碩士 === 元智大學 === 資訊研究所 === 87 === Traditional document processing is mainly done through paperwork. There exits several problems in it, such as, unauthorized changes of document contents, flow out-of-control during document circulation, and the document confidentiality. Information technology has helped greatly but not fully solved these problems yet. The emerging technology on Internet and World Wide Web suggests the idea of virtual office that provides a multi-user, standardized, and distributed environment that highly eliminated the affects of time and space. The idea of virtual office makes it possible for people in various locations to easily exchange, deliver, and share ideas, documents, and information. Nevertheless, issues regarding the security during document circulation, user identification and authorization, and system workflow design are still the major concerns while establishing an electronic documents system on the Internet. In this study, a prototype system is designed and implemented in an attempt to solve the problems mentioned. By using techniques such as, public key infrastructure, cryptography, and workflow model, the electronic documents system is implemented on the Internet with Secure Sockets Layer support. The system is designed to automate the document transmission and flow-control that in term will massively reduce the cost and time of document processing. It is also designed with security in mind that will keep the confidentiality of documents both on their storage and during their transmission.
