기존의 모바일 대면거래 시스템은 결제자가 결제를 하기 위해 결제정보를 상점에 제공하게 된다. 결제정보는 거래정보와 함께 중간 통신단계를 거치면서 각 단계에 수집 보관된다. 이 정보는 거래정보와 결제정보가 함께 전달되기 때문에 정보가 노출되면 조합을 통해 대상을 특정할 수 있으며 생활패턴 등 개인의 사생활까지 노출된다. 하지만 수집 보관된 정보에 대한 법적인 관리 지침이 미흡하기 때문에 개인정보를 수집 보관하는 업체가 많아질수록 개인정보의 유출 가능성은 더욱 커지게 된다. 따라서 본 논문에서는 개인정보의 수집을 최소화하고 결제정보와 거래정보를 나누어 보냄으로써 정보에 해당하는 대상을 특정할 수 없게 하는 방법을 새롭게 제안한다.

In this paper, we propose the CRM service model for analyzing and managing location based data collected by Wi-Fi and BLE. As mobile devices became personalized, enterprises became interested in individual location, and location based mobile marketing started to stand on spotlight. Location based proximity marketing is developing along with contactless data transmission technology, and payment system that uses NFC, Beacon that utilizes BLE, as well as advertisement via Wi-Fi are being serviced. We suggest the model that mobile devices can be detected and identified by MAC address with the need of being connected to Wi-FI or Bluetooth interface. MAC addresses are not associated with any specific user account or mobile phone number. The idea is to be able to measure the amount of people which are present in a certain point at a specific time, allowing the study of the evolution of data analysis and offers effective information for decision-makings.

Mobile RFID technology as a typical Convergence technology combines RFID communication, mobile communication and network infrastructure, and information processing technology. As it enables users to communicate with the surroundings, Mobile RFID technology is now recognized to serve as the basis technology for the Ubiquitous Information Society where users can get the needed information anytime and anywhere. Through lots of efforts for the early technology development and standardization activities on Mobile RFID technology, Korea has been leading technology standardization as well as technology initiatives. Thus, this research paper describes the domestic and the international standardization activities on Mobile RFID technology as well as the latest standardization status. Further this paper summarizes the major standardization issues, and then proposes the standardization strategy of Mobile RFID technology by analyzing the relevant and influential factors.

The volume of electronic banking service via smart phone is expected to increase dramatically under smart convergence environment. Under such circumstances, the effort to establish the mobile electronic banking culture which took a major step forward from the conventional electronic commerce method is essential. It is necessary to standardize the mobile payment infrastructure in order to resolve the initiative conflicts between financial institutions and newly launched non-financial institutions. Furthermore, a domestic and international strategy is required as the number of NFC technology based smart phone transaction business is increased. As various types of business enter the electronic commerce field, efforts to resolve the dissatisfaction of the customers are critical. Additionally, security is one of the significant issue due to the conversation process to open-type operating system. This study surveyed and analyzed the current domestic and foreign status, the problems in Korea, and suggested an effective counterplan and policy, which could be helpful in governments' preparation for electronic commerce policy.

There have been consumer needs for mobile payment system due to the rapid increase in the number of smartphones and the use of them. In tum, the market has been expanding as IT companies begin to participate in the mobile payment system business. Moreover, since the system supports better services not only covering payment service but also interworking with various apps in devices, it has been maximizing the consumer convenience. Although the convenience increased due to the mobile payment system, the vulnerability in security also increased; and smartphone users have been afraid of using the mobile payment system. This study is to examine Samsung Pay and Apple Pay, to present the vulnerability, and to suggest a countermeasure.

Smart building gate security control system using smartphone integrated with near field communication (NFC) has become part of daily life usage these days. The technology change in replacing RF NFC device using visible light communication technology based approach growing faster in recent days. This paper propose a design and development of gate security control system using color code based user authentication ID generation as part of an intelligent access control system to control automatic door open and close. In this approach gate security access control use the recent visible light communication technology trends to transfer the user specific authentication code to door access control system using color code on smartphone screen. Using a camera in the door access control system (ACS), color codes on smartphone screens are detected and matched to the database of authenticated user to open the door automatically in gate security system. We measure the visual light communication technology efficiency as a part of the research and the experiments have revealed that more than 95% users authenticated correctly at the suggested experiment environment on gate security control system.

As mobile equipments have been developed while we use public transport, several applications for knowing arrival informations of public transport have happened. But these only provide public traffic informations simply, these solving applications for problems and inconvenience that we ride/get off public transport do not exist. These inconveniences are occurred mainly on tagging card, when tag error or without advanced preparation are happened, these caused for delay while we use ride/get off. Also, these caused for traffic congestion. In this paper, in order to solve these problems, we use Beacon and we overcome narrow range of NFC and we implemented for Android application for decreasing delay while several people could ride/get off simultaneously.

Recent developments in internet technologies has enabled widespread growth of embedded systems like Arduino, Raspberry Pi and other smart home systems. A research in the industrial sector on the utilization of the board has been made. The development needs of the embedded board in a reagent bottle case system has been highlighted. Current reagent Management System has to hold and manage the reagent itself is mostly to save the program using handwritten or machine. In addition, there is a risk to the system during the vulnerable zone administrator to manage the situation of the reagent bottle case can lead to a massive fire. In this paper, reagent bottle case RFID readers and data in real-time is monitored by attaching a sensor management through the database and sends a warning message to the mobile device of the administrator in real time during hazardous situations in the reagent bottle case. This is improve the reliability and efficiency of reagent bottle case.

This study is to analyze the applicability of new technologies to be applied to the foreseeable future's library. For this purpose, we measured the users' intention to accept the service by using the NFC based self-check out service as a new technology applicable to the library. Based on the Unified Theory of Acceptance Use of Technology (UTAUT), research models were derived, and the structural relationships between performance expectations, effort expectations, facilitation conditions, and perceived risks were analyzed. As a result of the analysis, perceived threats in the library did not affect the intention to use, and the performance expectation, effort expectation, and facilitation condition partially affected the intention to use. The gender of the moderator variable, there were some significant difference in promoting conditions.
