최근 스마트폰을 이용한 모바일 금융 서비스 시장이 증대되고 있으나 개방된 무선인터넷을 사용하며 도난 및 분실의 위험이 큰 모바일 환경의 특성으로 인하여 안전한 인증 기술의 필요성이 대두되고 있다. 최근 모든 플랫폼에서 사용할 수 있는 오픈 뱅킹에 대한 수요와 편의성에 대한 요구로 기존의 공개키 기반의 인증 방식인 공인인증서를 대체할 수 있는 새로운 인식 기술이 요구되고 있다. 사용자의 생체 특성을 이용하는 바이오 인식 기술은 모바일에 탑재되어 있는 기본입력 장치를 이용하여 바이오 정보를 인식하는 것이 가능하며 별도의 소지 없이 간단히 인식이 가능하기 때문에 모바일 지급 결제에 공인인증서를 대체할 수단으호 사용될 수 있다. 아직 모바일 지급결재에 바이오인식 기술을 적용하기에는 인식률의 정확도 향상이 필요한 상태이나 이를 위한 소프트웨어 및 하드웨어적인 개선이 이루어진다면 안전한 모바일 지급결제 환경을 구축할 수 있을 것으로 기대된다.

본 논문에서는 자바 모바일 플랫폼을 기반으로 하는 M-Commerce 보안 플랫폼을 검토하고, J2ME 기반 CLDC와 MIDP를 이용해서 M-Commerce 전자지불을 위한 휴대용 전자지갑 구현방안을 제시한다. 본 논문에서 제안한 방안은 무선 인터넷 환경에서 신용카드 결제 방식으로 지불할 경우 관련 중요 정보를 안전하게 전송하고, 대금 결제를 할 수 있도록 한다. 그리고, 무선인터넷 응용프로토콜 WAP 방식의 보안을 고려한 WTLS 보안 메커니즘을 이용하고, J2ME 기술을 기반으로 하기 때문에 향후 IMT2000에서도 사용 가능하다.

The purpose of this research is to verify the sellers' preference of online shopping platform and simple payment service among the Korean domestic online shopping platforms and analyze which factors they consider depending upon their preferred platform and service. The result of this study shows that the reputation, ease of payment, and ease to navigate of online shopping platform should be considered seriously in choosing the online shopping platform. Also, the usability, ease of payment and service fee of simple payment service are influencing factors to select simple payment service for sellers. Meanwhile, the result confirms that the degree of reputation, ease to navigate, service fee, and ease of payment differs on each selected online shopping platform. Also, the degree of usability and security in simple payment service is different between each chosen simple payment services.

Currently, most of the mobile game market releases games through Google play and App Store, which have a high share. Because it uses a third-party platform, only the payment API system provided must be used, and third-party platform pays the game company after excluding certain fees. Because game companies do not know whether or not to refund items and cannot get back items through third party transactions, users and professional websites are continuously appearing that exploit refunds. In this thesis, after analyzing problems of existing payment method and presenting a payment model using blockchain smart contract, we analyzed differences from existing model in terms of transparency, decentralization(fee), efficiency, and as a result, payment model using smart contract has low commission through P2P transaction without third parties and transparent transaction record, preventing item forgery and refund. Later, the proposed payment model would lead to the culling of companies acting on behalf of refunds for words that deviate from moral ethics such as "Refund OK even with items" and resolve the problem of unreasonable fees that arise through third-party platforms.

Local area festivals have grown on a scale for the past 20 years, but have suffered ups and downs. Through the trial and error of the festival operation, problems such as prediction of the number of visitors, planning of event scale, calculation and expansion of sales volume, and management of various participants in the duration were highlighted. To solve, this study designed and developed a mobile payment system and festival operation management system for local scale festivals as a platform operating system of web and app combined. The results of this study presents four basic functions. It includes ticketing management, attendance identification and entrance control, charge of festival currency and use of payments, real-time provision and management of related information, and performance reporting for each role. It was applied to local festivals in practice as to enable local shop owners to participate in advertisements or sponsorships and confirmed their contribution to local commercial market and the revitalization of festivals through this system.

Recently, most of the modern people used a second mobile device(two degree mobile device). Mobile devices are affecting all areas of human life, consumer electronics, transportation, manufacturing, and finance. On this paper, we propose a model-driven development based interaction model that can be used in the development of mobile payment system, which is the latest buzzword pins of the various application fields of mobile devices Tech (Fin-Tech) sector. Using a model-driven development based models do not depend on the Platforms (PIM), we propose a model for interaction between devices which can be reused when developing mobile billing app. A model-driven development based mobile applications use the reusable of interaction models development program analyzed the bus fees automatic payment application by a beacon.

In mobile market which has been developed drastically, short distance mobile Near Field Communication is becoming the conversation topic. Google adopted this NFC technology to Android 플랫폼 for securing the leadership and many another countries including domestic companies are putting spurs to develop service and technology by connecting mobile carrier and the financial. Within this circumstance, most noticeable issue is securing stability of nfc application service. Android 플랫폼 is operating system of mobile device and also a software stack which is required limited hardware and immediate response. However, since its structural characteristic which is suitable for limited hardware, the response is not quite stable for real time process. That is, this paper researches by analyzing real time response of NFC related library provided from Android 플랫폼 and applying the result to NFC application for securing stable data process and response.
