SYSTEM AND METHOD FOR AUTHENTICATING AN OPTICAL PATTERN

摘要

A system for authenticating an optical pattern created by exposing a magnetically sensitive material to one or more magnetic field sources. The system includes illumination sources configured to illuminate the optical pattern, 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, and a processor configured to access the memory and compare the reference optical data to the sensed optical characteristic data in order to authenticate the optical pattern.
