Location-data privacy

We've talked a lot about cell phone tracking and anonymized and de-anonymized data

If you know where someone works and you know where someone lives, you can figure out who that person is.

could this be the thing that gets Congress to get off their asses and make some actual privacy legislation?

sold geolocation information that could be used to reveal visits to sensitive locations

timestamped latitude and longitude locations

They just happened to sleep at a certain place every night

they can now track it with other databases and put it all together

law enforcement gets around having to get a warrant by purchasing it

50 billion location pings from 12 million Americans

really precise longitudinal geolocation information is absolutely impossible to anonymize

if someone knows where you live and they know where you work, they can track your every move

Stores are watching you, too.

critics maintain that location data is easy to re-identify

when you've de-identified data that you can't actually get it back

I'm a little freaked out about the privacy considerations.

Somebody could hack into this ... easily figure out where I live.

I actually can't find out the truth about that.

turn off geolocation on Facebook, Twitter

don't talk about your vacation until you get back

make sure that if they're posting online, that there's no geolocation
