Before you tweet a photo of your delicious home-made dish, check your settings — your phone might be embedding coordinates in your photos, leaving your location open to prying eyes.
Using the built-in GPS, phone camera applications can embed the latitude and longitude of a location in photos. Coordinates aren't shown in your photo library, but if you post a geotagged pic online, someone with an evil motive can easily extract the photo's EXIF data and find out where you live, eat or hang out.
Creepy, right? This is a big security risk, especially for parents who post photos of their children online. So if you want to disable geotagging on your Android, iPhone or BlackBerry phone, this how-to will help.
