The Henry Classification System is a long-standing method by which fingerprints are sorted by physiological characteristics for one-to-many searching.

In 1896, Sir Edward Richard Henry developed a fingerprint classification system that uses all fingerprints (hence, also called a 10-digit system). Prior to the modification by the FBI, the Henry system consisted of 4 classifications system.

Henry Classification System: A Summary Primary Each finger has a definite numerical value when a whorl type pattern is present. The total of these values make up the Primary. The numerator is made up of the total sum of the values present …

Henry (1900) made an extensive study of occurrence of fingerprints and indexed them into 8 major classes. The 8 classes are shown above. The four different whorl classes can be combined into one class: Whorl (W). The Henry system with five classes are shown above.

Classification of Fingerprints: Henry System riginal system developed by Sir Edward Richard Henry in 1896. Unfortunately, it could only accommodate files of up to 00,000 sets of prints, after which, it became too cumbersome. The FBI further modified the system by adding additional extension t the first step in classification is essentially the sa

Henry used a fraction-type primary classification which took the accrued values of the even numbered fingers as the numerator and the accrued value of the odd numbered fingers as the denominator.

Whenever a Whorl Pattern appears in a finger, the associated value of that finger is added to the base value of 1. The major differences between the American and Henry Systems are the values which are assigned to the each of the fingers and the manner in which those vaules are accrued.

The Galton-Henry system of fingerprint classification, published in June 1900, was officially introduced at Scotland Yard in 1901 and quickly became the basis for its criminal-identification records.

In the Henry System, sets of fingerprints were given a primary classification, based on the distribution of patterns in the fingers. Extensions were added to the Henry system of classification by the FBI.

Dr. Henry Faulds proposed a classification system in 1880, which influenced later developments. Sir Francis Galton published 'Finger Prints' in 1892, detailing a classification system with three main patterns: loops, whorls, and arches.
