Almost all smartphones and GPS cameras, by default, enable the geotagging feature. This new technology gives the public control to see where a posted picture was taken, within fifteen feet. A stalker could simply right click the photo you tweeted of your kids playing at home, click an option similar to ‘view image data’, and in an instant, find out where you live by having access to the longitude and latitude measures of your home. There are even sites that help you translate smartphone posted pics into addresses and maps. icanstalku.com has a how-to on how to disable geotagging on your smartphone.
