Book excerpt: Excerpt from Manual and Computerized Footprint Identification For personal identification, the use of fingerprints is the most common and most developed technique. However, other dermatoglyphic areas on palms, toes and soles of the feet can also serve to uniquely identify an individual. This paper describes an identification system utilizing the sole print of the right foot. The area of the sole start ing at the base of the toes and running for about 70 mm toward the heel is used. Prints may be obtained by inking and pressing the sole on a flat surface or by internal reflection photography utilizing a light source, prism, and camera.2 The latter resulting high-contrast image resembles an inked print. This principle applies when one observes, through a glass of water, the prints of the fingers holding the glass. Figure 9 was made from an-internal reflection photograph and shows the area of the sale that is used. If a technician is given two dermatoglyphic prints of the same area, such as the soles of the feet, he can immediately tell by inspection of the prints Whether they are from the same person. In making this identification, he utilizes minute details in the prints, particularly, ridge endings and bifurcations in the ridges that are hereafter referred to as minutiae. When an unknown print is to be searched against a file of prints, making a positive identification is a minor problem compared to the task of finding the matching print in the file. To facilitate finding a print in a file, it is classified using the gross patterns that occur in the ridges. The resulting classification is then used to locate the print in the file. The classification of a search print should agree closely enough with the classification of a file print that only a few prints from the file need to be compared with the search print. The remainder of this paper is divided into two parts. Part 1 describes a system for manually classifying, filing, and searching prints from the right foot. Part 2 describes a method of coding and storing right-footprint information in a computer memory so that a computer can identify an unknown footprint by comparing its code with other codes previously stored in its memory or mass store.
