【摘要】：隨著當今社會信息化的快速發(fā)展與進步,人們的安全意識也在不斷的增強,信息的保密以及信息之間的傳遞也變的多樣化,尤其是對于一些高保密的場所,對出入人員的檢查越來越嚴格,通過什么方式來作為身份驗證的標準顯得尤為重要,傳統(tǒng)的一些身份驗證并不十分可靠,如身份證、工作卡等,基于生物學特征的身份驗證——指紋識別作為人體獨一無二的特征已經(jīng)占有較大的市場空間,它具有安全性高、實用性強等優(yōu)點,并且隨著人們年齡的增長,指紋并不會改變,因此,指紋識別成為了當今身份驗證的主要發(fā)展趨勢。指紋識別不能單獨處理數(shù)據(jù)和信息傳遞,但如果與嵌入式系統(tǒng)相結合,則會很大程度上提高指紋識別的作用,使得指紋識別不受空間的限制。本文分析了基于指紋特征識別的安全認證手段,借助藍牙無線通信和嵌入式技術應用到身份驗證領域,實現(xiàn)了指紋模塊采集到的指紋信息無線傳輸?shù)娇刂贫?使得指紋識別技術更廣泛的應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線藍牙模塊兩大部分,首先從模塊的性能包括價格、使用壽命、體積等對指紋采集模塊和藍牙模塊進行選型,指紋模塊主要分析指紋采集過程、數(shù)據(jù)處理以及最終成像,藍牙模塊主要從藍牙傳輸協(xié)議以及傳輸具體流程上進行介紹,最終確定方案,設計電路,以ARMSTM32為核心控制器,通過指紋采集模塊FPM10A,將指紋信息采集到控制器中,通過ARM發(fā)出控制信號,實現(xiàn)指紋信息的預存、辨識以及特征值的提取,利用軟件編程,對采集到的指紋進行成像,進一步的結合無線傳輸模塊GC-02,將提指紋的比對結果實時的送到上位機,以實現(xiàn)遠程實時的監(jiān)測指紋采集情況,本系統(tǒng)傳輸信號穩(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.
