In the age of online photo-sharing, many of us have learned to censor photos which cast us in a bad light or reveal too much personal information. But while you might blur your driver’s license, have you remembered to blur your keys?
It shouldn’t be that surprising, but photos of keys can be used to make copies. And not just your photos, they could take a picture of your keys if you leave them sitting in plain view.
At this point, the software isn’t commercially available (how many people have a legitimate use for this stuff?), but someone with a good eye or who’s good at programming may take up the idea. So choose to be on the safe side and think twice before posting photos including your keys (apparently they found a number of people had put “what’s in my purse/bag” photos on Flickr) or leaving them lying around.
