基于麒麟系统下指纹识别系统设计研究

摘要

On the basis of the system of fingerprint recognition,the system is safe,reliable and efficient;The fingerprint authentication method is adopted instead of the password authentication system;Fingerprint chip and fingerprint sensor internal communication,the composition of the fingerprint module,to ensure the safety and reliability of fingerprint information. Through the construction of the fingerprint PAM module,the preparation of fingerprint module driver,the design of QT based application interface method;By running in kylin system safe and reliable fingerprint detection system, QT application software of fingerprint module,combined with the general cross platform,kylin system based on PAM QT application software,it is concluded that the system has the advantages of reliable operation,simple design,easy to transplant and other characteristics,has a certain practical value,can be widely used in Linux system platform.%基于中标麒麟系统下的指纹识别系统,以安全、可靠和快捷的登录系统为目的;实现了指纹技术认证方式代替密码认证方式登录系统;采用指纹芯片和指纹传感器内部通讯,组成指纹模块的方法,确保指纹信息安全可靠.通过了构建指纹底层PAM模块、编写指纹模块驱动、设计基于QT应用界面的方法;通过指纹系统在麒麟系统上安全可靠的运行,QT应用软件对指纹模块的检测,结合QT应用软件的跨平台性、麒麟系统PAM构架的通用性,得出该系统具有运行可靠,设计简单,容易移植等特点,具有一定实用价值,可以广泛的使用在Linux系统平台上.
