In this paper, we propose about NFC-based mobile Easy Payment System. Already announced about kind of similar payment system by use smart phone NFC function. However this proposition system will uses an encrypted token and user indirect authentication. This feature makes through to simplify payment without other input necessary information. Also my proposition system has easy security certification process. This mean my system does not adequately to use payment of a large amount. But in retail payment will be very useful payment system.

인터넷은 21세기 산업발전의 원동력이며, 인류 역사상 가장 빠른 속도로 확산된 미디어로서 현재 인터넷 비즈니스는 유통은 물론 금융, 주식거래, 경매, 오락, 택배 서비스 등 산업 전반으로 빠르게 확산되고 있다. 빠른 환경변화와 더불어 다양한 인터넷 사업 모델이 계속 새로 등장하고 있으며, 그 중 전자상거래는 더 이상 새로운 기술이 아닌 우리 환경의 필수적인 요소로 자리잡고 있다. 현재 모바일 전자상거래는 시장 형성의 초기 단계로 무선 인터넷 시장의 상황과 수익 창출의 관점에서 볼 때는 무선 인터넷 포탈 서비스의 핵심이 될 것이다. 이러한 요구에 부응하기 위하여 본 논문에서는 전자상거래를 위한 시스템을 UML (Unified Modeling Language)로 설계하여 시스템의 특성에 맞게 사용자가 시스템을 사용할 수 있도록 한다.

BYOD(Bring your own device) 환경에서는 개인의 스마트 기기를 이용하여 회사 시스템을 이용하는 것으로, 개인의 단말을 업무에 이용하는 만큼 사원의 개인정보, 고객의 개인정보, 신규 사업 아이템, 상품의 거래내역, 계좌번호 등 유출시 막대한 손해를 발생시키는 사내 정보 유출에 대한 문제가 발생 가능하다. 회사 시스템을 관리하기 위해 개개인이 사용하는 다양한 종류의 단말에 맞는 설정이 필요함으로 즉각적인 대응이 어렵다. 때문에 위 같은 문제를 해결하고자 삼성이 개발한 듀얼 OS 구조의 KNOX가 제안되었으나, 특정 단말과 OS에 의존적이어서 다양한 종류의 단말에 적용하기 위해서는 지속적 개발이 필요한 단점이 있다. 다른 방법으로 MDM(Mobile Device Management) 시스템을 제안하였지만 새로운 모바일 단말에 대한 즉각적인 대응이 힘들며, 유지보수에 많은 시간과 투자가 필요한 단점이 있다. 따라서 본 논문에서는 단말에 의존적이지 않으면서, 기업의 정보를 보호하기 위하여 클라우드 기반 정보 유출 방지 플랫폼을 설계하고 제안한다.

Recently, various payment services using mobile terminals are emerging and many users are using this service. This study is an empirical study on the effect of system factors(convenience, reachability, compatibility) of mobile simple payment service on trust, positive affect, mediated by customer perceived risk. A survey was conducted for this study, and a structural equation model was analyzed with PLS. Results showed that convenience, accessibility, and compatibility affect risk, and risk affects trust and positive affect.

The main purpose of this paper is to propose a sophistication framework for a global manufacturing network (GMN) driven by a mother company to autonomously propagate and coordinate transaction data that are exchanged among manufacturing partners. The framework is based on conceptual fundamentals of previous research that provide a step toward ultimate successful collaboration in the supply chain and employs mobile agents for the coordination and propagation of transaction data. Maintaining the integrity of transaction data linked to a huge information web is difficult. With the sophistication functionalities of this framework, it becomes easy to effectively control the overall GMN operations and to accomplish the intended goals. The current level of sophistication focuses on the transaction data propagation. The sophistication level may be expanded up to business intelligence in the future.

인앱결제 시스템이란 애플리케이션(앱) 내 결제 시스템을 통한 결제행위를 말하며, 다운받은 앱은 무료일 수 있지만 앱 내에서 별도의 유료아이템 등을 구매 할 경우 유료결제가 일어날 수 있다는 것을 뜻한다. 인앱결제는 한번의 등록을 거친 후 단 한번의 비밀번호 입력을 통하여 결제가 된다. 스마트폰 보급 확대에 따라 오픈마켓의 게임 등 모바일콘텐츠 거래 증가로 유료 콘텐츠 결제와 관련한 이용자 피해가 급증하며 이용자 불편, 불만(인앱결제 피해)으로 인한 피해가 다수 발생하고 있다. 본 논문은 이러한 휴대폰 인앱결제 시스템의 문제점을 파악하고 인앱결제로 인한 피해 예방을 하기 위한 보안서비스를 제시한다.

The new environment of music service has brought changes in digital music industry. Today, various forms of music contents are presented in ubiquitous environments. Thus, securing various contents becomes very important in monopolistic competition of music market. Under the circumstance, web 2.0 provides a networking environment to form diverse relations. Social Network Service (SNS) is a service to emphasize people relation and is different from information-centered Internet service. And mobile SNS becomes popular as Smartphone rapidly increases. NeowizBugs merged with NeowizInternet managing Sayclub of a music-specified SNS site. And the firm confirms comprehensive contents by making ties with SM entertainment. Thus, the integration corporation secures and manages a new business model by linking digital contents with SNS. Generally, music-specified SNS has advertisement business model and uses a recommend system utilizing the database of users. By introducing the case of NeowizBugs, this study tries to identify the success strategy of music distributors fitting ubiquitous environment including web 2.0, mobile SNS, Smartphone, etc.

As mobile device is becoming more popular, E-Commerce changes into M-Commerce. Especially, IMT-2000 (International Mobile Telecommunication 2000) service is prepared for M-Commerce and this has USIM (Universal Subscriber Identity Module) as a core of certification of individuality and transactions. As a result, the area of mobile service going to expand by USIM. But, mobile services using USIM leave much to be desired, and developed application don't variety. In this paper, for the efficient design of USIM, the structure of USIM and protocol is analyzed, and secure payment solution in USIM is proposed. Specially, offline payment system is proposed for the verification of proposed protocols including security, saving, and calculation of balance. finally, the simulation of proposed payment system on USIM is performed using Java Card.

Instead of existing cell phones, PDAs are observed as leading wireless Internet devices recently Numerous applications are developed by extended usage of PDAs and it should be installed appropriately according to devices. Furthermore, when battery is discharged, all data stored in RAM(Random Access Memory) becomes obsolete. So it should be recovered or reinstalled from flash memory, backup media or something. In this paper, we present an automatic application installation system(PAIS : PDA Automatic Installation System) to solve problems that users have to install applications by themselves whenever it is necessary. With this system, users feel comfortable by saving time and effort to install each applications and application development companies save cost needed to make materials illustrating installation process. Consequently PAIS may flourish wireless Internet business.

Due to a rapid advancement in the electronic commerce technology, the payment method varies from cash to electronic settlement such as credit card, mobile payment and mobile application card. Therefore, financial fraud is increasing notably for a purpose of personal gain. In response, financial companies are building the FDS (Fraud Detection System) to protect consumers from fraudulent transactions. The one of the goals of FDS is identifying the fraudulent transaction with high accuracy by analyzing transaction data and personal information in real-time. Data mining techniques are providing great aid in financial accounting fraud detection, so it have been applied most extensively to provide primary solutions to the problems. In this paper, we try to provide an overview of the research on data mining based fraud detection. Also, we classify researches under few criteria such as data set, data mining algorithm and viewpoint of research.
