Concept :

Internet consists of three layers:

• The first layer is public(Surface Web ), consisting of sites that one uses frequently such as Facebook, Twitter, Amazon and LinkedIn. This layer makes up only 4% of the entire internet.
• The second layer, the deep web, is a network where data is stored in inaccessible databases (i.e. cannot be accessed through traditional search engines like Google). It is used to provide access to a specific group of people.
• The data is generally sensitive and private (government private data, bank data, cloud data etc), so kept out of reach.
• The third layer is the darknet which is also known as a part of the ‘Deep Web’. It is a network built over the internet which is encrypted.
• It is basically a layer of the Internet accessible only by using special software like Tor (The Onion Router), or I2P, which stands for Invisible Internet Project.
• Anything present on the dark web will not be pulled up in internet searches, thereby offering a high degree of anonymity.

Additional Information:

• The Kerala Police has set up a ‘state-of-the-art lab’ to intervene and crack down on the rising criminal activities over the Darknet, also known as the underworld of the Internet.
• Spearheading the programme is Cyberdome, the State police department’s premier facility dedicated to prevent cybercrime and mitigate security threats to the State’s critical information infrastructure.
