Bahram Javidi, Joseph L. Horner and John F. Walkup

With the rapid advances in computers, CCD technology, image processing hardware and software, printers, scanners, and copiers, it is becoming increasingly simple to reproduce pictures, logos, symbols, money bills, or patterns. This has stimulated an interest in research, development, and publications1-8 in security technology. In the growing area of biometrics identification, optical techniques are being used in developing products for retinal scanning, hand geometry and vein recognition, and fingerprint identification.
