Key Code Recognition: Case Study of Automatically Deriving the Code of a Physical Key from Mobile Device Camera Images for the EVVA A key profile

This technical report tackles the problem of automatically recognizing the information encoded into a physical key (key code) from a photo taken with a mobile device camera, so that a reproduction (clone) can be be created from it. Conceptually, a person takes (a) photo(s) from a key using a mobile device camera. The key code is derived from these photos using computer vision techniques and can further be used by key manufacturers to clone the key – without requiring physical access to the key sample.
