And with plug-ins that can extract geotag data from pictures, even people keeping blogs or personal pages are not safe. They say that anyone with a modicum of programming knowledge can write a program that could search for the combination of geotagged pictures and “On vacation” statuses. Security experts are particularly worried about the pictures posted on social networks, since they are usually accompanied by real-time statuses. But, of course, if the user chooses to share it, he can.Īlso, some other sites – and Facebook is one of them – sometimes format the uploaded pictures in such a way as to make it impossible to fish out geotag data, but that is purely accidental.

To people concerned by the possible risk tied to geotagging, The New York Times recommends visiting, a website that provides simple, step-by-step instructions on how to disable the option on various mobile devices.īut even as the awareness of the risk is rising among the lowly users, online services such as Flickr have recently made the geotag data of pictures posted via mobile devices unavailable by default to anyone except the photographer.

The picture also contained a geotag – metadata that reveals the exact latitude and longitude of the spot on which the picture was taken – which ultimately revealed to anyone who might be interested where his house was located.Ĭombining this information with the Twitter status saying “Now it’s off to work,” he has given potential thieves the perfect opportunity to burglarize his home. Here’s an example: “MythBusters” host Adam Savage took a picture of his car parked in front of his house, and posted the picture on Twitter. The ubiquitous automatic geotagging of pictures taken with smartphones and digital cameras and then posted on the Internet could prove to be a real security risk.
