The web has become an essential part of the authors' society and is currently the main medium of information delivery. Billions of users browse the web on a daily basis, and there are single websites that have reached over one billion user accounts. In this environment, the ability to track users and their online habits can be very lucrative for advertising companies, yet very intrusive for the privacy of users. In this paper, they examine how web-based device fingerprinting currently works on the internet. By analyzing the code of three popular browser-fingerprinting code providers, they reveal the techniques that allow websites to track users without the need of client-side identifiers.
