摘要： 介绍了一种密码和指纹结合的系统，它采用密码作为指纹库的索引，索引到密码对应的特征模板，再和输入指纹进行验证，能克服密码容易被伪造和单独使用指纹验证耗时长的缺点；同时系统的指纹特征模板能自动更新，以反映使用者指纹的变化并完善原注册的特征模板，实验结果表明该系统具有较好的安全性，同时速度快、准确率高。

Abstract: A system combined with password and fingerprint is proposed. The input fingerprint does matching with a characteristic template that is retrieved from a fingerprints database with the password as index. The fraud of password is avoided and the high time consumption is decreased. Meanwhile the fingerprint characteristic template is updating during the service time to embody the changes of finger skin and perfect the original template. Experimental results show it is more secure, faster and more accurate than customary system.
