The e-marketplace has emerged as a new place for transactions in the online industry. In the e-marketplace, buyers make transactions with whom they have little prior interaction. Thus it makes trust as one of the most important issues in the e-business. There are various kinds of information to foster customer's trust in the e-marketplace. In this study, we analyzed the impact of the information's satisfaction on the customer's transaction intention. The results showed that the satisfaction on the information related to transaction system, individual seller's information, and buyer's feedback are all positively related with the customer's transaction intention.

They agreed to decide the recipient's business presence and usual residence as the place of consumption. In the area of consumption tax, they reaffirmed the destination principle. They agreed to decide the recipient's business presence and usual residence as the place of consumption. Currently, the Korean VAT law does not have a basis for taxation on international transactions that are considered to be services. Considering the tax revenue loss and the inequality between domestic suppliers and foreign suppliers when international transactions are not taxed, the Korean Tax Authority needs to amend the current law.

Todays, L/C transactions in international trade are governed by UCP 500 and eUCP. But UCP 500 and eUCP do not cover all legal problem of L/C transactions. Therefore choice of laws in international L/C transactions are occurred. U.S.A. has an enacted law (UCC ${\S}5-Letter$ of Credit) to govern L/C transaction. But other countries has no special enacted law to govern L/C transaction. The reason is that there are difference between legal attitude of U.S.A. and other countries. American law considers L/C as a special device made by merchants. Therefore U.S.A. applies UCC ${\S}5-Letter$ of Credit instead of general contract law. UCC ${\S}5-Letter$ of Credit includes provisions of warranties, remedies, and so on that UCP 500 and eUCP do not include. But the liabilities of the Issuing Bank on the wrongful dishonor in L/C transaction is very important legal problem. First, this study is to justify concepts of honor and dishonor, and sufficient conditions for dishonor of the issuing bank. in UCC. Second, this study is to examine closely the liabilities of the Issuing Bank on the wrongful dishonor in L/C transaction. Third, this study is suggest distinctive features on the Liabilities to wrongful dishonor of the issuing bank in UCC ${\S}5-Letter$ of Credit and our trader's matters to be attended to L/C transactions governed by UCC.

Along with the development of Information Technology, online transactions through Internet have become more popular for the reasons of convenience and efficiency. In order to provide secure and reliable online transactions, an effective electronic payment protocol is crucial. In this paper, we propose a novel electronic payment protocol for digital product transactions with an offline arbiter to achieve fair exchange, automated dispute resolution, customer anonymity, and customer unlinkability. In our protocol a product token is adopted to eliminate the need of key management for digital product decryption in the offline arbiter. In addition, Elliptic Curve Cryptography (ECC)-based self-certified public key is utilized to further reduce computing overheads. According to our analysis, the efficiency of our protocol can be greatly increased in comparison with previous literatures.

As major industries become information -centered, business transactions and information -sharing processes are being computerized and automated, which ultimately re-defines electronic commercial transactions in a broader context. Business documents are the basic tools for corporate transactions. The use of business documents in electronic commercial transactions has increased markedly and this sphere is rapidly being extended to include information sharing between companies. XML(extensible Markup Language) was selected as the focus for this thesis. XML can help to make a complicated and data-rich document easy to share. The thesis proposes a business XML document editing system, comprised of a style document editor for business XM document structure, business documentation, and business document presentation, along with a business document transformation system which makes a transformation possible regardless of platform or using various corporate document standards.

By e-Financial Transactions Act enacted in January 2007, the financial institutions are responsible for indemnifying user's damage to ensuring security of the electronic financial transactions and to protecting financial users when suffering from electronic financial accidents. However, when occurring unauthorized financial transactions or electronic financial accidents by user's moral hazard, it is difficult to determine where the accidents happened at and whether caused by the intention or gross negligence of users. To protecting financial parties and ensuring the security and reliability of electronic financial transactions, this paper attempts to propose the means, what enhance the notification process about financial transactions and to strengthen IT regulatory compliance by using area information about electronic financial transactions, to protect risk of the financial accidents.

Online or e-banking has been adopted as key banking innovation in Uganda adopted by all financial institutions in the country. This research explored the state of e-banking and its efficacy in Uganda banking industry. A correlation analysis approach was adopted for this research. In Uganda, the banking sector has been liberalized with telecommunications allowed to effect e-banking and ecommerce transactions. The study concentrated on the periods of years 2011/2012 and 2012/2013. Findings from this research revealed that BOU uses UNISS for real time gross settlement (RTGS). Since its adoption a +1 coefficient correlation was realized. With the use of mobile money, also a +1 coefficient correlation was achieved for the period under consideration. As regards the use of e-cheques, there was a drop reflected by -2.8 percent which could have been attributed to perception of the users, though there was a +1 coefficient correlation when considering e-cheque transactions and the monetary value. The use of EFT in Uganda generated a +1 coefficient correction considering the number of users and the monetary value involved. Bank of Uganda should work hard and make or go live with electronic banking supervision software which would aid them with their supervisory roles.

An electronic services which are based on Internet/Intranet business transactions are available to e-market places and get the broader business concepts. Component-based e-commerce technology is a recent trend towards resolving the e-commerce chanange at both system and ap-plication levels. The basic capabilities of component based systems should include the plug and play features at various granularities, interoper-ability across networks and mobility in various networking environments. E-business application developers are attempting to more towards web-service as a mechanism for developing component-based web-applications. Traditional process and development models are inadequately architectured to meet the rapidly evolving needs for the future of scalable web services. In this thesis, we focus specifically on the issues of e-business system architecture based on web service for establishing e-business system. We specifies and identifies design pattern for applying e-business domain in the context of multiple entities. We investigate prototype and frameworks to develope components for e-business application based suggested process. We present a worked example to demonstrate the behavior of Customer Authentication System(CAS) development with component and recommend process. Final]Y, we indicate and view on future directions in component-based development in the context of electronic business.

e-Governance is a medium to offer various services to citizens through a web portal, that exists in many countries nowadays. The existing e-Governance technology is a vast, centrally managed database and a set of applications that connect to it via web interfaces. Despite the modernisation of services, it remains with the lack of transparency. Thus, the existing infrastructure of e-Governance paves the way for corrupt practises by the bureaucrats. e-Governance needs a powerful underlying technology which doesn't provide any way to allow tampering of the record and which in turn eliminates corruption. In this paper, we took land registration as a use-case for building e-Governance by keeping Blockchain as an underlying technology, to put off the corrupt practices and to bring transparency. Once transactions in land registration added to the Blockchain, it is immutable as it is cryptographically secured. Besides, the blockchain technology is secured as the ledger is distributed over the network. If a hacker wants to modify the ledger, he needs to hack every node in the blockchain network. Hyperledger Fabric, a permissioned Blockchain adopted for implementation and Hyperledger Caliper for performance analysis with these evaluation metrics such as throughput, latency and execution time.
