【摘要】 国家各级政府机关、企事业单位以及各类学术组织每年都要召开很多会议,或举办各类培训班,作为会议的组织方,需要确定参会人员、发放通知、组织信息注册、参会人员身份确认等工作。而当前普遍采用的人工核对证件以及使用智能卡或无线射频识别(RFID)卡证件的身份认证手段,普遍存在信息易泄露、证件易伪造、资源浪费等缺点。在安全形势日益严峻及倡导绿色环保的今天,利用信息技术设计和实现一个严密的会议身份认证系统是十分需要的。针对上述问题,按照软件工程的设计思想,本文重点研究基于二维码和人脸识别技术的会议身份认证系统及其构建方法。首先,采用用例图、时序图、类图并结合传统的流程图对会议身份认证系统进行了全面的需求分析。在需求分析的基础上对系统中的会议信息注册模块、人脸识别模块、数字签名模块以及二维码编码/解码模块进行了详细的分析和设计。系统实现的功能主要包括:(1)会议信息注册:主要是对参会人员的注册信息的进行采集,包括了注册信息采集和注册信息处理两个模块;(2)人脸识别:主要负责参会者身份的识别,包了注册时人脸识别和会议签到时人脸识别两个子模块;(3)数字签名:该模块主要用于注册时对参会者的有效信息进行签名以及参会者注册签到时对签名信息进行验证,以防止了二维码凭证被伪造。(4)二维码编码/解码:该模块主要是利用QR码对参会者的注册信息进行编码和解码操作。本文所设计的系统在已经实际工作中进行了推广和试运行。运行效果及用户的相关反馈表明,该系统不仅可以防止参会者信息泄露以及身份仿冒等问题,而且极大地提高了会议管理的工作效率,为会议的安全有序进行提供了必要的技术保障。更多还原

【Abstract】 Government agencies,enterprise and public institution,universities and other units held many conferences each year.Organizational meeting is complex thing,involving in the determine and notification of participants,registration,sign in,authentication of participants,statistical information and so other things.The current practice of identification is manual checking,smart card,RFID card,etc.There are some shortages in these methos.For example,information leakage,forging certificates,wasting of resource and so on.Nowdays,An automated,intelligent,green authentication system is a pressing need because of the complex security situation and green initiatives.Aim at solving the above problems,this paper focuses on the construction of conference authentication system based on two-dimensional bar code and face recognition technology.Firstly,this paper takes sequence diagram,use case,class diagram to provide insight into the requirements.Based on the requirements analysis,detailed analysis and design is made for the information registration module,face recogintion module,digital signature module and the two-dimensional bar code encoding/decoding module.System functions realized are as follows:(1)Conference information registration.It is mainly collecting the registration information of the system attendances,including information collection module and information handle module.(2)Face recognition.It is mainly authentication,including two submodule separately used in registration and sign-in.(3)Digital signature.It is used mainly to sign the attendance’s information and check the signature for validity to avoid forging the two-dimensional bar code certificate.(4)Encoding and decoding two-dimensional bar code.It is used to encode and decode the QR-code that contains the registration information of the attendances.The system that introduced in this paper has started trials.It concludes that the system can not only prevent information leakage and identity theft but also improve the meeting management efficiency through the operation effect and the users’feedback.The system provides the necessary technical guarantee to ensure the coferences proceed safely and orderly.更多还原
