Electronic Commerce has already existed for over 20 years. The Bolero project initially had the support of TEDIS, and now is jointly financed by SWIFT(Society for World International Financial Telecommunications) which handles most of the electronic funds transfer for banks, and the Through Transport Mutual Assurance Association(the TT Club), a mutual insurance association most of whose members are drawn from the Multimodal transport industry or transport intermediaries. Bolero's mission is to provide guaranteed and secure delivery, in electronic form, of trade documentation, globally, based on a binding legal environment and common procedures, Bolero will also provide a platform for provision of neutral cross-industry services. TradeCard is a payment and settlement system that is an alternative to letters of credit. That is, TradeCard is a business-to-business e-commerce infrastructure that enables buyers and sellers to conduct and settle international trade transactions securely over the Internet. Paperless, payment-guaranteed international trade transactions - which eliminate the traditional letters of credit with electronic certifications - are widely considered the most difficult B2B transactions to conduct.

With a great improvement of computers and Network communication skills, we can exchange information quickly. There have been many researches on the subject how to guarantee the information security by security mechanism and cryptography schemes. Nowadays, many people in this area show their interest in money transfer systems between accounts, which can provide a secure mechanism in which people can send money to the legitimate party or person safe. However, we have teamed many ways to distort messages and repudiate the malicious activity in mail systems based on SSL mechanism. It is very likely that important information which must be kept in secret is laid exposed to un_authorized user. Accordingly, to provide stronger security service, researches on electronic payment system which tan guarantee the security characteristics such as confidentiality, integrity, user authentication, Non-repudiation, are strongly needed. In this paper, we analize the characteristics of the previous researches in this field, and also propose a securer electronic payment system based on ECC algorithm.

인터넷은 컴퓨터와 네트워크의 가상공간을 통하여 그 개방성과 뛰어난 확장성으로 전자상거래의 기본수단이 되고 있으며 경이로운 발전을 거듭하고 있다. 이에 따라 현재 전세계는 전자상거래가 폭발적으로 성장하는 시기를 맞이하고 있다. 일본에서도 최근 일본정부가 2005년까지 초고속인터넷을 3000만 가구에 보급할 계획을 세우고 있는 등 인터넷의 고속화가 빠르게 진전되고 있고, 이용자의 인터넷 접속요금도 저가격화로 변화함에 따라 전자상거래 이용지도 급속도로 증가할 것으로 예상된다. 그리고 TV를 이용한 게임기나 인터넷 전용머신이라는 컴퓨터 이외의 디지털기기로 인터넷을 이용하는 등 전자상거래 이용수단도 다양화될 것이며, 또한 디지털 텔레비전과의 제휴를 통하여 디지털데이터방송을 활용한 전자상거래도 활발히 이루어질 전망이다. 이에 따라 일본의 전자상거래시장의 급속한 성장과 함께 결제수단도 다양화되고 있다. 전자상거래의 결제수단으로서는 현금, 우편환, 은행입금, 수표 외 전자상거래의 특유의 결제수단이라고 할 수 있는 전자화폐, 인터넷뱅킹, E-Debit 등이 있다. 이 가운데 전자화폐는 일반적으로 유통성, 양도가능성, 범용성, 익명성 등 현금이 가지고 있는 기능을 갖추고 있을 뿐만 아니라 원격지송금성, 수송상의 비용절감, 금액의 분할 및 통합의 유연성, 전자성 등의 특징을 갖고 있으며 현금의 단점을 보완하는 기능도 있기 때문에, 앞으로 신용카드를 대체하는 차세대 전자결제수단으로 등장할 것이 확실시된다. 따라서 본고에서는 현재 일본 내의 다양한 주체들에 의하여 개발 실험되고 있는 전자화폐에 의한 결제시스템을 개관함으로써 우리나라에서도 일본과 같은 다양한 전자화폐에 의한 결제시스템의 개발 실험 도입이 절실함을 제안하였다.

It is expected that the electronic money will be a major payment method in the forthcoming electronic finacial system. However, in order for the electronic money to have a widespread use among general public in their dialy life there are many properties that should be satisfied beforehand. In this study, we first analyze the characteristics of the existing electronic money systems, compare various proposals on the electronic money system so far, and then suggest a desirable model of developing an electronic money system for Korean financial institutions. It has been found that the model we propose satisfies the general requirements of the electronic money system. The results of this study will aid in various activities of technology development and standardization. Furthermore, this study will support the initiative effort of Korea in developing inter-country electronic money system.

Today, banks around the world are making great efforts to adapt to the rapidly changing internal and external environment changes caused by the development of IT technology and to gain a competitive advantage in the market. In particular, in line with the rapid growth of smartphone usage, financial services are also provided in a variety of ways using Fintech, and one of the fastest growing areas is mobile simple payment. Mobile payment service is a financial service that pays the purchase price using a portable mobile device. As fintech, a convergence of financial services and information technology, it is recently used not only in financial services, but also in various industries. It is used in all fields where payment functions such as distribution are available. In the case of mobile cards, it shows that the usage rate of people in their 20s and 30s is increasing very much, so it can be said that the use of mobile payment services will continue to increase in the coming future. We know that simple payments are being used. However, it can be said that the research on the use of mobile payment services by these teenagers is somewhat incomplete. Therefore, this study investigated what factors are important for Korean teenagers to use mobile payment services. As a result, among the five hypotheses presented in this study, all hypotheses were adopted except for , which states that cash usage habits have no effect on innovation.

The volume of electronic banking service via smart phone is expected to increase dramatically under smart convergence environment. Under such circumstances, the effort to establish the mobile electronic banking culture which took a major step forward from the conventional electronic commerce method is essential. It is necessary to standardize the mobile payment infrastructure in order to resolve the initiative conflicts between financial institutions and newly launched non-financial institutions. Furthermore, a domestic and international strategy is required as the number of NFC technology based smart phone transaction business is increased. As various types of business enter the electronic commerce field, efforts to resolve the dissatisfaction of the customers are critical. Additionally, security is one of the significant issue due to the conversation process to open-type operating system. This study surveyed and analyzed the current domestic and foreign status, the problems in Korea, and suggested an effective counterplan and policy, which could be helpful in governments' preparation for electronic commerce policy.

With the growth of the EC(Electronic Commerce), Buying and selling software through the internet are expanded. Among the ESD(Electronic Software Distribution) methods, Buy-first method and TrY-before-bu1 method can not solve the illegal copy problem. Recently developed EL(Electronic License) model solve the illegal copy problem by separating the software and license. But this method also can not support various ways for payment. In this paper we propose the software license management system that is a newly form like ESD model. This system proposes NL(New License) to support various payment methods and SC(Software Charge) to insure that a seller takes the software price. Agent of the proposed system offers scalability to other systems and illegal copy protection function bv managing NL and SC.
