Human cognition and decision-making related to information systems (IS) is a major area of interest in IS research. Among these areas, cognitive bias rooted in behavioral economics is gaining considerable attention from researchers. In the present study, we identify the role of cognitive biases and discuss how they shape the information security behavior. We also seek research opportunities to provide directions and implications for future research.

전통적인 전자상거래방식에서는 정보를 교환할 경우 종이서류에 의한 방법이나 폐쇄형 EDI에 의한 정보교환으로 심각한 문제점은 없었다. 점차 인터넷의 발달로 전자상거래의 규모는 더 커지고 온라인 전자상거래로 변화면서 신원확인, 정보의 변조, 당사자 간의 부인 방지 등 많은 문제점이 발생하였다. 이런 문제점으로 인행 분쟁을 예방하고 사후처리를 위해 전자상거래의 모든 단계에서는 보안 기술을 활용하고 이를 관리하는 인증이 개입하고 있다. 하지만 최근의 모바일 지급결제 서비스 중심으로 핀테크 열풍이 거세게 불고 있다. 카드사 정보유출 사고 및 해킹 등으로 금융서비스의 안정성 확보에 부족하다. 핀테크 산업의 발전과 진화는 정보보호와 동반 성장해야 한다. 따라서 해외의 유명 핀테크 기업의 정보보안체계를 살펴보고 국내 핀테크 기업이 나야가야 할 방향을 제시하고자 한다.

본 논문에서는 안전한 전자상거래를 위해 가상카드번호 생성시스템에 대한 연구를 진행하였다. 통신망 보안의 필요성이 급격히 증가하고 있는 추세에 맞추어, 전자상거래의 양 및 질적 팽창에 따른 안전한 상거래의 필요성도 더욱 증가하고 있다. 실제카드번호를 네트워크상에 노출시키는 대신 가상카드번호를 생성하여 노출시킴으로써 해킹의 위험을 원천적으로 차단할 수가 있다. 다양한 실험을 통하여 이를 증명하였다.

To enhance customer satisfaction for higher profits, an e-commerce sector can establish a continuous relationship and acquire new customers. Utilize machine-learning models to analyse their customer's behavioural evidence to produce their competitive advantage to the e-commerce platform by helping to improve overall satisfaction. These models will forecast customers who will churn and churn causes. Forecasts are used to build unique business strategies and services offers. This work is intended to develop a machine-learning model that can accurately forecast retainable customers of the entire e-commerce customer data. Developing predictive models classifying different imbalanced data effectively is a major challenge in collected data and machine learning algorithms. Build a machine learning model for solving class imbalance and forecast customers. The satisfaction accuracy is used for this research as evaluation metrics. This paper aims to enable to evaluate the use of different machine learning models utilized to forecast satisfaction. For this research paper are selected three analytical methods come from various classifications of learning. Classifier Selection, the efficiency of various classifiers like Random Forest, Logistic Regression, SVM, and Gradient Boosting Algorithm. Models have been used for a dataset of 8000 records of e-commerce websites and apps. Results indicate the best accuracy in determining satisfaction class with both gradient-boosting algorithm classifications. The results showed maximum accuracy compared to other algorithms, including Gradient Boosting Algorithm, Support Vector Machine Algorithm, Random Forest Algorithm, and logistic regression Algorithm. The best model developed for this paper to forecast satisfaction customers and accuracy achieve 88 %.

최근 XML 문서는 전자상거래 분야에서 표준 전자문서로 자리매김을 하고 있다. 표준화된 전자문서의 정보보호 서비스는 전자상거래의 활성화에 큰 걸림돌로 작용하고 있으며, 안전한 전자상거래를 위해서는 우선적으로 전자문서에 대한 정보보호 서비스 기능을 제공해야만 한다. ESES(ETRI Secure E-commerce Services)는 전자상거래 시 교환되는 XML(extensible Markup Language) 전자문서 및 기존의 일반 전자문서에 대한 정보보호 서비스를 제공하기 위한 시스템이며, 전자상거래 플랫폼에 절대적으로 필요한 시스템이다. 본고에서는 ESES 시스템의 구조출 제시하며, XML 기반 전자상거래에서의 전자 문서 교환 시 인증, 무결성, 비밀성 등을 지원할 수 있는 안전한 전자상거래 플랫폼을 설계한 내용을 기술한다.

People have transferred their business model from traditional commerce to e-commerce in recent decades. Both shopping and payment can be completed through the Internet and bring convenience to consumers and business opportunities to industry. These trade techniques are mostly set up based on the Secure Sockets Layer (SSL). SSL provides the security for transaction information and is easy to set up, which makes it is widely accepted by individuals. Although attackers cannot obtain the real content even when the transferred information is intercepted, still there is risk for online trade. For example, it is impossible to prevent credit card information from being stolen by virtual merchant. Therefore, we propose a new mechanism to solve such security problem. We make use of the disposable dynamic security code (DSC) to replace traditional card security code. So even attackers get DSC for that round of transaction, they cannot use it for the next time. Besides, we apply visual secret sharing techniques to transfer the DSC, so that interceptors cannot retrieve the real DSC even for one round of trade. This way, we can improve security of credit card transaction and reliability of online business. The experiments results validate the applicability and efficiency of the proposed mechanism.

The trend of satisfying consumer needs (payment for mobile communication, music services, cab ordering, banking products, and food delivery) on a unified online platform has shaped a digital ecosystem, an instrument creating a unified space of economic interaction. Representatives of e-commerce are major stakeholders in the development of such tools. In particular, subscription services (multiservice subscriptions) allow users to create their own ecosystems based on their personal preferences. The rate of subscription service use is growing around the world, yet understanding of the peculiarities of development of this e-commerce sphere is limited due to insufficient research.The study aims to determine the motives and barriers to the use of subscription services (multiservice subscriptions) by consumers and their relationship with consumer characteristics.Proceeding from an online survey of 200 users, the study determines the relationship between the gender and income of consumers and their use of subscription services, motives and motivators for using subscription services, and barriers to the choice of a particular subscription service. The obtained results may serve as a basis for managerial decisions in e-commerce and for improving the effectiveness of marketing solutions.

This study deals with controversial issues surrounding the today′s cyber-taxation and recommends feasible consumption tax system architecture titled Global Electronic Tax Invoice System (GETI). The GETI is an electronic consumption tax architecture to provide "all-in-one" tax and e-payment services through a trusted third party (TTP). GETI is designed to streamline the overall cyber-taxation process and provide simplified and transparent tax invoice services through an authorized np. To ensure information security, GETI incorporates public Key infrastructure (PKI) based digital certificates and other data encryption schemes when calculating, reporting, paying, and auditing tax in the electronic commerce environment. GETI is based on the OECD cyber-taxation agreement that was reached in January 2001, which established the taxation model for B2B and B2C electronic commerce transactions. For the value added tax systems, tax invoice is indispensable to commerce activities, since they provide documentations to prove the validity of commercial transactions. As paper-based tax invoice systems are gradually phased out and are replaced with electronic tax invoice systems, there is an increasing need to develop a reliable, efficient, transparent, and secured cyber-taxation architecture. To design such architecture, several desirable system attributes were considered -- reliability, efficiency, transparency, and security. GETI was developed with these system attributes in mind.
