Abstract

A novel opto-electronic system has been developed using a diffractive code for the machine verification of the contents of the electronic memory of integrated-circuit (IC) cards to impeded attacks against IC card security. Through engineering of the diffractive microstructures, the intensity distribution of the diffracted light can be tailored for optical codes of high security, uniqueness and unambiguous identification. By measuring the diffraction properties of the optical code, the authenticity of the IC card can be checked. The diffractive code further provides a link to the information stored in the IC memory. The demonstrated diffractive-optical code is of the WORM type; that is, it is a write-once, read-many times memory. The data recorded in the diffractive optical code are compared to the data of the IC-card electronic memory using an encryption algorithm and are used to prevent tempering and alteration of the data stored in the IC-card electronic memory.
