Zusammenfassung:	Methods and apparatus for lock and key security, the lock including a light receptacle, a scatter pattern detecting module, and a locking mechanism, the key including a light source and a prism, the lock and key security including receiving, in the light receptacle of the lock, light transmitted by the light source in the key through the prism; identifying, by the scatter pattern detecting module, a scatter pattern of the received light; comparing, by the scatter pattern detecting module, the scatter pattern to a unique preauthorized pattern for operating the lock; if the scatter pattern matches the unique preauthorized pattern, switching, by the scatter pattern detecting module, the current locking state of the locking mechanism; and if the scatter pattern does not match the unique preauthorized pattern, maintaining the current locking state of the locking mechanism.
