The use of smart phones has had a great impact on the mobile internet business. It shows a lot of growth in the healthcare sector not only commerce, advertising, billing, games, video content, media, amd O2O business. The United States has eased the regulations for healthcare apps smart phone devices in 2015, and China has established a five-year road map to solve shortage of doctors and hospital beds by utilizing mobile devices such as wearable in the same year. The application of wearable devices in the medical field is gradually increasing in Korea too, but there is a security problem as leading challenge. Security incidents in non-ICT sectors such as financial, medical, etc. have increased by using ICT each year. Personal information leakage is also increasing in field likely occurring the potential secondary damages such as financial fraud, illegal promotions, insurance and pharmaceutical companies abuse. In this study, we analyze malwares as the mobile threats, the five risks of mobile smart phone, mobile use cases and the mobile threat countermeasures for healthcare.

E-Commerce is suddenly spreading in a daily life. A rights trading system is a system that circulates digital-tickets such as plane tickets, software license, coupon. There are two main approaches so far account-based and smart-card based systems. The NTT Proposed FlexToken, a new smart card based copy prevention scheme for digital rights. They Proposed using pseudonymous self certified keys of Petersen and Horster in order to ensure anonymity of users. However. Petersen and Holster's scheme should register a pseudonymous key pair at TTP (One-time) every time so that users create the signature which is satisfied with unlinkability property In this paper, we propose a new anonymous rights trading system using group signature. This paper has a meaning having applied to digital rights trading system an efficient smart card based group signature.

The bill of lading serves to link imports and exports. It is the last document issued in the export process and is the most important document before import and export as it is the first document required for importers to take over goods. Transfer the right to the goods to be transported to another person through endorsement. The role and importance of the bill of lading has already been suggested in many previous studies and the trading partners are fully aware of it. In addition, all countries and international organizations recognized the importance and enacted various laws and systems in relation to possible legal problems and they have become customary in practice. However, trade fraud that exploits the characteristics of the bill of lading may occur. In order to solve this problem, various attempts related to the electronic rights transfer of the bill of lading began to be carried out, and many institutions and companies are still trying to develop a new system. As a result of these efforts, electronic bills of lading, such as bolero, appeared, and electronic bills of lading, which can transfer rights in an electronic way, appeared. Therefore, this study intends to present the feasibility of the introduction of smart bills of lading after examining the current status of electronic bills of lading and the introduction of block chain technology-based bills of lading.

Smart Factory refers to a factory that can be controlled by itself with an intelligent factory that improves productivity, quality and customer satisfaction by combining the entire process of manufacturing and production with digital automation solutions. The manufacturing industry around the world is rapidly changing, with Germany, Europe, and the United States at the center. In order to cope with such changes, the Korean government is also implementing a policy to spread the supply of smart factories for small and medium-sized companies, and related ministries and agencies such as the Ministry of Commerce, Industry and Energy, the Ministry of SMEs and Venture Business, the Korea Institute of Technology and Information Promotion, and local technoparks, as well as large companies such as Samsung, SK and LG are actively investing in smart manufacturing projects to support smart factories[1]. Factory Automation (FA) construction has many issues regarding the connection of heterogeneous equipment. The most difficult aspect of configuring various communications from various equipment is the reason. Although it may not be known if there are standards or products made up of the same company, it is not easy to build equipment that is old, up-to-date, and different use environments through a series of communications. To solve this problem, we would like to propose a method of communication using Modbus, one of FieldBus, which is one of the many industrial devices of PLC, a representative facility control system, and is used as a communication standard.

Currently, the domestic traditional market has not escaped the swamp of stagnation that began in the early 2000s despite various projects promoted by many related players such as the central government and local governments. In order to overcome the crisis faced by the traditional market, various R&Ds have recently been conducted on how to build a smart traditional market that combines information and communication technologies such as big data analysis, artificial intelligence, and the Internet of Things. This study analyzes various previous studies, users of traditional markets, and application cases of ICT technology in foreign traditional markets since 2012 and proposes a model to build a smart traditional market using ICT technology based on the analysis. The model proposed in this study includes building a traditional market metaverse that can interact with visitors, certifying visits to traditional markets through digital signage with NFC technology, improving accuracy of fire detection functions using IoT and AI technology, developing smartphone apps for market launch information and event notification, and an e-commerce system. If a smart traditional market platform is implemented and operated based on the smart traditional market platform model presented in this study, it will not only draw interest in the traditional market to MZ generation and foreigners, but also contribute to revitalizing the traditional market in the future.

With the active Internet e-commerce and the financial sector, mutual authentication between users and service providers has become very important. Because ID- and password-based authentication is of low security, one-time password authentication methods are widely used. The existing one-time password authentication scheme of S/Key authentication method is fraught with a number of issues in addition to plain text transmission, and the method of Kim Gong-ki et al. does not offer suggestions for session key generation and distribution method. Proposed in this paper is a protocol that solves these problems.

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.

This paper clarifies the change in international technology standardization as a change in innovation. The change comes to be shown in how to take the consensus standard. The tendency to standardize the systematized concept is a rather arduous and complex endeavor. This paper focuses on Mitsubishi Electric Corporation as such a case. The results interpreted from the approach of closed innovation, open innovation, and social innovation. The following findings are clarified by. 1) The consensus standardization is open innovation in which the enterprise creates value. 2) When the value creation is large, the possibility of the maximization of such value capture that achieves the earnings acquisition can be improved. 3. The innovation of the consensus standardization is reciprocal for the stakeholder. The possibility for open and social innovation to supplement the success in innovation mutual and to achieve an effect is suggested.

네트워크가 발전하면서 사용자들은 쉽게 접근할 수 있는 인터넷을 선호하게 되었다. 또한 많은 개발자들은 손쉽게 배포할 수 있는 인터넷 기반의 시스템을 개발하였다. 그러나 인터넷은 많은 양의 서버 리소스와 대역폭이 필요할 뿐만 아니라 응답 속도가 느리다. 따라서, 인터넷을 통한 통합적인 시스템은 더욱 강력한 기능을 필요로 한다. 그러한 기능을 스마트 클라이언트가 제공한다. 대표적으로 빠른 응답 능력, 손쉬운 배포와 관리된 업데이트, 오프라인으로의 사용 등이 있다. 이러한 풍부한 기능을 가진 스마트 클라이언트를 적용하여 인터넷의 장점은 사용하고 단점은 보완할 수 있다. 본 논문에서는 이러한 스마트 클라이언트를 적용한 전자상거래 시스템을 설계 및 구현하였다. 이러한 결과 전자상거래 관리자는 판매자에게 관리시스템의 배포가 쉽게 이루어지며 판매자는 관리시스템을 통해 손쉽게 상품을 등록하고 고객의 주문을 관리할 수 있었다. 또한, 고객은 요청한 기능에 대한 빠른 응답으로 구매시간을 절약할 수 있었다.
