【摘要】：近年来,手指静脉识别作为新一代生物特征识别技术逐渐成为身份认证领域的研究热点,研究新型的手指静脉识别系统有助于手指静脉识别技术的应用和推广。云端服务器提供一种简单高效、安全可靠的运算服务,能够快速稳定的处理和存储数据。基于此,设计了一种基于云端的手指静脉识别系统,不仅能够提高手指静脉识别系统的识别效率,并能实现多台设备数据共享和信息的网络化管理。本文的主要工作如下:首先,为了实现采集设备的小型化,采用ARM处理器和嵌入式Linux操作系统,构建了嵌入式终端。嵌入式终端自动采集手指静脉图像,并通过网络将图像上传到云端服务器。其次,搭建了云端服务器环境。云端服务器搭载服务器软件,支持多台终端接入。然后,当接到终端上传的数据后,云服务器调用识别程序进行数据处理,并将识别结果返回给终端显示。最后,采用B/S(浏览器/服务器)架构模式,设计了手指静脉数据管理系统,用于远程管理用户信息。本文通过实验验证了系统的可行性。实验结果表明,本文设计的手指静脉云端识别系统不仅能够快速、稳定地实现身份认证,并且具有以下优点:(1)可实现数据采集与保存的分离,保障数据安全性;(2)可实现数据共享,只要用户信息在云端注册,任意一台嵌入式终端都可以通过接入云端实现身份认证;(3)可实现用户信息网络化管理。
[Abstract]:In recent years, finger vein recognition as a new generation of biometric identification technology has gradually become the research hotspot in the field of identification. The study of a new finger vein recognition system is helpful to the application and promotion of finger vein recognition technology. Cloud server provides a simple, efficient, secure and reliable computing service, which can process and store data quickly and stably. Based on this, a finger vein recognition system based on cloud is designed, which can not only improve the recognition efficiency of finger vein recognition system, but also realize the data sharing and information management of many equipments. The main work of this paper is as follows: firstly, in order to realize the miniaturization of the acquisition device, the embedded terminal is constructed by using arm processor and embedded Linux operating system. The embedded terminal automatically collects the finger vein image and uploads the image to the cloud server through the network. Secondly, the cloud server environment is built. Cloud server with server software, support multiple terminal access. Then, after receiving the data uploaded by the terminal, the cloud server calls the identification program to process the data and returns the result to the terminal to display. Finally, using the B / S (browser / Server) architecture, a finger vein data management system is designed for remote management of user information. The feasibility of the system is verified by experiments in this paper. The experimental results show that the finger vein cloud recognition system designed in this paper can not only quickly and stably realize identity authentication, but also has the following advantages: 1) can realize the separation of data collection and storage. As long as the user information is registered in the cloud, any embedded terminal can realize identity authentication by accessing the cloud.
