Since the Silk Road bust, the Deep Web has been cast as some nefarious digital wasteland where basement-dwellers go to buy drugs, hire hitmen, and exchange kiddie porn. And sure, that’s not entirely untrue, but there’s plenty more to it than what made headlines.
In fact, if you’ve ever checked your bank account online or composed a message in Gmail, you’ve been on the Deep Web.
If you think of the Internet as we know it, or the “surface web” -- Google, Wikipedia, this website, and most others you visit every day -- as the Milky Way galaxy, the Deep Web is what makes up the rest of the Internet universe. What's in it? Academic databases, government records, personnel files, internal corporate networks, and your own private accounts protected by a log-in (e.g., your bank account). Plus, a huge chunk of unique URLs containing complex scientific data collected by the likes of NASA that would be indecipherable by you or I.
