Computer Warming a Privacy Risk

A security researcher has a devised a novel attack on online anonymity systems in which he literally takes a computer's temperature over the internet.

The attack uses a phenomenon called "clock skew" the tendency for the precise clocks in modern computers to drift off of the correct time at slightly different rates, which can be affected by heat.

"When a crystal is manufactured, it has a clock skew, and it's different for each crystal (throughout its) lifetime," explains Steven J. Murdoch, a Cambridge University researcher who discussed his work at the Chaos Communications Congress on Thursday. Wired News: Computer Warming a Privacy Risk
