A number of crucial societal applications like international border crossing, electronic
commerce, and welfare disbursement require reliable person recognition systems.
Traditional person authentication methods based on passwords and identity
documents often fail to meet the stringent security and performance demands of
these applications, which in turn has spurred active research in the field of biometric
recognition. Biometric recognition, or simply biometrics, is the science of establishing
the identity of a person based on physical or behavioral attributes such as fingerprint,
face, iris, and voice. Biometric systems are based on the premise that many
of the physical or behavioral attributes of humans can be uniquely associated with
an individual. By capturing these attributes using appropriately designed sensors,
representing them in a digital format, and comparing this recorded data against the
data acquired from the same person at an earlier time instance, it is possible to automate
the process of person recognition. Thus, biometric recognition can be viewed
as a pattern recognition problem, where the machine learns the salient features (patterns)
in the biometric attributes of an individual and robustly matches such patterns
efficiently and effectively.
Biometric recognition, or simply biometrics, is the science of establishing the identity of a person based on physical or behavioral attributes. It is a rapidly evolving field with applications ranging from securely accessing one’s computer to gaining entry into a country. While the deployment of large-scale biometric systems in both commercial and government applications has increased the public awareness of this technology, "Introduction to Biometrics" is the first textbook to introduce the fundamentals of Biometrics to undergraduate/graduate students. The three commonly used modalities in the biometrics field, namely, fingerprint, face, and iris are covered in detail in this book. Few other modalities like hand geometry, ear, and gait are also discussed briefly along with advanced topics such as multibiometric systems and security of biometric systems. Exercises for each chapter will be available on the book website to help students gain a better understanding of the topics and obtain practical experience in designing computer programs for biometric applications. These can be found at: http://www.csee.wvu.edu/~ross/BiometricsTextBook/. Designed for undergraduate and graduate students in computer science and electrical engineering, "Introduction to Biometrics" is also suitable for researchers and biometric and computer security professionals.
