Someone who has sneaked into your circle of virtual friends somehow, might know the exact location of your house from the geotagged photos, and get to business while you are posting vacation pictures, says a Webroots employee. What is even more troubling is that sometimes people befriend complete strangers online, or use location-based services to meet them.
Turning off all applications that monitor your whereabouts, on the other hand, might require some fiddling, especially if you have checked something in a hurry while installing an app, or while setting up your phone for first use. Webroots thinks it will take at least a year for people to learn how to manage their location-based apps, the way it took a year for Facebook users to realize its privacy implications.
