"Until now, the idea that your smartphone's camera could be used to secretly build a 3D model of your home or office, upload teh data to a remote server, and allow them to virtually snoop around your home, was the preserve of works of science fiction and fantasy.
However researchers at the School of Informatics and Computing at Indiana University have shown that this is, in fact, a reality, and have created a simple camera app for the Android platform which criminals could use to remotely burgle your home or office."
