Cutaneous Biometrics

Biometrics in dermatology is an essential tool where data evaluation results in valid interpretations. This book will be the first in this area. One part of the book will describe principal aspects of dermatological research focussing on practical advice. A special part will cover applied biometrics to provide the clinician and researcher with state-of-the-art guidelines to assess the severity of common skin diseases. An additional aspect that will be of interest to pharmacologists addresses pharmacologic assays.

This handbook covers the essential subject areas of cutaneous biometrics, including acne, aging, genetics, eczema, psoriasis, atopic dermatitis, rosacea, wound healing, and more. Erythema of rosacea and the risk of skin ulceration associated with oral nicorandil therapy are covered in detail. Various areas of acne are addressed, including acne severity grading, the assessment of general health and quality of life in patients with acne, and the effect of automated online counseling on clinical outcomes and quality of life among adolescents with acne vulgaris. Other topics include the development and validation of a clinical scale for the evaluation of forearm skin photoaging and a scoring system for mucosal disease severity. This is an ideal reference for biomedical engineering researchers and clinicians working in the field of dermatology interested in a deeper understanding of cutaneous biometrics and how it can be applied to their work. This book also: Broadens reader understanding of the importance of creating meaningful dermatological patient outcome measurements and the use of the physician global assessment in a clinical setting to measure and track patient outcomes Details the guidelines on the measurement of ultraviolet radiation levels in ultraviolet phototherapy

Biometric technologies, such as finger- or facial-scan, are being deployed across a variety of social contexts in order to facilitate and guarantee identity verification and authentication. In the post-9/11 world, biometric technologies have experienced an extraordinary period of growth as concerns about security and screening have increased. This book analyses biometric systems in terms of the application of biopolitical power – corporate, military and governmental – on the human body. It deploys cultural theory in examining the manner in which biometric technologies constitute the body as a target of surveillance and as a data-information object. The book thereby provides a comprehensive overview and critical analysis of both the local and global ramifications of biometric technologies.

This comprehensive handbook addresses the sophisticated forensic threats and challenges that have arisen in the modern digital age, and reviews the new computing solutions that have been proposed to tackle them. These include identity-related scenarios which cannot be solved with traditional approaches, such as attacks on security systems and the identification of abnormal/dangerous behaviors from remote cameras. Features: provides an in-depth analysis of the state of the art, together with a broad review of the available technologies and their potential applications; discusses potential future developments in the adoption of advanced technologies for the automated or semi-automated analysis of forensic traces; presents a particular focus on the acquisition and processing of data from real-world forensic cases; offers an holistic perspective, integrating work from different research institutions and combining viewpoints from both biometric technologies and forensic science.

This book addresses biometrics from a biomedical engineering point of view. Divided into five sections, it discusses topics including the influence of pathologies on various biometric modalities (e.g. face, iris, fingerprint), medical and security biometrics, behavioural biometrics, instrumentation, wearable technologies and imaging. The final chapters also present a number of case studies. The book is suitable for advanced graduate and postgraduate students, engineers and researchers, especially those in signal and image processing, biometrics, and biomedical engineering.

Recent advances in biometrics include new developments in sensors, modalities and algorithms. As new sensors are designed, newer challenges emerge in the algorithms for accurate recognition. Written for researchers, advanced students and practitioners to use as a handbook, this volume captures the very latest state-of-the-art research contributions from leading international researchers. It offers coverage of the entire gamut of topics in the field, including sensors, data acquisition, pattern-matching algorithms, and issues that impact at the system level, such as standards, security, networks, and databases

With an A–Z format, this encyclopedia provides easy access to relevant information on all aspects of biometrics. It features approximately 250 overview entries and 800 definitional entries. Each entry includes a definition, key words, list of synonyms, list of related entries, illustration(s), applications, and a bibliography. Most entries include useful literature references providing the reader with a portal to more detailed information.

Fingerprints have been widely used as a practical method of biometrics authentication or identification with a significant level of security. However, several spoofing methods have been used in the last few years to bypass fingerprint scanners, thus compromising data security. The most common attacks occur by the use of fake fingerprint during image capturing. Imposters can build a fake fingerprint from a latent fingerprint left on items such as glasses, doorknobs, glossy paper, etc. Current mobile fingerprint scanning technology is incapable of differentiating real from artificial fingers made from gelatin molds and other materials. In this work, the adequacy of terahertz imaging was studied as an alternative fingerprint scanning technique that will enhance biometrics security by identifying superficial skin traits. Terahertz waves (0.1-10 THz) are a non-ionizing radiation with significant penetration depth in several non-metallic materials. Several finger skin features, such as valley depth and sweat ducts, can possibly be imaged by employing the necessary imaging topology. As such, two imaging approaches 1) using quasi-optical components and 2) using near-field probing were investigated. The numerical study is accomplished using a commercial Finite Element Method tool (ANSYS, HFSS) and several laboratory experiments are conducted to evaluate the imaging performance of the topologies. The study has shown that terahertz waves can provide high spatial resolution images of the skin undulations (valleys and ridges) and under certain conditions identify the sweat duct pattern.
