【摘要】：随着驾校考试越来越严格，考试逐步实行电子化。在这其中，身份认证就显得格外重要。目前驾校考试使用的系统存在身份认证单一、人机交互不友好、价格昂贵以及系统升级不方便等因素。本文提出了一套嵌入式身份认证系统，能够进行脱机识别身份，认证速度快、安全性高、便于安装和升级维护等。本文首先分析了身份认证技术的发展状况，指出在IC卡中存放指纹信息，与现场采集到的指纹进行比对，，能够更好的实现人卡合一。其次，综合硬件和软件方面的考虑，课题提出了以S3C2440作为系统核心控制器，并根据需求搭建系统硬件平台；对市场上众多IC卡进行比较后，课题选择了复旦公司的FM1208卡作为指纹模板载体，并在分析其内部结构和原理的基础上，设计出相应的读卡模块；通过指纹模块实现对人员的指纹采集、存储、比对以及对IC卡内部数据的控制操作；并根据需求设计相应的车载信号采集模块和电源部分。第三，针对系统硬件平台的特点，完成u-boot及Linux内核移植，并制作相应的根文件系统；分析和设计了系统串口驱动和车载信号信号采集驱动；根据设计需求，完成了读卡器模块底层设计，实现IC卡的读写功能。第四，通过比对不同的GUI特点，系统选择Qt/E作为界面设计；设计IC文件并存储用户信息；读取IC卡中指纹数据，并与现场采集指纹进行比对，最终实现身份认证功能。指纹识别技术与IC卡技术有机的结合，极大的提高了身份识别的安全性，同时通过界面化设计，也提高了人机交互的友好性。这为以后在驾校考试中的身份认证提供了一个新的方向，具有广阔的市场前景。
[Abstract]:With the driving test is more and more strict, the implementation of electronic examination gradually. In this one, the identity authentication is particularlyimportant. System is currently driving test of the single authentication, human-computer interaction is not friendly, expensive and inconvenient upgrade and other factors. This paper presents a set of embedded authentication system can be offline identity authentication, fast speed, high safety, convenient installation and maintenance and upgrading.
This paper first analyzes the development of identity authentication technology, pointed out that the fingerprint information stored in the IC card, and the collected fingerprint matching, can better realize one card one. Secondly, comprehensive hardware and software considerations, thesis takes S3C2440 system as the core controller, and build the system hardware platform based on needs; to compare the many IC card on the market after the subjects choose thefudan FM1208 card as a fingerprint template vector, and based on the analysis of the internal structure and principle, designs the corresponding card reader module; through the fingerprint module to realize fingerprint acquisition, storage of personnel, alignment and control operation of the IC card internal data the design of vehicle; and the signal acquisition module and the corresponding power supply according to the demand. Third, according to the characteristics of the hardware platform, and completed the u-boot Linux kernel transplantation, and production The root file system; system analysis and design of the serial port driver and vehicle signal acquisition driver; according to the design requirement, the card reader module design and implementation of IC card reader function. Fourth, by comparing the different features of GUI, Qt/E is selected as the system interface design; design the IC file and store user information; read the fingerprint data in IC card, and compares with the field fingerprint, finally realizes the function of identity authentication.
The organic combination of fingerprint identification technology and IC card technology, greatly improve the security of the identity, at the same time through the interface design, but also improve the friendly man-machine interaction. This is the driving test authentication provides a new direction, has broad market prospects.
