Abstract:
1. A system for authenticating, said system comprising: one or more illumination sources configured to illuminate an optical pattern of a magnetically sensitive material, said optical pattern having physical attributes resulting from said magnetically sensitive material having been exposed to a magnetic field during a curing process of said magnetically sensitive material, said magnetic field having been produced by a magnetizable material having been magnetically printed with one or more magnetic field sources; one or more sensors configured to generate sensed optical characteristic data when the optical pattern is illuminated; a memory configured to store a reference optical data associated with a reference optical pattern created by exposing a reference magnetically sensitive material to a reference magnetic field during a curing process of said reference magnetically sensitive material, said reference magnetic field having been produced by a reference magnetizable material having been printed with one or more reference magnetic field sources, said reference optical data corresponding to data generated by one or more reference sensors when the reference optical pattern is illuminated by one or more reference illumination sources; and a processor configured to access said memory and compare the reference optical data to the sensed optical characteristic data in order to authenticate the optical pattern.
