A person's fingerprints are based on the patterns of skin ridges (called dermatoglyphs) on the pads of the fingers. If the traced ridge ends without reaching the right side, it is necessary to drop perpendicularly to a point on a ridge directly below and continue the tracing up to the relative point nearest the right delta. An algorithm for assigning score for each value of the parameters was discussed. Forensic Science: Fundamentals & Investigations, Chapter 6 * Characteristics of Fingerprints There are 3 general fingerprint distinctions: ARCH WHORL LOOP About 5% About 30% About 65% of the population Arch An arch has friction ridges that enter on one side of the finger and cross to the other side while rising upward in the middle.
