Here's a link to the article published by my University: http://www1.lehigh.edu/news/novel-technique-tracks-more-web-users-across-browsers
And here's the paper itself: http://yinzhicao.org/TrackingFree/crossbrowsertracking_NDSS17.pdf
Basically it's a technique that utilizes hardware and OS recognition to more accurately track and fingerprint users. Seems hyper-invasive to me.
From the paper itself.
"Abstract—In this paper, we propose a browser fingerprinting
technique that can track users not only within a single browser
but also across different browsers on the same machine. Specifically,
our approach utilizes many novel OS and hardware level
features, such as those from graphics cards, CPU, and installed
writing scripts. We extract these features by asking browsers
to perform tasks that rely on corresponding OS and hardware
functionalities.
Our evaluation shows that our approach can successfully
identify 99.24% of users as opposed to 90.84% for state of the
art on single-browser fingerprinting against the same dataset.
Further, our approach can achieve higher uniqueness rate than
the only cross-browser approach in the literature with similar
stability."
