A new optical authentication and security system using optical variable nano/micro-structures (OVNs) is presented. The proposed design features a passive authentication method using a simple optical system found in common fabrication facilities. The passive authentication is obtained by insertion of an OVN image directly on a processing layer or divided between multiple layers of the fabrication process. Authentic fabrication process is validated when the proper alignment (reconstructed image, for example) at the end of the fabrication is achieved. Simple proof-of-concept devices with the OVN-based authentication system are presented along with the optical images of the resulting authentication patterns.
