摘要
当今社会在很多领域中,对于安全保密的要求越来越高,由于选择传统的身份认证技术很容易被伪制,所以增加产品的安全可靠性就成了本设计的初衷。又因为目前国内应用于金融行业的现金款箱产品,都选择传统的身份识别技术,所以在款箱出入金库、运钞车押运途中以及存放在保管室等款箱流动过程中的安全性就受到了严重的威胁。
     鉴于目前市场对该类产品功能需求,基于原有现金款箱电子锁的智能特征,利用指纹识别技术的唯一性和可靠性,同时考虑指纹锁在流动性较大的行为中具有的安全联防优势,及更优越的授权能力,开发设计了基于现金款箱数据采集管理系统的指纹锁系统,本系统是基于MSP430单片机为MCU,设计了指纹采集识别为第一重身份认证,配合非接触射频IC卡和键盘密码输入二重身份认证,辅以非易失性大容量存储器,查询结果以LCD显示,并为系统安全可靠性的做了人性化设计。
     基于现金款箱数据采集管理系统的指纹锁系统的设计更具人性化的人机对话面板,强大的功能,为不同用户提供不同的需求。设计分为产品硬件和产品流动两部分,选择基于单片机的嵌入式系统作为开发核心,采用数据采集技术、指纹识别技术和加密技术,提高了系统的可靠性,产品流动部分使现金款箱在出入金库、押运途中等行为中具有更高的安全权限和智能化实时跟踪记录能力。
     鉴于单一的身份认证均存在弊端,选择多重认证能使款箱更加安全,本系统在设计时加入了指纹识别、IC卡和键盘密码多重身份认证,利用C51对MSP430为控制核心的系统进行设计控制系统,利用SQL Sever和C#创建数据库和管理平台,使产品更具人性化,且在占据市场份额时更具优势。
Security in many areas receives a great deal of attention increasingly from people. The traditional identity authentication technique is easy to be counterfeited, so the paper's original intention is to assure products of security and reliability. At present, the cash money box products of civil financial industry still use the traditional identity authentication technique, so the security, in the flowing processes of money box, for example, in and out vault, cash truck escorting and in storeroom, etc., is to be threatened seriously.
     Considering the current products' function requirement, based on electronic lock's intelligent features of the old cash money box, using uniqueness and reliability of fingerprint identification techniques, and fingerprint lock's higher security joint defense and super authorization ability, the fingerprint lock system was designed based on data acquisition system of cash money box. In system, MSP430 microprocessor is designed as the first identity authentication, non-contact RF IC and keyboard password input are designed as the second identity authentication, nonvolatile mass storage is also involved, and final result will be displayed by LCD, besides, the security and reliability of the system are personalized.
     Friendly interface and powerful functions of the fingerprint lock system meet demand for users. The system is divided into two parts:product hardware and product flow. Embedded system of MCU as core component, data collection, fingerprint identification and encryption techniques enhance the system's reliability. In the designing stage, the identification and encryption techniques were analyzed and argued systematically, so in the flowing process of money box, for instance,in and out vault, escort, etc.,it will be higher security limits and intelligent ability of tracking and recording.
     Considering disadvantages of single identity authentication and higher security of multiple authentications, the system includes fingerprint identification, IC and keyboard password techniques, etc. Using C51 to design control system based on MSP430, and SQL and C# to create database and management platform, the product will be more personalized and market share.
