Abstract
In order to effectively reduce the running time of fingerprint feature data matching algorithm and improve the matching accuracy. This paper designs and proposes a fingerprint feature data equivalent matching algorithm based on distributed computing. In the process of de-counterfeiting, the method of combining distance de-counterfeiting with structure de-counterfeiting is adopted. The information of minutiae feature points for subsequent matching, sampling information of corresponding ridge and direction of minutiae points are obtained by ridge tracking method. On this basis, use the fingerprint matching algorithm based on the congruent triangle to match the extracted minutiae feature points, so as to achieve the purpose of matching fingerprint feature data equally. The simulation results show that the proposed algorithm can effectively reduce the running time and improve the matching accuracy, which fully verifies the practical application value of the algorithm.
