It is widely known that cookies can be used to track users. However, even privacy-aware users are trackable by the properties the browser sends with every request. Based on information like the browser vendor, plug-in versions and the installed fonts, a fingerprint may be created that uniquely identifies a browser. In this paper, the authors describe which properties browsers send to a server, allowing a unique fingerprint of these browsers to be created. With their data set of 1,124 visitors, they have already achieved entropy of 8.47 bits and 95.9% of the visitors were immediately identified as being unique.
