Book Description
A new generation of contactless fingerprint capture devices has recently emerged. These devices provide the ability to capture a fingerprint without making physical contact with the finger. There is anecdotal evidence that the process of capturing a fingerprint by making contact with it also introduces a certain amount of physical distortion to the finger being pressed against the collection medium. It is hypothesized that because contactless collection devices do not need to make physical contact with the finger bring captured, the resulting collections from contactless devices are expected to have no mechanical deformation introduced to the finger and provide better intraoperability and as well as better consistency between captures from the same device.This hypothesis was rejected in that observations in this study showed that contact collection devices have more consistency and less variability between successive captures using the same device.

Book Description
This report describes computational comparison measurements as well as match error analysis applied to fingerprint images collected by researchers of the National Institute of Standards and Technology (NIST) in May of 2019. Fingerprint images from 200 Federal Employees were collected using both contact and contactless acquisition devices, including both stationary devices and mobile smartphone devices. Match scores from two different matchers were used to calculate False Negative Identification Rate (FNIR) and False Positive Identification Rate (FPIR) at two operational thresholds appropriate to each of the matchers. These values are displayed in graphical form across eight devices for each of ten finger combinations. Overall error performance is compared via Area Under Curve across devices for each of ten finger combinations as well as across finger combinations separately for each of the eight devices. Contact-to-contact interoperability remains superior to contactless-to-contact, but multiple finger combinations improve match performance of contactless devices.

Book Description
This document details efforts undertaken by the National Institute of Standards and Technology (NIST) to develop measurements and a protocol for the evaluation of contactless (touchless) fingerprint acquisition devices. Contactless fingerprint capture differs fundamentally from legacy contact fingerprinting methods, and poses novel problems for image quality evaluation and challenges relative to interoperability with contact fingerprints that populate large repositories maintained by law enforcement and Federal Government organizations. For contact acquisition, the fingerprint impression is a first-order transfer of the 3D friction ridge structure to the recording surface. The third dimension of the curved finger surface is effectively removed by pressure against the planar recording surface. The 3D topography of the ridges and furrows are transferred with low ambiguity to the recording surface as dark ridges (points of contact) and lighter furrows (lesser or no contact). Contactless images by comparison, in most cases, are third-order renderings of an original photographic representation, itself a 2D optical projection of the 3D structure of the finger. The appearance of this projection is subject to variability as low- or moderately-controlled lighting interacts with the 3D geometry of the finger, the friction ridge structure superimposed on the finger, and the geometry of the presentation of the finger to the contactless device. The photograph must then be subjected to various image processing methods to infer the ridge structure for rendering as a fingerprint similar in appearance to legacy contact captures. The rendering process is the source of numerous errors relative to contact captures. Despite problems with image quality, this early study finds contactless fingerprints of the devices examined to be usable in some applications, with qualifications, including one- to-many matching against small databases.

Book Description
The development of technologies for the identi?cation of individuals has driven the interest and curiosity of many people. Spearheaded and inspired by the Bertillon coding system for the classi?cation of humans based on physical measurements, scientists and engineers have been trying to invent new devices and classi?cation systems to capture the human identity from its body measurements. One of the main limitations of the precursors of today’s biometrics, which is still present in the vast majority of the existing biometric systems, has been the need to keep the device in close contact with the subject to capture the biometric measurements. This clearly limits the applicability and convenience of biometric systems. This book presents an important step in addressing this limitation by describing a number of methodologies to capture meaningful biometric information from a distance. Most materials covered in this book have been presented at the International Summer School on Biometrics which is held every year in Alghero, Italy and which has become a ?agship activity of the IAPR Technical Committee on Biometrics (IAPR TC4). The last four chapters of the book are derived from some of the best p- sentations by the participating students of the school. The educational value of this book is also highlighted by the number of proposed exercises and questions which will help the reader to better understand the proposed topics.

Book Description
In the recent years, a number of recognition and authentication systems based on biometric measurements have been proposed. Algorithms and sensors have been developed to acquire and process many different biometric traits. Moreover, the biometric technology is being used in novel ways, with potential commercial and practical implications to our daily activities. The key objective of the book is to provide a collection of comprehensive references on some recent theoretical development as well as novel applications in biometrics. The topics covered in this book reflect well both aspects of development. They include biometric sample quality, privacy preserving and cancellable biometrics, contactless biometrics, novel and unconventional biometrics, and the technical challenges in implementing the technology in portable devices. The book consists of 15 chapters. It is divided into four sections, namely, biometric applications on mobile platforms, cancelable biometrics, biometric encryption, and other applications. The book was reviewed by editors Dr. Jucheng Yang and Dr. Norman Poh. We deeply appreciate the efforts of our guest editors: Dr. Girija Chetty, Dr. Loris Nanni, Dr. Jianjiang Feng, Dr. Dongsun Park and Dr. Sook Yoon, as well as a number of anonymous reviewers.
