This book offers a scholarly examination of innovative biometric recognition technologies, focusing on palmprint, finger-knuckle-print (F-K-P), palm-vein, dorsal-hand-vein, and multi-modal hand-based recognition systems. These hand-based biometrics are highly valued in both academics and industry communities. For example, hand-based biometrics have been successfully developed for several practical applications such as the ‘Amazon One’ and ‘WePalm’. The significance of this monograph lies in its comprehensive analysis of state-of-the-art hand-based biometric recognition methods. It provides a systematic overview of various traits and recent technological advancements, offering readers insights into the practical applications and theoretical foundations of these emerging biometric modalities. The content encompasses detailed discussions on feature extraction, matching algorithms, and fusion techniques, highlighting their implications for enhancing authentication accuracy and security. The primary benefits of this book include its thorough coverage of advanced hand-based biometric recognition, its presentation of the latest research findings, and its exploration of cross-disciplinary applications. Besides this, we will comprehensively introduce the concepts and methods for these hand-based biometrics, which provides the readers with an interesting and foundational understanding for practical applications highly related to human life.
