Browser Fingerprinting

As technology has advanced, it has become easier to differentiate between users just based on the given instance of the browser they are using. Each browser keeps some information about the elements it encounters on a given webpage. For instance, a browser will keep information on a text font so that the next time that font is encountered on a webpage, the information can be reproduced more easily. Because each of these saved elements have been accessed at different times and in different orders, each instance of a browser is to some extent unique. Tracking users using this kind of technology continues to become more prevalent.
