Panopticlick

This web-based tool designed by the Electronic Frontier Foundation (EFF) tests your “browser fingerprint”, the information your browser is giving away that makes your device uniquely identifiable.

Many users think that by disabling cookies they can avoid being identified by websites, but companies have developed other strategies to identify individual computers. Data like screen size and color depth, time zones, cookies and the operating system running on your machine provide bits of identifying information. By using Panopticlick, you can see your browser fingerprint and understand how your information is transmitted to websites, uniquely identifying your digital device.
