise, the Deep Web is also used as the “holy grail” of anonymity in communications, to be very hard to trace users. Therefore, it is also useful to prevent control of the information that they want to make public; for example, it is the method used by political dissidents from repressive regimes to communicate with the outside.
How the phenomenon arises Deep Web
The Deep Web has always existed, in fact, accounts for an estimated 90% of total Internet content. This does not mean that 90% is dedicated to illegal topics, only that it is inaccessible to spiders crawling search engines. Deep Web uses a range of tools aimed anonymity, the most famous being The Onion Router (TOR) a platform created by the US Naval Laboratory, which allows hide IP address and other data related to the user’s identity, and it works using different levels like the layers of an onion encoding.
Other access platforms the Deep Web are I2P (Invisble Internet Project) and Freenet, which along with TOR give the option to navigate using a ‘pseudo-domain “. These platforms use complex routing codes that protect the user traffic analysis, being the main inspiration anonymity thereof. For all this, the size of the Deep Web is constantly growing, and the leader in information security company Trend Micro, has made a thorough study of traffic in the Deep Web, entitled “Bellow the Surface: Exploring the Deep Web” in which they offer very interesting phenomenon Deep Web information. Robert McArdle, “Senior Research Manager” Trend Micro said that “Due to the nature of the Web Deep, it is incredibly difficult to give a reading on the volume of sites in a given time, but we were able to collect about 576,000 URL in just over two years. “
Illegal activities in the Deep Web
How could it be otherwise, the possibility of anonymity is too juicy for criminals. Thus, in the “darknet” there is a whole market of illegal goods, and offer criminal disservice. As reported by Trend Micro in addition to drug trafficking, market star “darknet” Deep Web users can easily access services like Bitcoin money laundering, stolen accounts to sell, selling illegal passports, leaks government services hired murderers and above containing child pornography.
