| Summary: | 碩士 === 國立交通大學 === 資訊管理所 === 87 === Electronic Data Interchange (EDI) is defined as the corresponding standard of both or multi-communities which is used as the transferring protocol of the structured information through the electronic communication channels. However, the electronic data interchange over Internet (EDIINT) is an integrated mechanism which does not only support the EDI standard but also can be used under the Internet environment. Its purpose emphasizes at the integration of many existing Internet transferring schemes and offers an open exchanging standard for the data interchange and communication. In this study, we focus at the EDIINT integration from different aspect. Besides, we provide the evidence of supporting EDIINT from the business operation point of view, examine the evolution of this standard by comparing the criterion of either the close or open property of the network and the EDI standard. Fulfilling the requirement of open transferring standards and network communications, we propose a complete business EDIINT approach through mail system by combining the existing UN/EDIFACT and MIME format and prove its feasibility.
In addition, there are increasing need for business multimedia applications such as digital watermarking image, video and audio data. To provide the interrelationship between the EDI standard and the multimedia information, our system supports the business multimedia service and confirms its capability of integration.
At the stage of communication, we also encapsulate the security control mechanism. The scheme completes the actual implementation for the safe Internet business electronic data interchange and transmission. Our study shows that it is easy to integrate the EDI translator with the mail agent for SMTP service, to transfer EDI strings and business multimedia under the reliable PGP/MIME protocol. Due to the speedy commercialization of the Internet and the fast prosperity of the E-commerce, we expect that our integrated technology study could behave as the reference for the development and the applications in the associated fields.
