Abstract
Three-dimensional density key authentication employs a solid three-dimensional key, opaque to visible light, having varying three-dimensional density. A first three-dimensional reader-sensor scans the three-dimensional key and creates a first digital density map of the three-dimensional key, or/or a hash thereof. An authentication server Information Handling System (IHS), operatively coupled to the first three-dimensional reader-sensor preloads the first digital density map or hash, and maps a user, action, operation and/or the like with the three-dimensional key. A second three-dimensional reader-sensor scans the three-dimensional key, creates a second digital density map of the three-dimensional key, and/or a hash thereof, and sends the second digital density map or hash, to the authentication server IHS, for the authentication server IHS to compare the second digital density map or hash, with the first, pre-loaded, digital density map or hash, for authorizing access by the user, authorizing the action, authorizing the operation and/or the like.
