"[Tadayoshi] Kohno appears to be aware of the interest from surveillance groups that his techniques could generate, saying in his paper: 'One could also use our techniques to help track laptops as they move, perhaps as part of a Carnivore-like project.' Carnivore was Internet surveillance software built by the Federal Bureau of Investigation."

The UCal doctoral candidate says his method works without any cooperation by the targeted machine and in spite of large distances between the target computer and the one attempting to identify it. As the Bard of Avon said, "Oh brave new world, that has such people in't."
