Thomas’s case went something like this: Your browser (Chrome, Safari, whatever) has a ​very unique configuration, and it broadcasts all sorts of information that can be used to identify you as you click around the web. You’re basically leaving “footprints,” as Thomas calls them (others prefer “fingerprints”), all over the webpages you visit. Thus, it’s a matter of linking one footprint to another—an expert could spot the same prints on Facebook and NYTimes.com as on Pornhub and XVideos.
