数字校园一卡通中的身份验证技术研究及应用

建设“数字校园”,实现校园管理、资源共享电子化是建设“数字中国”整个工程中不可缺少的部分。文中首先设计了一种高性能的射频卡读写器,并采用PSAM卡认证技术提高系统的安全性;接着介绍指纹识别技术,并提出一种基于纹线方向信息的自动指纹识别算法,在此基础上设计了一个以校园网为基础、以射频卡为载体、以指纹识别技术为身份认证手段的校园一卡通系统。该系统的实施提高了学校人事财务统一管理能力,实现了校园内的身份识别、电子货币、电子交易等功能。

Research and Application of Identification Technique in Digital Campus Card System

Building a digital campus,making campus management and sharing electronic resource are an indispensable part of constructing digital-China engineering.So in this paper,a RF card reader with the high capability is designed by using PSAM card to improve system security.And then,introduces the fingerprint recognition technique,and presents a new algorithm based on the line direction information.Finally designs a campus card system with the medium of campus network with RF card and the identification method of fingerprint recognition technology.Its implementation helps to centralize the management ability of improving the personnel and financial affairs,achieves identification in campus,electronic cash,electronic deal and so on.
