Iris recognition technologies for identity management are already deployed globally in several large-scale nationwide biometric projects and are currently entering the mobile market. More recently, periocular recognition has been employed to augment the biometric performance of the iris in unconstrained environments where only the ocular region is present in the image. Iris and Periocular Biometric Recognition provides an overview of scientific fundamentals and principles of iris and periocular biometric recognition over six broad areas: an introduction to iris and periocular recognition; a selective overview of issues and challenges; soft biometric classification; security aspects; privacy protection and forensics; and future trends. With contributions from experts in industry and academia, this book is essential reading for researchers, graduate students and practitioners in biometrics and related fields.

"This wonderful book is the first one to address the rapidly emerging optical OFDM field. Written by two leading researchers in the field, the book is structured to comprehensively cover any optical OFDM aspect one could possibly think of, from the most fundamental to the most specialized. The book adopts a coherent line of presentation, while striking a thoughtful balance between the various topics, gradually developing the optical-physics and communication-theoretic concepts required for deep comprehension of the topic, eventually treating the multiple optical OFDM methods, variations and applications. In my view this book will remain relevant for many years to come, and will be increasingly accessed by graduate students, accomplished researchers as well as telecommunication engineers and managers keen to attain a perspective on the emerging role of OFDM in the evolution of photonic networks." -- "Prof.Moshe Nazarathy, EE Dept., Technion, Israel Institute of Technology"

As we continue to witness global macroeconomic downturn in many parts of the world, an evolution of some sorts is slowly happening in telecommunications, much as the same witnessed prior to the Dot-com era. There has been a huge paradigm shift in the Data Communication and Networking (DCN) technology from an orderly, predictable, moderate but-steady growth industry to a chaotic marketplace of disruptive technologies, rapidly changing regulations, complex mergers and acquisitions, and inorganic growth. Recent Advances in Broadband Integrated Network Operations and Services Management covers the principles of both wired and wireless communications of voice, data, images, and video and the impact of their business values on the organizations in which they are used. This reference book includes theoretical and practical works, relevant case studies, topical surveys, and research articles that address problems faced by telecommunication service providers, equipment manufacturers, enterprises, and policy makers in the areas of data communications and networking.
