【摘要】：隨著駕校考試越來(lái)越嚴(yán)格，考試逐步實(shí)行電子化。在這其中，身份認(rèn)證就顯得格外重要。目前駕�？荚囀褂玫南到y(tǒng)存在身份認(rèn)證單一、人機(jī)交互不友好、價(jià)格昂貴以及系統(tǒng)升級(jí)不方便等因素。本文提出了一套嵌入式身份認(rèn)證系統(tǒng)，能夠進(jìn)行脫機(jī)識(shí)別身份，認(rèn)證速度快、安全性高、便于安裝和升級(jí)維護(hù)等。 本文首先分析了身份認(rèn)證技術(shù)的發(fā)展?fàn)顩r，指出在IC卡中存放指紋信息，與現(xiàn)場(chǎng)采集到的指紋進(jìn)行比對(duì)，，能夠更好的實(shí)現(xiàn)人卡合一。其次，綜合硬件和軟件方面的考慮，課題提出了以S3C2440作為系統(tǒng)核心控制器，并根據(jù)需求搭建系統(tǒng)硬件平臺(tái)；對(duì)市場(chǎng)上眾多IC卡進(jìn)行比較后，課題選擇了復(fù)旦公司的FM1208卡作為指紋模板載體，并在分析其內(nèi)部結(jié)構(gòu)和原理的基礎(chǔ)上，設(shè)計(jì)出相應(yīng)的讀卡模塊；通過(guò)指紋模塊實(shí)現(xiàn)對(duì)人員的指紋采集、存儲(chǔ)、比對(duì)以及對(duì)IC卡內(nèi)部數(shù)據(jù)的控制操作；并根據(jù)需求設(shè)計(jì)相應(yīng)的車載信號(hào)采集模塊和電源部分。第三，針對(duì)系統(tǒng)硬件平臺(tái)的特點(diǎn)，完成u-boot及Linux內(nèi)核移植，并制作相應(yīng)的根文件系統(tǒng)；分析和設(shè)計(jì)了系統(tǒng)串口驅(qū)動(dòng)和車載信號(hào)信號(hào)采集驅(qū)動(dòng)；根據(jù)設(shè)計(jì)需求，完成了讀卡器模塊底層設(shè)計(jì)，實(shí)現(xiàn)IC卡的讀寫功能。第四，通過(guò)比對(duì)不同的GUI特點(diǎn)，系統(tǒng)選擇Qt/E作為界面設(shè)計(jì)；設(shè)計(jì)IC文件并存儲(chǔ)用戶信息；讀取IC卡中指紋數(shù)據(jù)，并與現(xiàn)場(chǎng)采集指紋進(jìn)行比對(duì)，最終實(shí)現(xiàn)身份認(rèn)證功能。 指紋識(shí)別技術(shù)與IC卡技術(shù)有機(jī)的結(jié)合，極大的提高了身份識(shí)別的安全性，同時(shí)通過(guò)界面化設(shè)計(jì)，也提高了人機(jī)交互的友好性。這為以后在駕校考試中的身份認(rèn)證提供了一個(gè)新的方向，具有廣闊的市場(chǎng)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.
