Journal ArticleDOI
Enhancing security and privacy in biometrics-based authentication systems
TL;DR: The inherent strengths of biometrics-based authentication are outlined, the weak links in systems employing biometric authentication are identified, and new solutions for eliminating these weak links are presented.
Journal ArticleDOI
Generating Cancelable Fingerprint Templates
TL;DR: This paper demonstrates several methods to generate multiple cancelable identifiers from fingerprint images to overcome privacy concerns and concludes that feature-level cancelable biometric construction is practicable in large biometric deployments.
Journal ArticleDOI
A real-time matching system for large fingerprint databases
TL;DR: The approach integrates a number of domain-specific high-level features such as pattern class and ridge density at higher levels of the search and incorporates elastic structural feature-based matching for indexing the database at the lowest level.
Book
Guide to Biometrics
TL;DR: This complete, technical guide details the principles, methods, technologies, and core ideas used in biometric authentication systems and defines and explains how to measure the performance of both verification and identification systems.
Journal ArticleDOI
Adaptive flow orientation-based feature extraction in fingerprint images
TL;DR: A reliable method for extracting structural features from fingerprint images is presented and a “goodness index” (GI) which compares the results of automatic extraction with manually extracted ground truth is evaluated.
