Your graphics card could be used to track you across the web regardless of cookie consent

Telling a website to stick its cookies someplace else might not be enough to keep it from tracking you across the web—there are other identifiers that can help down who you are and what you’re doing as you travel the silicon super narrowway. These techniques rely on tracking the exact configuration of hardware you’re running inside your PC, though researchers suggest this form of hardware tracking could be done with even greater accuracy through something known as GPU fingerprinting.

Outlined in a research paper [PDF warning] From co-first authors Tomer Laor of Ben-Gurion University and Naif Mehanna from University Lille, CNRS, and their respective teams (via Bleeping Computer), the technique nicknamed DrawnApart takes advantage of minor differences in a user’s GPU behavior to uniquely identify them across the web.
