This makes Facebook the first major web company to offer a platform on the dark web. So, what is the dark web and why did Facebook join it? First off, it’s important to understand that the internet is vast and constantly growing, and the majority of our daily usage only scratches the surface. Google, Yahoo, and other search engines only show about 4% of the data available on the internet. To access the other 96% requires customized digging through individual sites, subpages, restricted access journals or archives, and so on. This 96% is called the “deep web.” It’s also important to understand that pretty much everything we do online is visible, traceable, and possibly being monitored. Everything except... for the areas of the deep web that are masked by the “dark web.” The “dark web” is concealed through a series of identity masking layers, which basically means that you can access and interact with it anonymously without being tracked. This is achieved through special encryption software like TOR, an acronym for The Onion Router, which when installed on your computer, appears and acts like your standard Firefox browser, albeit slower. But instead of routing your connection through a direct line, TOR routes everything through a series of encrypted computers all over the world, bouncing around randomly before it reaches its host destination. This makes the origin of the data and the people searching for it, unknowable. So while you might actually be in New York, your search traffic can appear to be coming from random points all over the world, making your location essentially untraceable. So why does Facebook, a company that is anything but anonymous or discreet, want this? Well, they claim that it’s all part of a long term effort to achieve greater “accessibility and security” for its users - which according to some critics, is pretty much just code for desired global domination. Facebook wants to be used by everyone, everywhere. And pushing the site into the dark web opens Facebook up to users who might otherwise be unable to access it, or might worry about government surveillance or other security controls or threats. Places like Iran or China, for example, are known to restrict access to social sites, like facebook. TOR won’t shield users’ Facebook profiles or activities -- those will still be public -- but it will keep their location and potentially their real identity, hidden from the authorities.
