Biometric Solutions

In a complex, geographically mobile, electronically wired information society, the problem of identifying a person continues to pose a great challenge. Since the conventional technology of using a "personal identification number" (PIN) or password hardly meets the requirements of an authentication system, biometric-based authentication is emerging as the most reliable method. This text provides a collection of 16 chapters containing tutorial articles and other material in a unified manner. It covers the basic concepts, theories and characteristic features of integrating/formulating different facets of biometric solutions for authentication, with recent developments and significant applications in an e-world. It provides the reader with a basic concept of biometrics and an in-depth discussion exploring biometric technologies in various applications in an e-world. It also includes a detailed description of typical biometric-based security systems and coverage of how these issues are developed.
