To my assistants and coauthors who have always proved smart, outstanding, and prominent.

Contents

I met Professor Saeed, the principal author of this book, for the first time in 2009 at AGH University of Science and Technology, Krakw, Poland. I was invited as one of the keynote speakers and a researcher of behavioral biometrics in the International Multi-Conference on Biometrics and Kansei Engineering. My first impression of him was a true professor in an elegant suit, with high-quality speech, passionate approach to research, and unfailing kindness. Although 7 years have already passed, his humanity is abiding, and I have ever since constantly communicated with him as a researcher, a university educator, a journal editor, and an international conference chair.

Professor Saeed has achieved a great accomplishment by writing this book: New Directions in Behavioral Biometrics. Publishing this book has been a delightful event for me and many biometrics researchers. Based on the great achievement of his research team, this book includes a readable introduction, beneficial literature reviews, specific approaches, detailed algorithms, and useful experimental results of behavioral biometrics such as signature recognition, keystroke dynamics, gait analysis, and voice recognition.

Biometric technology using physiological characteristics has been widely applied, and many products that employ this technology are very popular, whereas biometric technology using behavioral characteristics has not received considerable attention. However, from a different point of view, research of the behavioral biometrics possesses the possibility of success and advancement. For a university student, a researcher, or a developer who is researching biometrics or developing an application system, this book will provide a clear path of basic information on behavioral biometrics and many hints for new discovery, all coming out of the extensive research experience of the author.

If, in the near future, a technology of identifying an individual based on writing style is developed, Professor Saeed will be easily identified because this book includes his passionate approach and a high degree of completion.

This book is the result of research conducted with major members of my international biometrics team on some selected topics in behavioral biometrics: a field of study related to the way people behave. As the reader might recall, the science of biometrics deals with biological measurementdescribing and measuring human features for the sake of identity recognition (personal authentication and identification or verification, or both). Biometrics is known in two categories: physiological and behavioral. Physiological biometrics is beyond the scope of this book, but some selected examples have been provided in another book by the author (see Biometrics and Kansei Engineering, Springer, New York, 2012). This book, though, will focus on the most popular and emblematic examples of behavioral biometrics, namely, signature (the way we write), dynamics of keystrokes or touchscreen use (how we use the keyboard or touchscreen to enter text), and gait (how we move our legs to walk). will deal with speech and speaker recognition, that is, the manner and art of combining vocal tracts, tongue, and lips to utter sounds and say words, which is sometimes considered to be a combination of physiological and behavioral features. All these human features are unique; they differ from one person to another, and that is why they can be used to distinguish people.

The content of the book is divided among five chapters. is a general introduction to the subject, showing the nature of each behavioral feature, and discussing how they are collected and prepared for measuring. It also discusses the advantages and disadvantages of using such features for user authentication or personal verification.

These chapters reflect the authors extensive research on the different examples of biometrics. We have published many detailed works and consequently received valuable feedback from the reviewers, readers, and conference participants whenever a research work was presented for discussion. Hence, I hope this book appears in a well-organized and readable form to students and researchers.
