The B2B e-commerce assurance system supports e-commerce purchases by Credit Guarantee Fund. This process seeks to replace a variety of current systems, including B2C, the credit card payment method on B2B, 2001 Credit Guarantee Fund and the Bank, logistics, e-MP (Market Place), and Business-to-business e-MP (business-to-business electronic payment settlement system). Over the past 10 years of its operation, the e-MP service (B2B e-commerce electronic payment systems) has contributed much to the growth of SMEs. The development of business-to-business e-commerce transactions systems and limits have provided a stable purchasing platform, improving corporate competitiveness. However. the project-based scale of credit guarantee institutions has limitations. To overcome these limitations, we propose a new model of direct or indirect government support for small business e-MP projects. This new model will support the B2B electronic commerce by allowing it to directly involve guarantee institutions directly in B2B online transactions. Therefore, this study urges government backing of the SME based B2B online business model with e-MP service.

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.

Traditionally banks and other financial institutions use customers' accounts and information managed by them and provide payment services in dominant positions. Recently, EU amends Payment Services Directive to institutionally guarantee access to customers' accounts and use of account-related information even to third parties, which facilitates competition in financial markets and promotes innovation. However, this kind of change can increase potential security risks and therefore institutional responses from financial authorities are required so that all participants in financial markets can properly respond to security risks. In this study institutional responses to the security risks in the EU's new Payment Services Directive (PSD2) are analyzed, comparisons between this and domestic electronic financial regulations are analyzed, and implications for the direction of improving domestic electronic financial regulations will be suggested.

Various construction bonds and warranties critically burden the general contractor. Also, sporadic or cumulative delays of progress payment by the owner can further trap the contractor in a financial quagmire. Facing the possibility of cash flow deficiency and callous response from the banks, most construction firms may become financially incapable of market competition, and attractive project tenders become a bidding game among few deep-pocket players. The downside of such market environment is that the depth of pocket, rather than that of professional competency dictates the choice of market winners. In Taiwan, this has been a potential crisis to the construction industry after the financial crisis which started out since 2008. To encounter this problem, this research will examine the means to better manage the construction industry. Essentially, a credit guarantee system (CGS) is the prime solution to strengthen a bank's confidence in any particular construction firm. Thus establishing a national platform which evaluates and rewards a construction firm's overall credibility is pivotal, and this third-party rated credit can help a bank to render a loan more wisely. Finally, this paper will propose the ideal operating schemes of construction-specific CGS in Taiwan and a credit scoring prototype model for construction industry, as reference for the government and banks, respectively.

B2B e-commerce guarantee service is a guarantee service combining the electronic systems among Korea Credit Guarantee Fund(KCGF), banks and e-marketplaces to process all procedures on internet ranging from application for credit guarantee, issue of written guarantee and contracting for a commerce to payment. B2B e-commerce guarantee service plays as an intermediary role in financial support for small and mediumsized enterprise(SME), which are small size, low credit level, and unfavorable status in many aspects compared to major companies. Despite the B2B e-commerce guarantee service has various advantages conducive to promotion of e-commerce among small and medium businesses as well as development of e-commerce itself, it has yet to be diffused due to lack of acknowledgement, misunderstanding of its functions and vague psychological fear of the on-line settlement. Thus, this study identifies the values and effects of the B2B e-commerce guarantee service using financial data and cases. The process of this study is 4 phase. first phase is analysis of B2B e-commerce guarantee service and e-Marketplace. second phase is analysis of performance from the Perspective of Diverse Participants. third phase is analysis of economic performance and support for SME. last phase is policy suggestions and conclusion.

This research suggests for efficient operation of the e-commerce guarantee financing system in domestic industries by reviewing the definition, current situation and problems of the e-commerce guarantee financing system in operation since 2001. Throughout the 10 years of the e-commerce guarantee financing system's implementation, technological development has solved many previously concerning factors. The goal of the study is to resolve the current issues of the e-commerce guarantee financing system and offer means by which to expand the accessibility of the system to domestic industries and further assistance to firms already using the system. One of the primary policies supported by the research is the reallocation of funds from archaic means of exchanging finances to the modem e-commerce guaranteed financing methods because of the increased transparency of the trading. Specifically, the funding operated by government guarantee agencies requires systematic promotion, justifying subsidies and tax breaks to companies that are using e-commerce guarantee financing because of the increased overall transparency. In addition, the benefits of e-commerce guarantee financing as a means of funding are numerous: the promotion of good business, relaxation of credit ratings for company loans, construction of the mobile operating system for small businesses, and creation of policy flexibility in operating fund agencies run by government. Future research areas include continued collection and analysis of the above data provided and new market feedback such as direct poll surveys of the operating staff in companies using e-commerce guarantee financing agencies.

To accommodate the rapid growth of e-commerce transactions, non-face-to-face transactions, businesses use a wide variety of payment methods. However, many of these payment mediums are not secure as shown by increases in fraudulent transactions. In this paper, we analyze a particular e-commerce transaction medium, the Safety Transaction Service (STS). This system protects consumers through a wide variety of safeguards: safety settlement systems (escrow), consumer damage compensation insurance, payment guarantee, and secure bank settlement. In contrast to the safeguards, we identify the limitations and concerns with the STS and potential legal and political improvements. The plethora of payment methods limits the consumers ability to distinguish between the secured and unsecured transaction services. Regulation and consumer based verification of transaction services are essential to root out dangerously fraudulent systems. We propose the development of specific standards to these systems, in particular the need for consumer confirmation and clear settlement documentation. Only through the active promotion of scrutiny and improvement to STS will consumers be protected in e-commerce.

Verifiable encryption is an encryption technique with which one can verify what has been encrypted even if one can not decrypt the ciphertext. This technique can be used in fair exchange to convince the counterpart of his or her receiving an item by presenting an encrypted form in advance. In this paper, a method that can guarantee the payment atomicity is proposed by applying verifiable encryption to an electronic cash system based on the representation problem. With the new method, the process of dispute settlement is improved in the fact that the trusted third party do not have to interact with the bank to resolve disputes. This method is also flexible in a sense that clients and shops can request for dispute settlement regardless of any deadline constraint. However, additional proof is necessary to apply verifiable encryption during payment. We discuss the security and the atomicity of our method, and compare ours with others.
