Online Security From… Graphics Cards?



The researchers from the “Physically unclonable functions found in standard PC components” (PUFFIN) project say that seemingly identical graphics processors commonly used for gaming actually contain unique “fingerprints” that allows them to be differentiated from each other. Known as a physical unclonable function (PUF), these minute and uncontrollable manufacturing differences can be detected by software, allowing a particular graphics card to be linked to a specific user account.
