【摘要】：自动柜员机,又称ATM,是一种利用磁卡或智能卡介质的方式实现金融交易的自助服务设备。客户通过ATM做交易时,需先将持有的磁卡或智能卡插入到ATM机中,ATM读取介质数据之后提示客户输入介质密码,系统认证通过客户输入的密码后才可进行交易。当前ATM此种认证方式存在安全性差、易伪造、易被窃取等缺点。人脸识别技术的出现,是解决传统认证方式缺点的方法。它具有防伪性强、不易伪造、特征唯一性等优点,然而当前极少有银行把人脸识别技术应用到ATM系统中。本课题的任务是以ATM机认证系统为研究对象,将人脸识别技术应用到ATM机的认证系统上,并且设计一套网络环境下高负载、高可用、通用的人脸识别认证系统解决方案。以此来解决当前ATM机认证系统遇到的问题。其中主要需要解决的问题是如何将人脸识别技术应用到ATM系统中、如何获取客户的身份证标准照然后用于系统进行人脸识别匹配、人脸识别匹配完成后如何发送彩信告知客户识别匹配的结果及操作现场、如何支持认证系统高并发访问、负载均衡与灾备机制的需求。本论文开篇先阐述课题的研究背景以及意义,然后对国内外人脸识别技术当前现状及发展进行分析,接着阐述把人脸识别技术应用到ATM系统中可行性的理论依据。之后介绍人脸识别技术的概念、技术原理以及人脸识别技术的特色与优势。接着对本论文研究内容进行功能性需求分析及非功能性需求分析,然后介绍人脸识别认证系统的总体架构。另外,介绍人脸识别认证系统需要集成的人脸识别摄像头、短信平台外部设备。完成系统架构及外部设备介绍之后开始逐步构建系统。其中包括API桩的设计与实现,构建内部通信模块、外设服务模块、流程控制模块、接口封装;服务端的设计与实现,构建通信模块、彩信中心模块、数据库访问模块、第三方系统访问模块、主流程控制模块;路由控制端的设计与实现,构建内部通信模块、路由规则;数据库表设计;ATM认证系统改造;最后基于路由控制实现人脸识别认证系统的负载均衡与灾备机制方案。完成人脸识别认证系统构建后,通过用于自动化测试与性能测试的软件工具,利用测试软件对人脸识别认证系统进行压力测试,根据测试结果分析系统负载均衡与灾备机制是否有效,人脸识别认证系统的性能可否满足高并发的业务量。
[Abstract]:ATM (automatic teller machine) is a kind of self-service equipment which realizes financial transaction by means of magnetic card or smart card medium.When a customer makes a transaction through ATM, he must insert the magnetic card or smart card into the ATM to read the medium data and prompt the customer to enter the medium password, and the system authenticates through the password entered by the customer before the transaction can be carried out.Current ATM this kind of authentication way has the shortcoming such as the security, is easy to forge, is easy to be stolen and so on.The appearance of face recognition technology is a method to solve the shortcomings of traditional authentication methods.It has the advantages of strong anti-counterfeiting, hard to forge, unique features and so on. However, at present, very few banks apply face recognition technology to ATM system.The task of this paper is to apply face recognition technology to ATM authentication system, and to design a set of high load, high availability and general face recognition authentication system solution under network environment.In order to solve the current ATM authentication system encountered problems.The main problem that needs to be solved is how to apply face recognition technology to ATM system, how to obtain the standard photos of the customer's ID card and then apply it to face recognition matching.How to send MMS to inform customers of the matching result and operation site after face recognition matching is completed, and how to support the requirements of authentication system with high concurrent access, load balancing and disaster preparedness mechanism.At the beginning of this paper, the research background and significance of the subject are described, then the present situation and development of face recognition technology at home and abroad are analyzed, and the theoretical basis for the feasibility of applying face recognition technology to ATM system is expounded.Then it introduces the concept and principle of face recognition technology, as well as the features and advantages of face recognition technology.Then the functional requirements analysis and non-functional requirements analysis are carried out, and then the overall framework of face recognition authentication system is introduced.In addition, the face recognition authentication system needs the integrated face recognition camera and the external equipment of the short message platform.After completing the introduction of the system architecture and external equipment, we began to build the system step by step.It includes the design and realization of API pile, the construction of internal communication module, peripheral service module, process control module and interface encapsulation, the design and implementation of service end, the construction of communication module, MMS center module, database access module,Third party system access module, main process control module, design and implementation of routing control terminal, construction of internal communication module, routing rules, database table design and ATM authentication system transformation;Finally, the load balancing and disaster preparedness scheme of face recognition authentication system based on routing control is implemented.After completing the construction of the face recognition authentication system, through the software tools used for automated testing and performance testing, the test software is used to carry out the stress test on the face recognition authentication system.According to the test results, this paper analyzes whether the load balancing and disaster preparedness mechanism of the system is effective, and whether the performance of the face recognition authentication system can satisfy the high concurrent traffic.
