Biometrics

Biometrics-Unique and Diverse Applications in Nature, Science, and Technology provides a unique sampling of the diverse ways in which biometrics is integrated into our lives and our technology. From time immemorial, we as humans have been intrigued by, perplexed by, and entertained by observing and analyzing ourselves and the natural world around us. Science and technology have evolved to a point where we can empirically record a measure of a biological or behavioral feature and use it for recognizing patterns, trends, and or discrete phenomena, such as individuals' and this is what biometrics is all about. Understanding some of the ways in which we use biometrics and for what specific purposes is what this book is all about

Naval Reserve support to information Operations Warfighting

Since the mid-1990s, the Fleet Information Warfare Center (FIWC) has led the Navy's Information Operations (IO) support to the Fleet. Within the FIWC manning structure, there are in total 36 officer and 84 enlisted Naval Reserve billets that are manned to approximately 75 percent and located in Norfolk and San Diego Naval Reserve Centers. These Naval Reserve Force personnel could provide support to FIWC far and above what they are now contributing specifically in the areas of Computer Network Operations, Psychological Operations, Military Deception and Civil Affairs. Historically personnel conducting IO were primarily reservists and civilians in uniform with regular military officers being by far the minority. The Naval Reserve Force has the personnel to provide skilled IO operators but the lack of an effective manning document and training plans is hindering their opportunity to enhance FIWC's capabilities in lull spectrum IO. This research investigates the skill requirements of personnel in IO to verify that the Naval Reserve Force has the talent base for IO support and the feasibility of their expanded use in IO.http://archive.org/details/navalreservesupp109451098

Sistema de reconhecimento biométrico baseado no electrocardiograma

Este projecto pretende criar uma plataforma do tipo framework, para desenvolvimento de software que permita a implementação de sistemas biométricos de identificação e autenticação pessoal, usando sinais electrofisiológicos. O sinal electrocardiograma (ECG) é uma característica biométrica em ascensão, existindo fortes indícios de que contém informação suficiente para discriminar um indivíduo de um conjunto vasto de população. Usa-se a framework desenvolvida para criar aplicações que permitam avaliar o desempenho de várias abordagens do estado da arte do reconhecimento biométrico, baseadas no ECG. A arquitectura típica destes sistemas biométricos inclui blocos de aquisição, préprocessamento, extracção de características e classificação de sinais ECG, utilizando tipicamente duas abordagens distintas. Uma das abordagens (fiducial) assenta em pormenores dos diferentes segmentos da forma de onda do sinal ECG, enquanto que a outra abordagem (nonfiducial) tem a vantagem de não depender criticamente desses pormenores. Neste projecto ainda será explorada uma nova variante numa abordagem (non-fiducial) baseada em compressão de dados. Finalmente, pretende-se ainda estudar o desempenho destas abordagens em sinais ECG adquiridos nas mãos, o que constitui um desafio, dado não existirem actualmente estudos sistemáticos usando este tipo de sinais

Biometric recognition in automated border control : a survey

The increasing demand for traveler clearance at international border crossing points (BCPs) has motivated research for finding more efficient solutions. Automated border control (ABC) is emerging as a solution to enhance the convenience of travelers, the throughput of BCPs, and national security. This is the first comprehensive survey on the biometric techniques and systems that enable automatic identity verification in ABC. We survey the biometric literature relevant to identity verification and summarize the best practices and biometric techniques applicable to ABC, relying on real experience collected in the field. Furthermore, we select some of the major biometric issues raised and highlight the open research areas

Fingerprint Recognition for Children

This document is the final report of the Fingerprint Recognition Study of Children below the Age of 12 Years . The key findings of the study are: • Growth has limited influence on fingerprint recognition • Size (in terms of the dimensions of the relevant fingerprint characteristics) does not constitute any theoretical barrier for automated fingerprint recognition. • Image quality (in terms of low contrast and distortion effects) is the ultimate problem for child fingerprints, and image quality is strongly influenced by size. • Relevant quality metrics for fingerprints need revision with regard to the children case. • Isotropic growth model may serve as a good approximation to cover changes over time. • Alternative acquisition devices for fingerprints should be seriously considered in the future. Apart from these major findings, the report provides a number of recommendations to improve the process of acquiring fingerprints from children.JRC.G.7-Digital Citizen Securit

Intelligent interface agents for biometric applications

This thesis investigates the benefits of applying the intelligent agent paradigm to biometric identity verification systems. Multimodal biometric systems, despite their additional complexity, hold the promise of providing a higher degree of accuracy and robustness. Multimodal biometric systems are examined in this work leading to the design and implementation of a novel distributed multi-modal identity verification system based on an intelligent agent framework. User interface design issues are also important in the domain of biometric systems and present an exceptional opportunity for employing adaptive interface agents. Through the use of such interface agents, system performance may be improved, leading to an increase in recognition rates over a non-adaptive system while producing a more robust and agreeable user experience. The investigation of such adaptive systems has been a focus of the work reported in this thesis. The research presented in this thesis is divided into two main parts. Firstly, the design, development and testing of a novel distributed multi-modal authentication system employing intelligent agents is presented. The second part details design and implementation of an adaptive interface layer based on interface agent technology and demonstrates its integration with a commercial fingerprint recognition system. The performance of these systems is then evaluated using databases of biometric samples gathered during the research. The results obtained from the experimental evaluation of the multi-modal system demonstrated a clear improvement in the accuracy of the system compared to a unimodal biometric approach. The adoption of the intelligent agent architecture at the interface level resulted in a system where false reject rates were reduced when compared to a system that did not employ an intelligent interface. The results obtained from both systems clearly express the benefits of combining an intelligent agent framework with a biometric system to provide a more robust and flexible application
