Abstract
THE POSIDENT CONCEPT USES FINGER PRINT IDENTIFICATION SYSTEM TO COMPARE THE SUBJECTS LIVE FINGER PRINT WITH A STORED FINGER PRINT. THE STORAGE MEDIUM CAN BE ONE OF SEVERAL TYPES. A PHOTOGRAPHIC IMAGEIIS ONE METHOD OF STORAGE. DIGITAL DATA IN PROM IS A SECOND METHOD. THE ID CARD IS PLACED FON THE ELECTRO-OPTICAL CORRELATION DEVICE. A VIDEO CAMERA (VIDICON OR SOLID STATE CCD CAMERA) IS USED TO SCAN THE FINGER PRINT PHOTO AS WELL AS THE ACTUAL FINGER PRINT. THE KEY AND UNIQUE FEATURE OF THE OPTICAL SYSTEM IS THAT IT CAN UTILIZE VISIBLE OR NEAR INFRA-RED LIGHT TO SCAN THE FINGER PRINT IMAGES. THE CONTRAST BETWEEN THE FINGER PRINT RIDGES THAT CONTACT THE GLASS AND THE VALLEYS BETWEEN IS VERY DISTINCT. THE RESULT IS A HIGH CON TRAST, BINARY LEVEL SIGNAL, WHICH IS EASILY USED BY A DIGITAL PROCESSOR TO CORRELATE THE FINGER PRINT IMAGES.
