This paper describes a proposed fingerprint coding station using a disk-based microcomputer and a digital input tablet.
Abstract
The microcomputer has a terminal display, a digital input tablet, and floppy disk storage. The digital input table is used to provide x-y coordinates of selected points on the fingerprint to the computer. The station can classify fingerprints for 10-print filing and searching. It is readily adaptable for latent print coding. The computer program controls the entire coding operation. Illustrations depict the various fingerprint pattern types, and a table shows the entered data and codes generated for each pattern type. The equipment and techniques discussed show considerable promise for lowering the costs and increasing the accuracy of coding fingerprint cards. The overall initial costs for equipment will vary depending upon the needs of the user. A simple station with one floppy 5-inch disk drive would cost less than $3,000, while a system suitable for coding, filing, and searching in a small bureau might cost about $8,000. The system is currently in the experimental stage. Future research will focus on combining 10-print and latent print searches in small to medium files. Six references are included.
