A method for tracking users across the Internet called “canvas fingerprinting” is simple to stop, but average Internet users may not know how to do it.
A research paper concluded that code used for canvas fingerprinting had been in use earlier this year on 5,000 or so popular websites, unknown to most. Most but not all the sites observed used a content-sharing widget from the company AddThis.
The researchers, from KU Lueven in Belgium and Princeton University, described how companies are looking for new ways to track users in order to deliver targeted advertising and move away from cookies, which can be easily deleted or blocked.
