> Schneier's blog tips an article about research into geolocation that can

> target's possible location to a radius of around 200 kilometers. Wang and
> colleagues then send data packets to the known Google Maps landmark servers
> in this large area to find which routers they pass through. When a landmark
> machine and the target computer have shared a router, the researchers can
> compare how long a packet takes to reach each machine from the router;
> converted into an estimate of distance, this time difference narrows the
> search down further. 'We shrink the size of the area where the target
> potentially is,' explains Wang. Finally, they repeat the landmark search at
> this more fine-grained level: comparing delay times once more, they establish
> which landmark server is closest to the target."
