Researchers have created a new browser/web tracker. It is able to track you trough several browsers on the same system. And it does this with a very high succession rate.
It works by tracking properties of the operating system and hardware (like GPU and CPU). It is able to detect a user successfully in 99.24% of the cases. That is even better then a traditional tracker (single browser, cookies, user-agent etc.) 90,84%
The first generation webtrackers used only cookies. Later on the tracker used detection of installed plug-ins and user-agent properties. But because users do use more then one browser they miss out on some of your data. So they came up with this. In my eyes a new way to invade my system and my privacy.
In the paper it is clear that they use javascript for tracking. So well blocking that helps. But it will break a lot of websites.
Still the Tor browser is able to block most of the tracking. Only some info about soundcard and screen resolution is gathered then.
