Mobile Sensor Networks

Quote from 4th thread: @ravonn

Regarding the anonymity I suggested using Geohash with user configurable precision. The system would weight a user's data down if the user chooses a more coarse location since the data now spans over a larger area. They would still contribute, only less so.

I think it would be easy on the server and easily queried in the databases. The servers could also use the exact same mechanisms when visually displaying data on maps, for example. If you zoom out you decrease the precision (that is, increase the area of the Geohash grid cells) so it would automatically weigh user data down. In the grand scheme of things, those who already had low weights would now participate with "normal" weight. If that makes any sense.
