Photographic key duplication
[Ben] and his associates over at the University of California at San Diego came up with a way to duplicate keys using a picture of them. They developed an algorithm that uses measurements from known key blanks to extrapolate the bitting code. Because the software is measuring multiple points it can correct the perspective of the photo when the key is not photographed on a flat surface, but from an angle.
They went so far as to test with cell phone cameras and using a telephoto lens from 195 feet away. In most cases, correct keys were produced within four guesses. http://hackaday.com/2009/09/22/photo...y-duplication/ |
