GPS cell phone safety

With the advent of smartphones, taking photos with a cell phone and sharing them to friends online has become common.

But what many people don't know is that a photo taken with a cell phone can contain GPS information that could potentially allow strangers to track locate where you are and where you've been.

Free software is available online to interpret GPS data and point out the exact location your photo was taken on a Google map.

Local hacker and computer security consultant Brad Haines tells Global viewers how to to turn off GPS settings on their cell phones so when you take a photo and post it online, it won't contain GPS data that could let strangers -- or stalkers -- track down where you are.
