Flickr has just announced a new privacy feature for geotagged photos, called Geofences. Over 300 million photos and videos have been geotagged by Flickr members so far, and the engineers wanted to make managing privacy of these geotagged shots easier for the community. Instances in which you might want to conceal your photo’s location include: shots taken at home or at the private residence of someone else whose exact location you don’t feel comfortable broadcasting to the world at large. According to one Flickr engineer, who helped develop the new feature, “Geofences are special locations that deserve their own geo privacy settings. Simply draw a circle on a map, choose a geo privacy setting for that area, and you’re done. Existing photos in that location are updated with your new setting, and any time you geotag a photo in that area, it gets that setting too.” This saves the photographer the hassle of tweaking default geo settings every time she uploads media taken in a location she has deemed private.
