[Geowanking] location privacy?

[Edward Mac Gillavry]

Just had a look at the slides Tom Coates <www.plasticbag.org> presented at 
ETCon earlier this year. There are a few notes on how UMS Conversations deal 
with location and privacy. You can always strip some decimals of the values 
that are given for lon/lat? A thread a few months ago discussed several 
notations for location that use some quadtree-like structure: another means 
to make the true location less obvious.

Dav Coleman notes at 
<http://www.danger-island.com/~dav/blogosphere/friendster2/>:
"People are lying about their locations. I know Sandwichgirl, and I know she 
doesn't live in Bosnia-Herzegovina, and even though she's a travel agent, I 
bet she's never even been to Bosnia-Herzegovina. And I have my doubts about 
Nathan in Madagascar."

Cheers,

Edward
