http://www.sciencedaily.com/releases/2008/10/081029181606.htm ScienceDaily Oct. 31, 2008 UC San Diego computer scientists have built a software program that can perform key duplication without having the key. Instead, the computer scientists only need a photograph of the key. The bumps and valleys on your house or office keys represent a numeric code that completely describes how to open your particular lock. If a key doesn’t encode this precise “bitting code,” then it won’t open your door. “We built our key duplication software system to show people that their keys are not inherently secret,” said Stefan Savage, the computer science professor from UC San Diego’s Jacobs School of Engineering who led the student-run project. “Perhaps this was once a reasonable assumption, but advances in digital imaging and optics have made it easy to duplicate someone’s keys from a distance without them even noticing.” Professor Savage presents this work on October 30 at ACM’s Conference on Communications and Computer Security (CCS) 2008, one of the premier academic computer security conferences. In one demonstration of the new software system, the computer scientists took pictures of common residential house keys with a cell phone camera, fed the image into their software which then produced the information needed to create identical copies. In another example, they used a five inch telephoto lens to capture images from the roof of a campus building and duplicate keys sitting on a café table more than 200 feet away.
