摘要： Provided a secure pattern recognition method. The method includes: receiving data and generating a probe by converting the received data into a template for pattern recognition; accessing a gallery that is a template registered and stored in advance; determining a region to which the probe belongs and obtaining the center point of the region; obtaining a hash value of the center point and coordinate of the probe; and determining whether or not the hash value of the center point and a hash value stored in the gallery are equal and determining whether or not the probe and the gallery are classified into the same class by calculating whether or not the coordinate of the probe is inside a decision boundary configured with thresholds on the basis of the coordinates of the center point.

摘要： Provided is a data protection technique that converts original data into a secure form so that even if data registered to a system or database is leaked, information relating to original data cannot be exposed from the leaked data. Accordingly, a method of generating a template for protecting data is provided, wherein the method includes: generating a positive numbered (n) registration feature vector g (g=[g1, g2, . . . , gn]T); generating a positive number m (m

摘要： A method and apparatus for extracting a face feature to construct a face search system having a high recognition rate are provided. The method includes calculating an average image of each of a plurality of candidates having one or more face images to which different weights are given according to an order in which the face images are acquired and calculating a total average image of all face images of the plurality of candidates, calculating a between-class scatter matrix based on a difference between each candidate's average image and the total average image and a within-class scatter matrix based on a difference between each candidate's average image and each candidate's predetermined face image of the one or more face images, and generating a base vector that maximizes a criterion defined by a ratio between the between-class scatter matrix and the within-class scatter matrix.

摘要： An apparatus and method for biometrics are provided. The apparatus includes a user registration unit, a user authentication unit, and a transform key storing unit. The user registration unit store a second registration template that transforms a first registration template generated from user biological data using a random orthogonal matrix and random vector. The user authentication unit transforms a first authentication template generated from input biological data the random orthogonal matrix and random vector used in the user registration unit, comparing with the second registration template, and thus performs user authentication. The transform key storing unit provides the random orthogonal matrix and the random vector to the user registration unit and the user authentication unit.
