    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.
