The access control provided by a physical lock is based on the assumption that the information content of the corresponding key is private - that duplication should require either possession of the key or a priori knowledge of how it was cut. However, the ever-increasing capabilities and prevalence of digital imaging technologies present a fundamental challenge to this privacy assumption.
Using modest imaging equipment and standard computer vision algorithms, we demonstrate the effectiveness of physical key teleduplication - extracting a key's complete and precise bitting code at a distance via optical decoding and then cutting precise duplicates. In this paper, researchers describe their prototype system, Sneakey, and evaluate its effectiveness, in both laboratory and real-world settings, using the most popular residential key types in the U.S.
