FingerprintSwitcher.
Modern methods of user identification can identify him only by a set of browser properties. Let's say that among a million users, tens of thousands can have a certain resolution, but only a few thousand have a certain resolution and a certain set of plug-ins. A set of such properties forms browser fingerprint. By adding new factors, the site can determine exactly what user visits it, even if he uses proxy. This problem can be solved with FingerprintSwitcher service, since it provides a new set of properties each time. In fact, FingerprintSwitcher can be called a proxy service analog for fingerprints.
