System fingerprint: a passive, cross-browser user tracking that works even in private mode “Web browsing software needs to share system information with the visited web services. However, shared information can characterize the user’s system, and therefore allow individual identification, even in private browsing mode or after deleting HTTP and Flash cookies. In our tests, even a Firefox-based anonymous web browser could be tracked with the same identifier that was assigned to other browsers of the same system.
If you would like to test this tracking feature of your browser, just click on the link below! After the analysis, the test computes an identifier for your system, which we call the system fingerprint. If you like, you can compare these IDs in different browsers, and even in private browsing mode. Naturally, it is not the purpose of our test to facilitate user tracking but to show the weak points of privacy protecting systems.” http://pet-portal.eu/?page=fingerprint&intl
