We start with a narrow definition, designed as much to limit the scope of our inquir y as to determine it. “Biometric technologies” are automated methods of verify TI - Biometric Systems: An Introduction to Biometric Authentication Systems DA - 2005-01-01 UR - https://www.deepdyve.com/lp/springer-journals/biometric-systems-an-introduction-to-biometric-authentication-systems-Ngd0fv0970 DP - DeepDyve ER -
