An easy-to-understand synopsis of identification systems, presenting in simple language the process of fingerprint identification, from the initial capture of a set of finger images, to the production of a Rapsheet. No other single work exists which reviews this important identification process from beginning to end. We examine the identification process for latent (crime scene) prints and how they are identified with these systems. While the primary focus is automated fingerprint identifications, the book also touches on the emergence and use of fingerprints in other biometric systems.Criminal justice administrators, policy makers, and students of forensic science and criminal justice will find a reference to the known limitations and advantages of these systems.This book provides information as to the critical and continual need for properly trained individuals as well as an understanding of the direct and indirect costs associated with maintaining these systems. An understanding of the entire system and what it means will prove invaluable. Why are there missed identifications? Why are identifications made on one database that are not made on another database? Key terms and issues are included, and well as suggestions for improving the overall number of identifications.The book will go beyond process and also discuss issues such as interoperability, management strategies for large databases, contract development, lights out verification and several other issues which impact automated identifications. - The first comprehensive title on this subject area- Outlines in detail the entire process of fingerprint gathering and identity verification - The future of AFIS will is discussed, including national standards in developing multi-agency cooperation/interoperability (U.S.) in addition to the use of AFIS identification world-wide.

A system is described in which a fingerprint is manually coded by tracing certain ridges and noting events such as ridge endings and ridge beginnings.This code is sent by teleprinter to a central file where a computer identifies the fingerprint by comparing the code with codes previously entered in the file.The scheme for comparing codes is given along with some preliminary test results using typical fingerprints.(Author).

A procedure is described for computing a set of numerical descriptors that identify a single fingerprint.The procedure starts with the X and Y coordinates and the individual directions of the minutiae (ridge endings and bifurcations) of a fingerprint impression.Sets of descriptors are computed corresponding to groups or constellations of these minutiae.Descriptors corresponding to various fingerprint impressions are stored on magnetic tape.A fragment of a fingerprint impression such as occurs in a latent fingerprint may also be used.A second computer program reads the descriptors corresponding to two different fingerprint impressions from magnetic tape.A score is computed that indicates how well the two impressions match. Preliminary experimental results suggest that this procedure might be suitable as a basis for a single-fingerprint classification system.(Author).

The idea of The Fingerprint Sourcebook originated during a meeting in April 2002. Individuals representing the fingerprint, academic, and scientific communities met in Chicago, Illinois, for a day and a half to discuss the state of fingerprint identification with a view toward the challenges raised by Daubert issues. The meeting was a joint project between the International Association for Identification (IAI) and West Virginia University (WVU). One recommendation that came out of that meeting was a suggestion to create a sourcebook for friction ridge examiners, that is, a single source of researched information regarding the subject. This sourcebook would provide educational, training, and research information for the international scientific community.

Excerpt from A Semi-Automated Single Fingerprint Identification System A system is described in which a fingerprint is manually coded by tracing certain ridges and noting events such as ridge endings and ridge beginnings. This code is sent by teleprinter to a central file where a computer identifies the fingerprint by comparing the code with codes previously entered in the file. The scheme for comparing codes is given along with some preliminary test results using typical fingerprints.
