디지털 콘텐츠의 내용이 다양해지고 유통 구조가 복잡해짐으로 인하여 발생할 수 있는 문제들을 해결하기 위한 방안으로 모바일 환경에서 디지털 콘텐츠를 유통하는 전자상거래 모델을 제안하였다. 무선 환경에서의 온라인 유통 과정은 기존의 오프라인이나 유선 네트워크와는 다른 요소들이 많이 포함되어 있다. 더구나 디지털 저작물인 멀티미디어 콘텐츠는 쉽고 빠르게 불법 복제되고 전파될 수 있다. 이러한 환경 하에서 디지털 콘텐츠의 저작권과 관련된 당사자들의 권리와 이익을 보호할 수 있는 체계가 필요하다. 본 논문에서는 멀티미디어 유통 프레임워크인 MPEG-21에 기반 하여 무선 환경에서의 콘텐츠 유통 전자상거래 프레임워크를 제안하였다. 이 모델은 디지털 저작권 관리 시스템에 적용되어 전자상거래 시장에서 온라인 유통에 있어서 거래 당사자들 사이의 상호 권리 침해 방지를 위한 방법으로 활용될 수 있다.

Recently, many companies and consumers are using Internet to sell and buy goods and manage their businesses. And for most companies, they have Electronic Commerce system and Enterprise Resource Planning (ERP) system. But the two systems manage separately and the data are not integrative. So it is hard to mangement the system alike and the costs may be higher than the system which has intergrated information. ebXML-based Electronic Catalog (e-Catalog) can provide intergrated information. In this paper, we took a manufacturing industry company for example. We planned to construct the e-Catalog System, analyze the products of the company as well as design e-Catalog system using ebXML to connect EC with ERPs.

Rapid development of computer and telecommunication technology brought out the expansion of electronic commerce which is the new type of business transaction. Offline transaction can lead to problems and disputes the same is for cyberspace transactions. However ADR is not meet for the online transaction for speed, cost and open network system, ODR methods to resolve electronic commerce conflicts is crucial for building confidence and permitting access to justice in an online business environment. And ADR refers to processes other than judicial determination in which an impartial person assists those in a dispute to resolve the issues between them. ODR refers to ADR processes assisted by information technology, particularly the internet. ODR has been available since 1996. Its development can be as passing through three broad stages : hobbyist, experimental, entrepreneurial, institutional phrase. Also, ODR has adapted a range of traditional ADR for use online, including arbitration. mediation. facilitated negotiation and case appraisal. Mediation and arbitration have been the most prevalent forms of ODR. ODR is the burgeoning field and has created a new issues. All such issues which have been debated in the ADR are composed with ODR. But these are not limited. Some of issues are further complicated by the nature of the online environment such as confidentiality and principle of parties. Finally electronic commerce now takes place on the Internet, it is inevitable that the commercial world wants access to dispute resolution process that best suits the new commercial environment. ODR methods are processing for development and legal issues are considered by both national and international authorities.

With the rapid development of electronic commerce, online reputation management systems are of increasing importance in building trust and managing risk. Reputation rating mode and aggregating method are the most crucial parts of a reputation management system. In this paper, we analyze the merits and disadvantages associated with the rating mode and aggregating approach of current reputation management systems, and put forward some suggestions. These suggestions are helpful in improving current reputation management systems and developing new reputation management systems.

The generalization of Internet use has been spreaded all over the world and impacted company to introduce intranet and extranet for their operation which dealt with electronic commerce. For these reason, endeavor of implementation of web site system is promotioned and enhanced the possibility of adaptation range for the view of company. Dramatic competition which company faced with the use of internet and request from all over the world made company brought company to various and different type of level. It is necessary to develop website system with experty knowledge to satisfy customer needs. To deal with this situation, works from the level of government should proposed to spread whole country business which propelled through kyungnam mechanic industry information promotion center. With strategic proposal concerning district characteristics to adapt electronic commerce successfully, information promotion should performed. Support of government is needed continuously to realize infra of ASP composed of 4,877 mechanic industry company. It might be possible to deal with international rapid change with cooperation of company and government related department.

Now that the e-commerce users are explosively increasing, there is always followed by a sharp increase in load from the e-commerce system and the heavy traffic on the network, where leads to the delayed service for the client's request. The natural consequences contain decreasing customer satisfaction and weakening the business's competitive position in markets. Therefore, we'll need to study the e-commerce system in due consideration of the operational efficiency and response speed. This study includes a design of e-commerce system, with a hierarchical structure based on the local server, which has the capability of caching necessary to distribute the system load, makes a proposal concerning a split web-cache algorithm devoted to the local web server to finally give an analysis of the performance through the appropriate trial.

The purpose of this paper is to examine whether the international electronic payment system through IDENTRUS can be active in the future or not. For this purpose, we have reviewed the various aspects of the typical systems : their types, operational mechanisms and actual limitations in real trade. Then we have proceeded to examine the distinguished features of IDENTRUS in terms of operational procedures and characteristics by comparing to other systems. Specially as the preconditions of activation, the possibilities of cost down, time reduction, risk hedging and operational efficiency have been studied. Thus we are not sure that the IDENTRUS will have a position as a main stream in the future electronic payment system, but this system would contribute positively to the establishment of electronic payment system if some functional additions will follow.

Recently, payment method is one of the most hot issues for transaction of contents in mobile and internet markets. Many kinds of mobile contents services are rapidly growing with the combination of internet application services. Payment method algorithms are demanded for the stable transaction between producer and consumer. Security protocol algorithms are widely adapted for mobile Platform terminals. In this Paper, we described security mechanism for the current wireless internet services and compared with the performance result. There are security protocols that based on java machine platform or WAP protocols. The system is based on J2ME technology for the java mobile platform. Based on this technology, a security system is proposed for the service of mobile commerce electronic payment. The system is designed for the stability of transaction so that it enables to apply into many kinds of internet payment system.

We present a matrix-based inference alorithm suitable for electronic commerce applications. For this purpose, an Extended AND-OR Graph (EAOG) was developed with the intention that fast inference process is enabled within the electronic commerce situations. The proposed EAOG inference mechanism has the following three characteristics. 1. Real-time inference: The EAOG inference mechanism is suitable for the real-time inference because its computational mechanism is based on matric computation.2. Matrix operation: All the subjective knowledge is delineated in a matrix form, so that inference process can proceed based on the matrix operation which is computationally efficient.3. Bi-directional inference: Traditional inference method of expert systems is based on either forward chaining or backward chaining which is mutually exclusive in terms of logical process and exclusive in terms of logical process and computational efficiency. However, the proposed EAOG inference mechanism is generically bi-directional without loss of both speed and efficiency. We have proved the validity of our approach with several propositions and an illustrative EC example.
