Apparatus and method for polynomial reconstruction in fuzzy vault system

摘要

How to Restore a polynomial in the purge bolt system of the present invention is used to restore the polynomial receives a matching feature points selecting a combination of feature points; Generating a system of equations using the selected feature points in combination; Determining whether the root is present in the system of equations; And if the presence of near-simultaneous equations using a combination of feature points includes a step of restoring the polynomial. In accordance with the present invention by the user by using the high-speed processing possible polynomial restoration method can be applied to various bolt purge system by restoring the polynomial in real time without the need for a separate key.
