高效指纹考勤系统的研究与设计

针对现有考勤系统中存在的代打卡和班次设计不够灵活等问题，提出了一种基于指纹识别的考勤系统。系统采用的核心算法是对Anil Jain等人提出的细节匹配算法的一种改进，利用指纹细节点的组合解决了指纹识别中普遍存在的非线性形变问题。系统采用面向对象设计方法，后台数据库可以设置多种。实验和测试结果表明，这种基于自动指纹识别技术的考核系统能够满足现代办公的需求。

Research on an Efficient System of Work Attendance Using Fingerprint Identification

The traditional system for checking on work attendance can work by fraud. For example, it can't prevent employee from checking for each other. In this paper, an efficient system based on fingerprint identification technology is designed and a minutia matching algorithm which modifies Jain's algorithm. Not the minutiae themselves but those around them are used to compose feature vectors, so the algorithm can better distinguish two images from different fingers and is more robust to nonlinear deformation. Experiments and the feedback opinion of users have shown that the system can be widely applied into modern management.
