As photo-making devices become more and more location aware, many people unwittingly give up a lot of privacy by publishing location-tagged images online. If privacy is something you care about and you’d rather not broadcast location data along with your photography, a free Windows program called Geotag Security can help you scrub the geotag information from your pics. All you do is select a folder to scan, and the program will check the images within for location data and remove it.
