Thousands of websites use HTML5 Canvas —a method supported by all major browsers that allow websites to dynamically draw graphics on web pages—to track and potentially identify users across the websites by secretly fingerprinting their web browsers. Over three years ago, the concern surrounding browser fingerprinting was highlighted by computer security experts from Princeton University and KU Leuven University in Belgium.
