If you feel “Big Brother” is watching what you do on your computer you may not be too far off. There are very creative ways to track your online activity. Computer expert Thor Schrock is the owner of Schrock innovations in Omaha and says it happens every time you click on a website.
Schrock says, “It is called canvas fingerprinting. When you go to a website all kind of pictures come to your computer on the browser. Every computer handles pictures a bit differently and that unique way can be detected and used as a fingerprint to identify that computer.” Schrock says it can’t tell who owns the computer but it does keep track of what the user likes – for example radio programs or plants. That information can be used to push the marketing of those items to the user.
Schrock says this kind of tracking isn’t overly dangerous but if you combine it what a number of other tracking methods, like what Google is doing, they can develop a precise profile about you as an individual tied to your identity.
The good news is there are ways to block this type of tracking.
