Fingerprint sample input apparatus for use in user authentication, determines aligned spectral data matrix determined from fingerprint sample and public data of fingerprint template

摘要

A receiver receives public data of a fingerprint template from a fingerprint verification device. An alignment matcher determines a rotation value and a translation value from the public data and fingerprint sample read by a fingerprint reader. A matrix generator determines an aligned spectral data matrix from the translation value, rotation value and fingerprint sample. A transmitter sends the matrix to the fingerprint verification device. Independent claims are also included for the following: (1) fingerprint verification device; (2) method for aligning fingerprint sample; and (3) method for fingerprint verification.
