Highly secure optical key access control system utilizing unique optical refraction properties of non-duplicated transparent objects to secure premises or computer databases is disclosed. Said access control system includes optical key containing an optical element with unique refraction properties and unique access module comprising source of light, image capture array and electronic processor. An optical element of optical key is inserted to access module between light source and image catching array at initial and then several following prearranged positions and resulting set of unique refraction image appeared at surface of image catching array processed with electronic processor for comparison against the existing database of preauthorized refraction images in database. If resulting set of unique refraction image match with some set of preauthorized refraction images the access to premises or computer databases is permitted.
The method of highly secure optical key access control system comprising 1. recognizing with unique access module the optical element with unique refraction properties used as a key by directing light beam through medium and optical element from several different directions, catching resulting set of unique refraction pictures with image catching array placed at some distance from optical element at direction of refracted light beam, process resulting set of unique refraction pictures with electronic processor for comparison against the existing database of preauthorized sets of refraction pictures in database to permit or refuse access to protected premises or protected computer database.
An apparatus of highly secure optical key access control system comprising:
