DEVICE AND METHOD FOR GENERATING CANCELABLE FINGERPRINT TEMPLATE FOR LOW-QUALITY IMAGES

摘要

An apparatus for generating a replaceable fingerprint template is disclosed. The fingerprint template generating apparatus includes a minutiae extractor for extracting minutiae from a user's fingerprint image, and a triangulation unit for performing Delaunay triangulation to generate a plurality of triangles from the extracted minutiae, each of the a vector generator for generating a plurality of vectors corresponding to each of the plurality of triangles; and a vector converter for generating the user's fingerprint template by multiplying a matrix made of the plurality of vectors by an arbitrary matrix.
