Who invented fingerprint scanner?

Answer 1

Alec Jeffreys Has Invented The Fingerprints.

That depends a great deal on what kind of fingerprint scanner you are referring to. There are quite a few different technnologies used for fingerprint scanning. As an example - the first person to answer this question referred to Professor Sir Alec Jeffreys whodeveloped techniques for"genetic (DNA)fingerprinting" used by forensic scientists and law enforcement world wide. Some of his technologies would qualify as a "fingerprint scanner" in that context. More likely the person posing the question was wondering about technologies for capturing fingerprints from the fingers of individuals in a form that could be used for later retrieval and comparison.

All the proposed methods for capturing fingerprints can be grouped into two major families: solid-state fingerprint readers and optical fingerprint readers. The procedure for capturing a fingerprint using a sensor consists of rolling or touching with the finger onto a sensing area, which according to the physical principle in use (optical, ultrasonic, capacitive or thermal) captures the difference between valleys and ridges. Depending on which type of sensor you are interested in, you have a different "inventor". To complicate matters even further, the way the scanner processes the captured information will vary. Some try to capture the entire fingerprint as a high resolution digital image. Other systems willonly capture a characteristic fraction of the fingerprintwith enough resolution to distinguish between most fingerprints. The former is necessary for forensic analysis, the latter is usually good enough for access control.

In short, there is no one inventor of the fingerpring scanner.

In 1963, Mitchell Trauring of Hughes Research Lab, published the first paper “Automatic Comparison of Fingerprint Ridge Patterns,” on automated personal identification. In 1975, the FBI began funding the development of scanners and extracting technology. It took decades to develop methods of digital file compression that maintained image quality, classification, extraction of elements and matching (M40 algorithm). In 1994, the Integrated Automated Fingerprint Identification System (IAFIS) competition was held. Lockheed Martin was selected to build the IAFIS. The system was to address digital fingerprint acquisition, ridge characteristic extraction and ridge characteristic pattern matching. Aside from the development of software applications that read fingerprints or other permanent traits, the first use of cataloguing of fingerprints was by Juan Vucetich in 1891 in Argentina. Later, criminal identification based on physical elements (anthropometry) by Aphonse Bertillon, of France, improved the practice. Later, in the mid-1800s, Francis Galton created a fingerprint classification system. The Henry Classification system was used from the late 1800s to sort fingerprints by physiological characteristics. Named for Sir Edward Henry, it was developed in British India with Hem Chandra Bose and Azizul Haque.
