In recent years, biometrics has developed rapidly with its worldwide applications for daily life. New trends and novel developments have been proposed to acquire and process many different biometric traits. The ignored challenges in the past and potential problems need to

The key objective of the book is to keep up with the new technologies on some recent theoretical development as well as new trends of applications in biometrics. The topics covered in this book reflect well both aspects of development. They include the new development in forensic speaker recognition, 3D and thermo face recognition, finger vein recognition, contact-less biometric system, hand geometry recognition, biometric performance evaluation, multi-biometric template protection, and novel subfields in the

The book consists of 13 chapters. It is divided into four sections, namely, theory and method, performance evaluation, security and template protection, and other applications. Chapter 1 explores the latest techniques which are being deployed in the various branches of speaker recognition, and highlights the technical challenges that need to be overcome. Chapter 2 presents a novel biometric system based on 3D and thermo face recognition, including specify data acquisition, image processing and recognition algorithms. In Chapter 3, the author proposes a scattering removal method for finger-vein image restoration, which is based on a biological optical model which reasonably described the effects of skin scattering. Chapter 4 gives an overarching survey of existing principles of contact-based hand geometry systems and mentions trends in the contact-less systems. Chapter 5 introduces a new subfield, namely, Genetic and Evolutionary Biometrics (GECs), which shows how GECs can be hybridized with a well-known feature extraction technique needed

Section 2 is a collection of two chapters on performance evaluation. Chapter 6 analyzes the efficiently and reliably whether the state-of-the-art speaker recognition techniques can be employed in this context, as well as the limitations and their strengths to be improved to migrate from old-school manual or semi-automatic techniques to new, reliable and objective automatic methods. Chapter 7 presents the performance evaluation of biometric systems related to three aspects: data quality, usability, and security. Security as respect to the
