Invisible Web, as the name suggests is the invisible part of the World Wide Web which either is not indexed on the search engine or is subjected to various access restrictions. The regular search engines cannot trace or track the content uploaded on the Invisible web which means not everyone can get access to it. Just in case you aren’t aware, the World Wide Web can be called the metaphor Ocean which further has different sections like Surface Web, Shallow Web, Deep Web, and Dark Web.
- Surface Web includes the normal part of the Web which we browse and it includes the set of websites indexed by the automated search engines. Search engines can index and track all the content uploaded on the Surface Web and thus it is available for everyone. All the social networking websites, online shopping, etc comes under Surface Web.
- Shallow Web is basically used by the developers and other IT people which includes the databases stored by the developers, servers, programming language, etc. It is actually the background of the webpages you and I browse.
- Dark Web and Deep Web – These two are slightly different and combinedly make the term Invisible Web. All the information and content stored or uploaded on the Dark and Deep Web are hidden and are not accessible to everyone. The Deep Web includes personal content like online banking, email inboxes, cloud storage, etc which requires some kind of authorization to access.
Whereas the Dark Web actually refers to a set of anonymously hosted websites that are not indexed by the regular search engines. There are specific web browsers and search engines to access this Invisible Web and this is what we are going to learn in this post.
