摘要:近年来学生课堂缺课频率日益增高,通过课前点名来保障课堂教学质量的措施也逐渐体现出了耗费时间、效率低下等弊端,针对这些问题,采用Android客户端与服务器端数据交互,设计并实现了基于安卓指纹识别的考勤系统,该系统利用指纹具有终身不变性和唯一性的特性,使用学生的指纹信息进行课堂考勤记录,保证了考勤记录的准确性。进行签到的同时也启用了手机的定位服务,将学生的位置信息存放在考勤记录表中,GPS与移动网络定位在很大程度上减小了定位误差,经过测试,该系统基本实现了所有功能,考勤记录清晰准确,为高校课堂考勤工作带来了极大便利。

Abstract: In recent years, the frequency of students' absence in class is increasing day by day. The measures to ensure the quality of classroom teaching through roll call before class has gradually reflected the disadvantages of time-consuming and low efficiency. Aiming at these problems, this paper designs and implements an attendance system based on Android fingerprint identification by using data interaction between Android client and server. The system uses a fingerprint to have lifetime invariance and uniqueness Using students' fingerprint information to record class attendance, which ensures the accuracy of attendance records. At the same time, the mobile phone location service is also enabled for checking in, and the location information of students is stored in the attendance record form. GPS and mobile network positioning greatly reduce the positioning error. After testing, the system basically realizes all the functions, and the attendance record is clear and accurate, which brings great convenience for college class attendance work.

1 背景

指紋识别技术作为生物体特征识别技术之一在新世纪逐渐成熟[1],随着手机不断更新换代,手机的指纹识别功能已日益完善并成为手机不可或缺的功能,指纹识别技术是同虹膜识别、人脸识别等其他生物识别技术相比,目前最成熟且价格便宜,又非常适合应用于手机的生物特征识别技术[2],该技术也已广泛应用于日常生活生产中,所以手机指纹识别功能的前景也非常广阔。但根据调查,国内大部分Android手机的指纹认证功能都只局限于用来解锁手机,仅有个别软件将其应用于手机支付上,其他软件很少将指纹识别技术使用到App的功能逻辑当中,所以做一个基于安卓指纹识别的考勤系统不仅是一个新的尝试,更是一个挑战。……
