P ractical Biometrics: From Aspiration to Implementation, Julian Ashbourn. This book concentrates on the implementation of biometric verification techniques, with specific regard to wide-scale public applications. Written from an operational rather than purely academic perspective, it serves as a practical guide, identifying scalability issues in applications that feature biometric verification techniques. Other topics include interoperability, both from a technical and operational perspective; ethnicity and the associated implications for biometric verification checks; and user psychology. The book also explores nondevicespecific issues such as human factors, the environment, privacy, and data protection. Springer; www.springer-ny.com; 185233-774-5; 180 pp.; $49.95.
