M-Commerce에서 안전한 데이터 서비스를 위해서는 정보보호 및 무선 결제 시스템에 대한 연구가 반드시 선결되어야 한다. 현재 무선 결제 서비스는 이동통신사를 중심으로 한 소액결제 서비스가 주를 이루고 있으며, 신용카드 기반의 결제 서비스는 고액결제가 가능하지만 무선 결제 시스템에 취약한 문제점을 가지고 있다. 본 논문에서는 지불 승인 절차에 병목 현상을 개선하기 위해 일회성 패스워드 시스템을 적용한 PDA 기반 모바일 고액결제 시스템을 제안한다.

Untact marketing emerged as one of the top 10 marketing in 2018. Since then, the scale of the mobile payment market has expanded, and the ratio of payment through mobile is melting into life even offline. Various mobile apps such as Samsung Pay and Smart Order are already popular systems, and various other mobile payment systems are increasing. For such mobile payments, this paper aims to comprehensively design a general-purpose untouched offline payment system by designing a mobile payment system that applies a short-range wireless communication method along with a study on the currently available mobile payment-linked API. We propose an offline payment system with an untouch method to prevent the spread of infectious diseases and contribute to a healthy society by solving the problem and minimizing contact with others in the current situation like the Corona 19 Incident.

신용카드를 이용한 결제가 증가하고, 카드 사용 건수가 증가하면서 신용카드의 사용이 대중화 되었다. 그에 따라 모든 거래에서 카드 결제 요구가 증가하고 있지만, 기존의 무선 카드 결제기는 고가이고, 현장에서 사용하기 불편하여 사용분야가 제한되고 있다. 특히 운송/운수 및 방문판매업 분야와 같이 현장에서 카드 결제를 직접 수행하여야 하는 경우에는 기존의 카드결제기를 사용하는데 있어 여러 가지 문제점들이 있어왔다. 본 논문에서는 사용자가 일상적으로 사용하는 휴대폰 등의 모바일 단말과 연동하여 카드 결제가 가능하도록 하는 휴대형 모바일 카드 리더기와 이를 이용한 유비쿼터스 카드 결제 시스템을 제안한다. 개발된 시스템은 항시 휴대하는 휴대폰과 연동하여 사용이 가능하므로 언제 어디서나 카드결제가 가능하도록 하는 특징이 있다.

This study is about finding factors affecting user experience in China's mobile payment. The recen development of 5G networks and the spread of phones provide the basis for the development of mobile payment, and the development of mobile payment is showing a rapid upward trend. Because of the simplicity and mobility, it is appealing to people, especially young people. Therefore, this study conducted a survey on mobile payment users in 20s and 30s and confirmed the factors affecting the user experience through regression analysis. Unlike previous studies on mobile payment technology, this study focused on user experience and identified factors affecting user experience, so it is expected to be helpful in the development of mobile payment in China.

Recently, smart devices for various services have been developed using converged telecommunications, and the markets for near field communication (NFC) mobile services is expected to grow rapidly. In particular, the realization of mobile NFC payment services is expected to go commercial, and it is widely attracting attention both on a domestic and global level. However, this realization would increase privacy infringement, as personal information is extensively used in the NFC technology. One example of such privacy infringement would be the case of the Google wallet service. In this paper, we propose an mutual authentication scheme based on NTRU for secure channel in OTA and an zero-knowledge proof scheme NTRU based on for protecting user information in NFC mobile payment systems without directly using private financial information of the user.

Thanks to popularization of smart phone, mobile payment market is growing rapidly. As the obligatory use of digital certificate is abolished, easy-to-use payment that can settle with only password is being launched one after another. But its spreading speed is not fast highly. Because of concern about personal information leakage and security, unchangeability of payment habit, insufficiency of consumer protection, inadequacy of payment infrastructure and all sorts of regulations, easy-to-use payment is not activated. Recently global IT companys are entering mobile payment market competitively. It is because the sense of crisis that their survival can be dangerous from now on if they get left behind Fintech innovation and the mentality that they try to take the leadership of mobile payment market process. In this situation, the thorough preparation and a lot of effort are required to promote our autonomous easy-to-use payment growth without dependance on foreign country's. In this paper, the problems of local mobile easy-to-use payment are addressed in depth and the activation measures such as flexible and discriminative security, construction of customer protection system, law system maintenance, service differentiation are proposed.

As increasing of smartphone penetration over the world, various mobile payment services have been emerged and fraud transactions have drastically increased. Although many financial companies have deployed security solutions to detect fraud transactions in on/off-line environment, mobile payment services still lack fraud detection solutions and researches. The mobile payment is mainly comprised of micro-payments and payment environment is different from other payments, so mobile-specialized fraud detection is needed. In this paper, we propose a FDS (Fraud Detection System) based on data mining for mobile payment services. The method of this paper is applied to the real data provided by a PG (Payment Gateway) company in Korea. The proposed FDS consists of two phases; (1) the first phase is focused on classifying transactions at high speed (2) the second is designed to detect abnormal transactions with high accuracy. We could detect 13 transactions per second with 93% accuracy rate.
