The techniques of tracking users through their web browsers have greatly
evolved since the birth of the World Wide Web, posing an increasingly
significant privacy risk. An important branch of these methods, called
fingerprinting, is getting more and more attention, because it does
not rely on client-side information storage, in contrast to cookie-like
techniques. In this paper, we propose a new, browser-independent
fingerprinting method. We have tested it on a data set of almost
a thousand records, collected through a publicly accessible test
website. We have shown that a part of the IP address, the availability
of a specific font set, the time zone, and the screen resolution
are enough to uniquely identify most users of the five most popular
web browsers, and that user agent strings are fairly effective but
fragile identifiers of a browser instance.
