Biometrics are body measurements and calculations related to human characteristics. Biometrics authentication or realistic authentication is used in computer science as a form of identification and access control. It is also used to identify individuals in groups that are under surveillance. Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals.
In this course, several key aspects of biometrics are covered. Wayman, A. Jain, D. Maltoni, D. Maio Eds , Springer, Preliminary Schedule:.

Dahm Rowan University ravi rowan. Shetty Tennessee State University. A Fuzzy-based Two-stage Biometric Sample Quality Evaluation System Abstract: Performance of biometric systems is highly dependent on the quality of the input samples captured by the sensing device.
Although measures are taken for capturing high quality images, but the authentication system mandates the analysis of captured images for selection of precise data. Limited research has focused on usability issues relating to how users perceive and use biometric systems. However, most of the studies in this area are modality-dependent such as the usability study presented by Theofanos et al. Ravi P.

Biometric identification [1—3] is a subject of active research, where new algorithms and sensors are being developed. The most widely used identification systems are based on fingerprints, hand geometry, retina, face, voice, vein, signature, etc.
Free delivery on qualified orders. Large-scale biometric systems traditionally undergo a series of tests beyond technology and scenario testing.
Typically, biometric evaluations require that an inde-pendent party design the evaluation, collect the test data, administer the test, and analyze the results. A benefit of this dataset is enabling the evaluation of how modern systems can produce results from legacy hard-copy records, which will continue to be used out of necessity by the criminal justice system.
Biometric systems should be designed and evaluated relative to their specific intended purposes and contexts rather than generically. Biometric systems: technology, design, and performance evaluation James L.
Wayman , Anil K. Biometric Systems provides practitioners with an overview of the principles and methods needed to build reliable biometric systems.

In particular it will be of interest to biometric solutions developers, project managers, system integrators and administrators, application programmers and consultants. Electronic security Performance Evaluation. Biometric performance evaluations can be classified into technology, scenario and operational evaluations. Technology evaluations test computer algorithms with archived biometric data collected using a "universal" algorithm-independent sensor; Scenario evaluations test biometric systems placed in a controlled, volunteer-user environment modeled on a proposed 3.
A biometric system is a system that allows the recognition of a certain characteristic of an individual using mathematical algorithms and biometric data. There are several uses of biometric systems.
There are systems that require enrollment upstream of users. Other identification systems do not require this phase. Phillips et al  define three basic types of evaluation of biometric systems: a technology evaluation; b scenario evaluation; and c operational evaluation. Technology evaluation: The goal of a technology evaluation is to compare competing algorithms from a single technology.

Growing popularity of biometrics in mainstream identification and authentication has made it vitally important to ensure that the performance of biometric systems, solutions and applications rates at an acceptable level. In any system or solution, performance evaluation and metrics boost confidence of prospective adopters. Biometric system evaluation is a procedure of quantifying the performance of a biometric recognition system under given conditions.
This book provides a good coverage of the technology, methods, and the core ideas of four leading biometric systems. The various real-world applications for these systems, the performance, current state of art are also described in details. It also discusses the benchmarks for comparing the performance and for system improvements.
Technology evaluation aims at measuring the performance of a biometric system, typ-ically, focusing on a particular system component. The evaluation is repeatable and usu-ally short in duration compared to the other two evaluation types. Second, biometric recognition is an inherently probabilistic endeavor.
Even in DNA analysis, there has been controversy and uncertainty over how to estimate distinctiveness. Expected Learning Outcomes: a A good understanding of. This methodology is intended for testing biometric performance when biometric systems are working under different environments. Evaluation of biometric systems includes all of the factors noted above as well as the analysis and assessment of technology, scenario, and operational test results and of the training process.
Fingerprint recognition plays an important role in many commercial applications and is used by millions of people every day, e. Fingerprint image segmentation is typically the first processing step of most fingerprint algorithms and it divides an image into foreground, the region of interest, and background. The contribution of this paper is threefold: firstly, we propose a novel factorized directional bandpass FDB segmentation method for texture extraction based on the directional Hilbert transform of a Butterworth bandpass DHBB filter interwoven with soft-thresholding. Secondly, we provide a manually marked ground truth segmentation for images as an evaluation benchmark. Thirdly, we conduct a systematic performance comparison between the FDB method and four of the most often cited fingerprint segmentation algorithms showing that the FDB segmentation method clearly outperforms these four widely used methods. The benchmark and the implementation of the FDB method are made publicly available.
