Today we're launching version 2.0 of our tracking and fingerprinting detection tool, Panopticlick. This version brings new tests to our existing tool, such as canvas and touch-capability fingerprinting, updating its ability to uniquely identify browsers with current techniques. In addition, we're adding a brand new suite of tests that detect how well your browser and extensions are protecting you from (1) tracking by ads; (2) from tracking by invisible beacons; and also (3) whether they encourage compliance with the Do Not Track policy, which EFF and a coalition of allies launched earlier this year. We've also redesigned the site look and feel, including friendlier layout on mobile devices. If your browser lacks protections, Panopticlick 2.0 will recommend installing tools that are available on your platform, such as Privacy Badger, Disconnect or AdBlock, in order to get better protections as you navigate the Web.
Our new tracker- and ad-blocker detection tool gives results for how well your browser is protecting you in three categories. Firstly, it lets you know if you're protected from invisible trackers that are included on many sites without users being aware of them. Secondly, whether you're protected from ads that track you across different domains. And thirdly, it tests if ad companies that promise not to track users by complying with our Do Not Track policy are unblocked by the browser, which gives these companies the incentive to do the right thing. We test the effectiveness of your protection by creating a number of domains that mimic real trackers, observing if resources on these domains are loaded or not. When the test is finishes, we present the users with a simple, informative table indicating their level of protection, with helpful suggestions when their protection isn't adequate.
Finally, we've completely rewritten the back-end code in Python and open sourced the project so that you can see how it works yourself!
