Not All Browsers Are Created Equal: Comparing Web Browser Fingerprintability
This work addresses privacy concerns for web users by showing that browser selection affects susceptibility to fingerprinting, though it is incremental in nature.
The study measured the fingerprintable attributes of various modern desktop and mobile browsers, revealing significant differences in their potential for user tracking, which impacts privacy based on browser choice.
Browsers and their users can be tracked even in the absence of a persistent IP address or cookie. Unique and hence identifying pieces of information, making up what is known as a fingerprint, can be collected from browsers by a visited website, e.g. using JavaScript. However, browsers vary in precisely what information they make available, and hence their fingerprintability may also vary. In this paper, we report on the results of experiments examining the fingerprintable attributes made available by a range of modern browsers. We tested the most widely used browsers for both desktop and mobile platforms. The results reveal significant differences between browsers in terms of their fingerprinting potential, meaning that the choice of browser has significant privacy implications.
