How does it work? A web page that wants to fingerprint you invisibly writes a bit of text to your browser window. AddThis chose to go with “cwm fjordbank glyphs vext quiz” which uses every letter of the alphabet. Some other providers decided that simply typing the alphabet in order works just fine, too. The text is rendered with subtle variations on every computer (due to things like the fonts you have installed, your system clock, etc.), and in that respect it’s a lot like your actual fingerprints. The tracker then analyzes the output to identify you and serves up targeted ads.
