Claim One:
1. A biometric register, comprising: a feature extraction unit for performing preprocessing for a fingerprint to extract a feature point m for the fingerprint; a transformation function generation unit for generating a transformation function which is composed of an arbitrary rotation matrix and an arbitrary vector; and a template generation unit for transforming a coordinate of the feature point m using the generated transformation function, and organizing a fuzzy vault using a randomly generated fake feature point and a feature point m 1 applied by the transformed coordinate, thereby generating a one-time template, wherein the transformed function is represented by A 1 = ( cos ⁢ ⁢ α 1 - sin ⁢ ⁢ α 1 sin ⁢ ⁢ α 1 cos ⁢ ⁢ α 1 ) , ⁢ b 1 = ( b 11 b 12 ) , wherein A 1 is a rotation matrix and b 1 is a vector, and wherein the coordinate of the feature point m is transformed by 
 w 1 =A 1 w+b 1 , wherein w 1 is the transformed coordinate of the feature point m, w is the coordinate of the feature point m.
