【摘要】：随着当今社会信息化的快速发展与进步,人们的安全意识也在不断的增强,信息的保密以及信息之间的传递也变的多样化,尤其是对于一些高保密的场所,对出入人员的检查越来越严格,通过什么方式来作为身份验证的标准显得尤为重要,传统的一些身份验证并不十分可靠,如身份证、工作卡等,基于生物学特征的身份验证——指纹识别作为人体独一无二的特征已经占有较大的市场空间,它具有安全性高、实用性强等优点,并且随着人们年龄的增长,指纹并不会改变,因此,指纹识别成为了当今身份验证的主要发展趋势。指纹识别不能单独处理数据和信息传递,但如果与嵌入式系统相结合,则会很大程度上提高指纹识别的作用,使得指纹识别不受空间的限制。本文分析了基于指纹特征识别的安全认证手段,借助蓝牙无线通信和嵌入式技术应用到身份验证领域,实现了指纹模块采集到的指纹信息无线传输到控制端,使得指纹识别技术更广泛的应用于人们生活的各种需求中。本文研究主要分为指纹采集模块和无线蓝牙模块两大部分,首先从模块的性能包括价格、使用寿命、体积等对指纹采集模块和蓝牙模块进行选型,指纹模块主要分析指纹采集过程、数据处理以及最终成像,蓝牙模块主要从蓝牙传输协议以及传输具体流程上进行介绍,最终确定方案,设计电路,以ARMSTM32为核心控制器,通过指纹采集模块FPM10A,将指纹信息采集到控制器中,通过ARM发出控制信号,实现指纹信息的预存、辨识以及特征值的提取,利用软件编程,对采集到的指纹进行成像,进一步的结合无线传输模块GC-02,将提指纹的比对结果实时的送到上位机,以实现远程实时的监测指纹采集情况,本系统传输信号稳定,成本低,有很大的开发前景。
[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.
