Quick Summary

The Henry system is a method for classifying fingerprints, treating all ten fingers as a single unit. This system, developed by Sir Edward R. Henry, forms the basis for most fingerprint identification systems used in English-speaking countries. Fingerprints are unique to each individual and do not change over time, making them a reliable method for personal identification.12

The science of fingerprinting, known as dactyloscopy, involves analyzing the patterns of ridges on the fingers. These patterns, typically categorized as arches, loops, and whorls, are further classified using detailed characteristics. Modern police technology utilizes automated fingerprint identification systems (AFIS) to rapidly search through millions of digitized fingerprint records, aiding in criminal investigations.23
