项目摘要

In these a few years, there are a lot of workstations and termiinals connected into single universal network. These workstations will proceed a lot of variety documents such as very personal information, published data, electric magazine, private mail and so on. Establishing a public common database connected to open network will be important subject to realize a high efficient system shared by mass of customers at reasonable cost. A safe-deposit box is very convenient facility, because many kind of assets and important docments of indivisuals are stored with hight security at reasonable cost. The same function of this system will bave to be exist in future information society in the single universal network system. We have proposed secure document image management system which manages private information at resonable cost with high security.To realize real secure system in such open facility, there are two main problem. They are leakage and illegal occupation. The leakage means the content of document can be thrown out by somebody who is not the autliorized person. The illegal occupation means an injured function of database management occurred by mass of prescribed message that have been kept and are increasing in the database storage.To solve above problems, we have studied following items.1. Concreat system configuration and basic functions2. Network access protocol in deposit and takeout procedure to keep high security3. Database management protocol for secure document management4. Customer identificaion scheme using feature of physical characteristics such as sensed data of fingerprint5. Secure key sharing schemes using smartcard with no pre-communication6. Scramble algorithm for document image using Soace Filling CurveAnd we have constructed real simulation system using G4 FAX, ISDN network, workstations and smart card system in order to evaluate the protocols of proposed system at the point of security atid efficiency.

在这几年中，有许多工作站和终端连接成一个通用的网络。这些工作站将处理大量的个人信息、公开数据、电子杂志、私人邮件等各种文档，建立一个与开放式网络相连的公共公共数据库将是实现以合理的成本为广大用户共享的高效系统的重要课题。保险箱是非常方便的设施，因为许多种资产和个人的重要文件都以合理的成本存储在高安全性。在未来的信息社会中，这种系统的功能将存在于单一的通用网络系统中。我们提出了一种安全的文档图像管理系统，它以合理的成本管理私人信息，具有很高的安全性，要在这样的开放设施中实现真实的安全系统，主要有两个问题。它们是渗漏和非法占用。泄密是指文件内容可能被非授权人所泄露。非法占用是指在数据库存储器中保留大量规定的信息，并且这些信息还在不断增加，从而导致数据库管理功能受损.具体的系统配置和基本功能2.存款过程中的网络访问协议，以保持高安全性3.安全文档管理的数据库管理协议4.使用物理特性的特征（例如指纹的感测数据）的客户识别方案5.安全的密钥共享方案，使用无预通信6。利用Soace填充曲线实现文档图像置乱算法并利用G4传真机、ISDN网络、工作站和智能卡系统构建了真实的仿真系统，从安全性和效率的角度对所提出的系统协议进行了评估。
