[Noisebridge-discuss] google war driving

[Joel Jaeggli]

how do you think wifi based location databases are populated?

they're not the only ones with a dataset like that, it's how you ipod
touch can localize itself to a few hundred meters.

there's some entertainment value to be had in moving an access-point
several thousand miles and having your location be off, but more to the
point mac addresses can be changed, it would be simple to randomize them
if one was so inclined.

see skyhook for example...

http://en.wikipedia.org/wiki/Skyhook_Wireless

for another of these.

I a little perplexed about the notion that wireless spectrum emissions
that leave your premises might be a deep privacy concern... as far as
the content is concerned that's what encryption is for, it's this sort
of thing that results in silly laws like it being unlawful to monitor
the 850mhz band.
