이동단말기의 보급률이 높아짐에 따라 이를 이용한 지불 시스템이 제시되었고, 현재 서비스를 제공중에 있다. 이동 단말기를 이용한 지불 시스템은 폭넓은 이동통신 보급률, 편리함, 간편함, 후불결제와 같은 장점들을 가지고 있다. 그러나 사용자는 서비스 제공자가 신뢰할 수 있는 서비스/물품 제 공자인지 알 수 없다는 단점을 가지고 있다 본 문에서는 이러한 단점을 극복하기 위해서 Diffie-Hellman 키 합의 프로토콜을 이용하여 상호 인중을 보장하는 지불 시스템을 제안한다.

This study uses S-O-R framework to examine the relationships among consumers' perception of economic benefits, usefulness, privacy risks, switching cost, and emotions and continued intention usage. Results from an online survey of 324 qualified respondents were analyzed using the structural equation model. The results of the survey showed that first, perceived economic benefits and perceived usefulness has a positively effect on consumers' positive emotions. Second, perceived privacy risks have a negative effect on consumers' positive emotions. Third, perceived usefulness has a negative effect on consumers' negative emotions. Fourth, perceived switching cost has a positive effect on consumers' negative emotions. Fifth, consumers' positive and negative emotions have an effect on continuous usage intention. Sixth, consumers' positive and negative emotions have a mediating effect. The S-O-R model can explain consumer's continued intention to use mobile payment services. The study analyzed the emotional elements of mobile payment services. Emotional elements through mobile payment services can be applied to other financial services. Therefore, this study can guide emotional related practices with various future consumer electronic services.

In the era of convergence, more attention is paid to development of Fintech which attempts for innovation of the financial transaction paradigm through ICT. Proliferation of Fintech to engraft finance-related services on mobile and ICT is found in various fields such as loans, investment and asset management in addition to simple payment or remittance services but awareness of consumers regarding the matter is rather low. Therefore, it is the time to conduct a research on various Fintech businesses. This thesis conducted an empirical research from the viewpoint of consumers to investigate influence on continuous use intention of Fintech users. From the user environment perspective, it was found that influence of innovativeness on satisfaction was not statistically significant. In case of the product characteristics, perceived risk did not have statistical significance on satisfaction.

In the newly encountered economy caused by the Corona virus Disease-19, remote transaction becomes a new normal that disrupt traditional economic order. In the middle of the disruption, mobile tech is placed and remote finance on mobile is highly noticed and considered as an infra-tech to support the new ecology, In mobile finance. remote payment is becoming the most common service and personal identification on it is critical to operate the new service. There are various means of remotely identifying a person. Recently the use of biometric information is increasing. In this study, a correlation analysis was conducted on factors that effects to biometrics usage and the intention to use in remote personal identification. Variables for critical factor in the remote identification were classified into 4 groups such as Performance expectancy, Effort expectancy, Social influence, and Security. The empirical analysis based on the Unified Theory of Acceptance and Use of Technology (UTAUT) was conducted. The relationship between variables and the intention to use is also analyzed. In the study, stepwise regression analysis was conducted four times in which variables were adjusted in individual stage. As a result, the analysis suggests that performance expectancy, effort expectancy, social influence, security have positive effects for intention to use. Additionally, effort expectancy and security have moderating effects to intention to use depends on biometric authentication experience. The analysis has shown positive effect of variables grouped on the intention to use them. It also suggests that the intention to use biometric authentication will quickly grow. This study is expected to make a contribution to utilize and improve the use of biometric information in mobile payment.

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.

핀테크는 국제적으로 매우 각광을 받고 있는 산업이다. 이러한 동향에 편승하여 국제표준화에서도 많은 관심을 보이고 있다. 기술 개발을 통하여 핀테크로 구축된 정보를 공개적으로 사용이 가능하며, 이를 기반으로 새로운 산업 창출이 가능하기 때문이다. 간편결제와 같이 사용자의 편의성을 제공하는 전위적(Front-end)인 역할도 있지만, 서버의 정보를 폐쇄적으로 관리 하던 것을 핀테크 기술을 이용하여 공개되고, 사용자 및 스타트업들이 공개된 정보를 통하여 새로운 융합정보, 나아가 융합 서비스를 창출하는 후위적 역할도 있다. 핀테크 산업의 기반기술이 공개소프트웨어로 제공되고 있으며, 이를 이용하여 빠른 발전을 하고 있으나, 공개성으로 인하여 취약점 마저도 공개되어 정보보안의 위협으로 작용되므로 오픈 플랫폼의 정보보안을 중심으로 핀테크 정보보안 기술동향과 표준의 방향을 살펴본다.

The main channels of the financial industry are rapidly changing to mobile. In this environment, banks are focusing on information and communication technology to secure their competitiveness, and rapid innovation is being pursued especially in the payment settlement sector. In October 2019, Korea also introduced open banking services to accelerate the financial innovation, such as the open conversion of financial settlement networks and the expansion of the use of simple payments. In this paper, an empirical study was conducted on the effect of domestic open banking quality factors on usage intention. The service quality factors for open banking were classified into interface design, innovation, security, and data sharing, and the technology acceptance model (TAM) was used to verify whether it has a significant effect on perceived convenience, usefulness and intention to use. According to the analysis results, while innovation and security did not have a significant effect on convenience and usefulness, interface design and data sharing were found to have an effect on perceived convenience. The results would provide implications for some quality issues for companies seeking to introduce open banking services as well as for the related academic arena.

As financial deregulation policies implemented by the government, electronic financial service is improved but security concerns are increasing and ultimately weaken trust in the financial service. Electronic financial service becomes more and more dependant on the IT platform and the initiatives of access device is also gradually shift to that platform. As biometric sensor is mounted on the smartphone, structural change in the access device is coming. It must be a positive signs in terms of fintech development, in the other side, it can cause many problems such as weakness of regulation and ambiguity of principals of responsibility. So in this paper, by analysing this problem-the shift of service initiative-on the access device I'll propose the best way to the the legal amendments.

최근에는 많은 스마트폰 어플리케이션이 결제와 할인쿠폰, 적립 등 각종 기능을 제공하면서 사용자들에게 매우 간편한 거래 방식을 제공할 수 있는 NFC 서비스 시장이 성장할 것으로 전망되고 있다. 특히 스마트폰의 NFC 기능을 이용한 여러 서비스들 중 모바일 쿠폰 서비스인 mCoupon 서비스의 시장 활성화를 위해 다양한 인프라가 구축되고 있다. 하지만 mCoupon 서비스는 아직까지 관련 보안 연구가 미흡한 상태이며 보안 기술 개발 속도 또한 현재 구축되고 있는 다양한 인프라에 따라가지 못하고 있다. 따라서 본 논문에서는 NFC 환경에서의 mCoupon 서비스를 위한 안전하고 효율적인 쿠폰 시스템을 설계하고 구현한다.

최근 스마트폰에 탑재된 NFC를 통한 결제 서비스의 시장이 각광을 받고 있다. 사용자는 자신의 신용카드 정보와 같은 지불 수단을 스마트폰에 탑재된 NFC 장치에 기록하여 리더기에 그 정보를 보냄으로써 간편하게 결제를 할 수 있게 되었다. 하지만 무선 신호의 특성상 사용자의 정보가 외부로 노출될 가능성도 배제할 수 없으며, NFC 데이터를 읽는 리더기가 신뢰 가능한 리더기인지 알 수 없는 보안 취약성이 존재한다. 본 논문에서는 NFC를 통해 안전하게 데이터 통신을 할 수 있도록 정의된 NFC-SEC 표준에 대해서 살펴보고, NFC-SEC 프로토콜에서 피어 간의 상호 인증의 필요성에 대해서 말한다.
