and “Keep It In Your Pocket Unless You Need To Use It.”
University of California, 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. In this “Sneakey” Computer Vision project, features of the key is extracted from the photograph and accordingly a duplicate of the key is produced. So it is time to blur out the your keys in the photograph, like you did for number plates, credit card numbers before publishing to facebook, flickr etc.
Thats how it works:
The keys used in the most common residential locks in the United States have a series of 5 or 6 cuts, spaced out at regular intervals. The computer scientists created a program in MatLab that uses user difiend keypoints to normalize the picture of the key and then measures the depth of each cut. The depth of each cut is the key’s bitting code, which together with basic information on the brand and type of key you have, is what you need to make a duplicate key.
