Researchers have demonstrated a new type of fingerprinting technique that exploits a machine's graphics processing unit (GPU) as a means to track users across the web persistently.

Dubbed DrawnApart, the method "identifies a device from the unique properties of its GPU stack," researchers from Australia, France, and Israel said in a new paper," adding " variations in speed among the multiple execution units that comprise a GPU can serve as a reliable and robust device signature, which can be collected using unprivileged JavaScript."
