【摘要】：隨著當(dāng)今社會(huì)信息化的快速發(fā)展與進(jìn)步,人們的安全意識(shí)也在不斷的增強(qiáng),信息的保密以及信息之間的傳遞也變的多樣化,尤其是對(duì)于一些高保密的場(chǎng)所,對(duì)出入人員的檢查越來(lái)越嚴(yán)格,通過(guò)什么方式來(lái)作為身份驗(yàn)證的標(biāo)準(zhǔn)顯得尤為重要,傳統(tǒng)的一些身份驗(yàn)證并不十分可靠,如身份證、工作卡等,基于生物學(xué)特征的身份驗(yàn)證——指紋識(shí)別作為人體獨(dú)一無(wú)二的特征已經(jīng)占有較大的市場(chǎng)空間,它具有安全性高、實(shí)用性強(qiáng)等優(yōu)點(diǎn),并且隨著人們年齡的增長(zhǎng),指紋并不會(huì)改變,因此,指紋識(shí)別成為了當(dāng)今身份驗(yàn)證的主要發(fā)展趨勢(shì)。指紋識(shí)別不能單獨(dú)處理數(shù)據(jù)和信息傳遞,但如果與嵌入式系統(tǒng)相結(jié)合,則會(huì)很大程度上提高指紋識(shí)別的作用,使得指紋識(shí)別不受空間的限制。本文分析了基于指紋特征識(shí)別的安全認(rèn)證手段,借助藍(lán)牙無(wú)線通信和嵌入式技術(shù)應(yīng)用到身份驗(yàn)證領(lǐng)域,實(shí)現(xiàn)了指紋模塊采集到的指紋信息無(wú)線傳輸?shù)娇刂贫?使得指紋識(shí)別技術(shù)更廣泛的應(yīng)用于人們生活的各種需求中。本文研究主要分為指紋采集模塊和無(wú)線藍(lán)牙模塊兩大部分,首先從模塊的性能包括價(jià)格、使用壽命、體積等對(duì)指紋采集模塊和藍(lán)牙模塊進(jìn)行選型,指紋模塊主要分析指紋采集過(guò)程、數(shù)據(jù)處理以及最終成像,藍(lán)牙模塊主要從藍(lán)牙傳輸協(xié)議以及傳輸具體流程上進(jìn)行介紹,最終確定方案,設(shè)計(jì)電路,以ARMSTM32為核心控制器,通過(guò)指紋采集模塊FPM10A,將指紋信息采集到控制器中,通過(guò)ARM發(fā)出控制信號(hào),實(shí)現(xiàn)指紋信息的預(yù)存、辨識(shí)以及特征值的提取,利用軟件編程,對(duì)采集到的指紋進(jìn)行成像,進(jìn)一步的結(jié)合無(wú)線傳輸模塊GC-02,將提指紋的比對(duì)結(jié)果實(shí)時(shí)的送到上位機(jī),以實(shí)現(xiàn)遠(yuǎn)程實(shí)時(shí)的監(jiān)測(cè)指紋采集情況,本系統(tǒng)傳輸信號(hào)穩(wěn)定,成本低,有很大的開發(fā)前景。
[Abstract]:With the rapid development and progress of information technology in today's society, people's security awareness is also constantly enhanced, the confidentiality of information and the transmission of information has become diversified, especially for some places with high security. The inspection of entry and exit personnel is becoming more and more strict. How to use it as the standard of authentication is particularly important. Some traditional authentication is not very reliable, such as identity card, work card and so on. As a unique feature of human body, fingerprint identification based on biological characteristics has occupied a large market space. It has the advantages of high security, strong practicability, and with the increase of people's age. Fingerprint will not change, so fingerprint identification has become the main trend of identity verification. Fingerprint identification can not handle data and information transfer separately, but if it is combined with embedded system. It will greatly improve the role of fingerprint identification, so that fingerprint recognition is not limited by space. This paper analyzes the security authentication method based on fingerprint feature identification. With the help of Bluetooth wireless communication and embedded technology, the fingerprint information collected by the fingerprint module is wireless transmitted to the control terminal. Fingerprint identification technology is more widely used in people's life in various needs. This research is mainly divided into fingerprint acquisition module and wireless Bluetooth module. Firstly, the performance of the module includes price, service life. The volume of fingerprint acquisition module and Bluetooth module selection, fingerprint module analysis of fingerprint acquisition process, data processing and final imaging. Bluetooth module mainly from the Bluetooth transmission protocol and transmission process are introduced, the final determination of the scheme, design circuit, ARMSTM32 as the core controller, through the fingerprint acquisition module FPM10A. The fingerprint information is collected into the controller, and the control signal is sent out by ARM. The fingerprint information is stored, identified and the characteristic value is extracted. The fingerprint is imaged by software programming. Further combined with the wireless transmission module GC-02, the comparison results of fingerprint extraction are sent to the upper computer in real time to realize remote real-time monitoring of fingerprint collection. The system transmits stable signal and low cost. There are great prospects for development.
