We propose a compact technique for encryption-verification that relies on the following elements: multifactor encryption, which permits the simultaneous verification of up to four factors; distortion-invariant ID tag for remote identification; near infrared (NIR) writing and readout of the ID tag signal for invisible transmission; and optical processor, based on joint transform pattern recognition by optical correlation, for automatic verification of information. A highly-reliable security system is obtained by joining the advantages of all these elements for the first time. A novel NIR ID tag is designed and built by using commonly available materials. The very ID tag content cannot be visually perceived at naked eye; it cannot be either copied, scanned, or captured by any conventional device. Experimental results based on the NIR ID tag are shown. The satisfactory results obtained demonstrate a new insight into the applications of the compact and efficient technique for high-secure identification systems.
