The 21st century is witnessing the explosive increase in the usage of internet and international electronic transactions. Due to the unique characteristics of the electronic information, substantial part of such transaction can and do take the form of cross-border transactions. However, there have not been settled appropriate set of rules applicable to the international electronic transactions. Currently, in respect to e-L/C transactions in international trade, there are laws such as Electronic Transaction Basic Act in our country, E-Trade Promotion Act, E-Signature Law, Act on Promotion of Information and Communication Network Utilization and Information Protection and Marine Charter 5 in the Commercial Law. Nevertheless, a complete legislation, that is a uniform rule for e L/C which could support e L/C transactions fully hasn't been established yet. Accordingly, those laws concerned need to improve to regulate e-L/C transactions. The purpose of this paper is to look into the national status for law readjustment to prepare for a new electronic environment and to use appropriately the e-L/C issued by electronic means, and to conduct a comparative analysis on the related regulations to introduce a pertinent laws and propose related regulations to contribute to the making of effective laws to regulate e-L/C.

In the era of big data, the growth of e-commerce transactions brings forth both opportunities and risks, including the threat of data theft and fraud. To address these challenges, an automated real-time fraud detection system leveraging machine learning was developed. Four algorithms (Decision Tree, Naïve Bayes, XGBoost, and Neural Network) underwent comparison using a dataset from a clothing website that encompassed both legitimate and fraudulent transactions. The dataset exhibited an imbalance, with 9.3% representing fraud and 90.07% legitimate transactions. Performance evaluation metrics, including Recall, Precision, F1 Score, and AUC ROC, were employed to assess the effectiveness of each algorithm. XGBoost emerged as the top-performing model, achieving an impressive accuracy score of 95.85%. The proposed system proves to be a robust defense mechanism against fraudulent activities in e-commerce, thereby enhancing security and instilling trust in online transactions.

This paper presents the business model and system functionalities of a B2B e-marketplace solution that not only can overcome some problems of the public e-marketplace, but also can be applicable to both public and private types of e-marketplaces. This solution is different from the most of the public e-marketplace solutions that their main sources of revenue are transaction commissions or transaction fees through the third-party intermediation. Instead, this solution provides an ASP (Application Service Provider) functionality for direct, disintermediated purchasing and sales-related transactions between suppliers and buyers. With this functionality, suppliers and buyers electronically commerce with each other without the disclosure of their transactions as well as transaction commissions.

Compact E-cash is the first scheme which can withdraw 2^l coins within 𝒪(1) operations and then store them in 𝒪(𝑙) bits. Because of its high efficiency, a lot of research has been carried out on its basis, but no previous research pay attention to the privacy of payees and in some cases, payees have the same privacy requirement as payers. We propose a double-blind compact E-cash scheme, which means that both the payer and the payee can keep anonymous while spending. In our scheme, the payer and the bank cannot determine whether the payees of two different transactions are the same one and connect the payee with transactions related to him, in this way, the privacy of the payee is protected. And our protocols disconnect the received coin from previous transaction, then, the coin can be transferred into an unspent coin which belongs to the payee. The proposed e-cash scheme is secure within y-DDHI and LRSW assumption.

An electronic receipt (e-receipt) is a receipt issued electronically in place of a traditional paper receipt. This e-receipt, which can be accessed on a smartphone or online, allows for the exchange of goods, refunds, and other services without a paper receipt. The government is focusing on widespread dissemination of e-receipts to realize a society without paper by 2020. Introduction of the e-receipt has begun in mainly large marts and coffee shops, and recently, major franchise convenience stores. As a result, individual customer's transactions are being converted into electronic transactions, and the payment methods are changing to card-based electronic payment services or prepaid electronic payment services. The number of non-paper commercial transactions are also on the increase. In this paper, we try to identify the e-receipt industry ecosystem by analyzing the industries and markets participating in the process of receipt issuance from the perspectives of storage, management and disposal, and to analyze the domestic industrial and social economic effects expected from the spread of electronic receipts.

Challenges brought by applications of advanced technologies in education call for new approaches that can best ensure the provision of quality e-learning experiences. This paper presents an ecological approach as one of such approaches to quality assurance in e-learning that can monitor, assess and improve the effectiveness and the links between the various elements of e-learning. The ecological model for QA in e-learning emphasizes interrelation transactions between elements (e.g. providers, learners, cultures and policies) and systemic integration of those elements, and stresses that all these elements within a QA system play an equal role in maintaining balance of the whole. The model focuses attention both on individual and societal/cultural environmental factors as cornerstones for QA efforts in e-learning. It addresses the importance of QA efforts directed at changing QA transactions from provider-centered to 'all stakeholder-oriented', from one-size-fits-all model to 'globally oriented, locally adaptive model' and from control framework to 'culture creation framework'.

The explosive growth of e-marketplace transactions requires an appropriate trust measuring framework to protect involving transacting entities such as buyers and sellers. As a strategic competitive edge, e-marketplace service providers have been adopting various system features that make sure no one transacting entity takes a major risk in online transactions involved. In this paper, an improved trust measuring method using fuzzy theory for an e-marketplace is proposed. The proposed methodology incorporates fuzzy set and calculation concepts to help build trust matrices and models, which are used to measure the level of risk involved in a specific e-marketplace transaction concerned. The proposed framework can be utilized to optimize the transaction costs by recommending a differentiated transaction process according to the risk level involved in each online transaction.
