摘　　要：指纹识别技术属于生物特征识别技术的一种。指纹具有唯一性和不变性。针对指纹识别在各种需要身份认证的场合的广泛应用,设计了一款基于嵌入式技术的自动指纹识别系统(AFIS)。系统的硬件采用JC19指纹识别模块和基于Intel PXA270 ARM处理器的嵌入式UP-TECHPXA270 ARM平台;基于上述硬件开发了自动指纹识别软件,软件设计基于嵌入式Linux操作系统,采用模块化编程。利用所设计指纹识别系统分别对指纹录入、搜索、比对、删除及指纹库清空各功能进行了测试。结果表明系统的硬件和软件都能较好的工作,达到了预期的目的。The fingerprint identification technology is one of the biometric identification technologies. Fingerprints are unique and stable. Fingerprint identification has been widely used where the authentication is needed. An automatic fingerprint identification system （AFIS） has been designed on the basis of embedded technology in this paper. The hardware of system uses JC19 fingerprint identification module and UP-TECHPXA270 ARM platform, based on the Intel PXA270 ARM processor. The fingerprint identification software design is based on the above hardware and embedded linux operating system using the module programming method. All functions of loading, searching, matching, deleting fingerprint and emptying fingerprints of the whole system have been tested separately. The result demonstrates that both the hardware and software of system work well and expected purpose has been achieved.
