The group – Yinzhi Cao and Song Li of from Lehigh University in Pennsylvania, and Erik Wijmans from Washington University in St. Louis – have worked out how to access various operating system and hardware-level features that can fingerprint an individual machine, regardless of browser.

These include screen resolution with zoom; CPU virtual cores; installed fonts and writing scripts; the AudioContext call; GPU features such as line and curve rendering, anti-aliasing, shading, and transparency; and more.

The researchers reckon they can fingerprint a machine with 99.24 per cent accuracy (compared to under 91 per cent for browser fingerprinting).

Cao and friends say there’s one browser that defeats the worst of their attacks: the Tor browser.
