Does your web browser have a unique fingerprint? If so your web browser could be tracked across websites without techniques such as tracking cookies. Additionally the anonymisation aspects of services such as Tor or VPNs could be negated if websites you visit track you using your browser fingerprint. This service is designed to test how unique your web browser's fingerprint is, and hence how identifiable your browser is.
Browserprint is a free open source project designed to provide the same and better functionality as the original Panopticlick. Several of the tests are based on publicly available code from Am I unique? and Fingerprintjs2. The inspiration for each test can be found on the sources page.
Browserprint is developed by a student of and generously hosted by the University of Adelaide. Browerprint's development was partially funded by ACEMS. This project would not be possible without these institutions' help.
News 2017-02-15 Browserprint now tries to guess what operating system you're using in the same way that it guesses your browser. This can also theoretically be used to detect and defeat fingerprint spoofing.
News 2017-02-13 Browserprint now tries to guess what family of browser you're using (e.g. Firefox, Chrome, ...) by running part of your fingerprint (not including user-agent, that's cheating) through a machine learning algorithm. Theoretically this can be used to detect and defeat fingerprint spoofing.
