Lehigh University and Washington University (St. Louis) researchers Yin Zi Chao, Song Li, and Eric Williams have developed a way to accurately track Internet users even when they change computers and browsers.
The new IT technology will certainly interest the advertising business, allowing them to "overtake" users with their ads, even if they decide to "run away" to another browser, for example, from Chrome to Firefox.
The technology reliably identifies the user's "digital fingerprint" in the form of installed extensions, plugins, time zones and even the presence of Adblocker. In a test with 1903 users, the method was almost 100% effective.
However, at the same time, the negative side of the development is noted, which is expressed in an open violation of confidentiality. In fact, a person has nowhere to go from imposed advertising.
Experts point out that this method can be used as part of multi-factor user authentication across browsers. For example, banks could better understand how legitimately a person is logged into an account.
