Pictures Julie Matheny emails or uploads from her smartphone could be revealing exactly where she's taking the photos.

"You know it's a little scary. There's creepy people out there. You never know who's watching your kid."

And it's possible to watch from a safe distance --- just by tracking the locations--- where photos are taken.

"Most people are unaware."

Willam Ambruzs works at a company called Flashback Data, and shows how to find the location information that's automatically mapped on smartphone photos. The GPS data includes longitude, latitude, even the elevation. Just map the coordinates and then it's easy to zoom in on where you are and when.

"They're also time stamped when i'm at those locations and when i'm not," says

And the tracking gets scarily specific. "In a house that could be a bedroom. On a street that could be a particular address on that street."

To protect your privacy all you need to do is deactivate your camera's geotagging. "You'd select settings. You'd scroll down to privacy. Once you're in privacy you're going to look for location services. You want to go to camera. And as you can see my camera is turned on. Just simply take that slider and turn it to off."

That's what this mom did.

"At least I know they can't find my house. They can't find my kids' bedroom," says Matheny.

Peace of mind, as smartphones keep offering more opportunities to map your every movement.
