摘要
在许多场合需要识别人身份的合法性,指纹识别就是其中的方法之一。指纹比对的正确率与其算法有着密切的关系。现讨论了TouchChip的TCRS1A指纹仪的使用性能,编制了一个将指纹存于IC卡中并进行比对的测试程序。通过运行,知其误识率很低,但传感器因表面人体油渍导致的指纹残留而提高了误识率。建议用户在使用前要充分考虑采用CMOS型指纹识别仪时指纹残留的影响。
There are many using requirements for verifying one＇s legitimacy, biometrics fingerprint distinction is one way. The right rate of the distinction is related to the computing method. The article discusses the properry of TCRS1A of TouchChip, and writes a program to compare the biometrics fingerprint between man and the data stored in IC card. As a result, the device has lowest FAR, but it is deeply influenced by the remaining print on the surface of the sensor, and it should be considered first in actual application.
