PURPOSE: A false feature point generating method and fuzzy bolt generating method using the same are provided to generate fuzzy bolt by inserting a false feature point and to generate angle information. CONSTITUTION: A false feature point is generated by using a coordinate and angular information of a feature point(740). The false feature point is generated on a false line(750). The correspondence coordinate of the feature point satisfies a fuzzy vault polynomial. The fuzzy bolt polynomial information is removed(760). The false line segment is moved in parallel.
