What The Internet Knows About You

Most Internet users know that a website they visit can access various information about the computer system used to make the connection. This includes the screen resolution, operating system, IP address and web browser among other things. But those are not the only information that can be gathered when users visit a website.

What would you say if someone told you that they could find out additional information about you. Your Facebook or Twitter friends, websites that you have visited in the past including financial, government or adult ones, email accounts or even what you have searched for in the past in search engines.

The What The Internet Knows About You website will display those information and more on its website to all users who are connecting to it.

The method the website uses to retrieve and display those information is not a hack or exploit as it uses build in functionality in all modern web browsers to do that. It basically makes use of the feature to display visited links in a different color than not visited links.

All that needs to be done is to display those links (hidden to the user) on the website and check their link color to find out if a user has visited them. The method checks popular links against the user’s web browsing history to see if the page has been visited.

The What The Internet Knows About You website contains general link collections, e.g. the top 5000 or top 20000 websites in the world but also specialized checks for banks, social networking sites or government websites.

The service explains in detail how the information are retrieved and what users can do to protect their privacy so that these information cannot be retrieved.

  • Disabling your browser’s history
  • Disabling CSS styling of visited links
  • Using a special browser extension to fix the problem

    Are we allowed to know what they know about someone else than ourselves? :)

    Right now, page doesn’t load. Gee, I guess we’re a bunch to wonder what they know that we ignore!
