Abstract
An apparatus for authentication of three-dimensional (3D) structures includes a projector (1510) for projecting a first pattern of illumination (1520) on the three-dimensional structure; a sensor (1525) for detecting a first reflected pattern (1540) from the three-dimensional structure; a computer (1530) for analyzing the first reflected pattern for a first pre-determined characteristic; and wherein the computer authenticates the three-dimensional structure if the pre-determined characteristic is present.
