摘　　要：身份识别一直以来是安全领域的重要课题,其中人类指纹作为最具特征的生物体特征之一,有典型的个体唯一性与发育不变性的特征,所以常常被用于身份验证领域。但基于点模式的传统指纹识别算法的缺陷,以及近年来人造指纹的出现,使这项本来为解决身份验证安全性而发展起来的技术,自身的安全性成为了制约其广泛应用的技术瓶颈。提出了点-线-面三步匹配算法,通过软件仿真证明该算法可以达到很高的识别精度,可以实现接近千分之一的等错误率。Identity recognition has always been an important topic in the field of security.As one of the most characteristic biological features,human fingerprint has typical characteristics of individual uniqueness and development invariance,so it is often used in the field of identity verification.However,the shortcomings of traditional fingerprint recognition algorithm based on point pattern and the emergence of artificial fingerprint in recent years make this technology,which is originally developed to solve the security of authentication,have security problems that cannot be ignored.This paper proposes a three-step point-line-plane matching algorithm.In the software simulation,it is proved that the algorithm can achieve a high recognition accuracy,and an equal error rate of nearly one thousandth.
