0引言指纹识别作为生物识别领域中的重要分支之一,是现阶段被广泛运用的一种实用技术,也是科技领域的研究重点课题。在二十世纪八十年代初期,我国就已经开始了对指纹识别的研究。而随着电子设备的更新以及在人们日常工作、生活领域中的运用,使得各种智能卡、门禁控制、计算机以及ATM的普及应用,也使得人们对于身份识别技术提出了更高的要求,并迫切要求研发出更便捷、安全、准确的识别技术,即指纹识别认证技术。
0 Introduction Fingerprint recognition, as an important branch in the field of biometrics, is a practical technique that is widely used at this stage. It is also a key research topic in science and technology field. In the early 1980s, our country started the research on fingerprint identification. With the popularization and application of electronic equipment and the application in people’s daily work and life field, the popularization and application of various smart cards, access control, computers and ATM also make people have higher requirements for the identification technology and urgently Requires the development of more convenient, secure and accurate identification technology, namely fingerprint authentication technology.
