The percentage share of mobile gift card certificate in the gift card market has increased significantly each year. But from a consumer perspective mobile gift card certificate has several problems. Specifying unfair terms in Fair Trade Commission has improved slightly, but the problem is not replaced with the equivalent authority that issued the vouchers can not be solved. The exchange between users the most realistic way to solve this problem is to create an environment as possible. In conclusion, The deal will be possible to build a mobile gift card certificate brokerage trading in a convenient and reliable P2P-based. If the System for mediating transactions of a mobile gift certificate has created a healthy retail environment, such as the expansion of the voucher market, reduce social costs may be creating.

This research aimed to design and develop a mobile-website mixed business model and smartphone based mobile application for the purpose of mobile fashion content distribution. We have implemented a mobile interface and trading system supporting self production of content, use, share, and user's self-up. And we proposed its market access strategy for the expansion of fashion contents transactions. To do this, the existing status of research and benchmarking for mobile app of fashion contents related were studied. As a result of the study, Android, iOS-based mobile applications were developed, but there are some business problems such as low awareness, low entry barriers, and the poor fashion content compared to the size of industry. Because this system provide the fashion contents of affiliated companies to users, it needs to expand cooperation and to promote the partnership with fashion blog, cafes, and fashion magazines.

Financial transactions using a mobile terminal and the Internet is activated, it is a stock exchange enabled using mobile devices and the Internet. Koscom in charge of IT operations of securities transaction-related in (securities ISAC), to analyze the vulnerability of information security related to securities transactions, which corresponds to running the integrated security control system. Online stock trading is a subject to the Personal Information Protection Act, electronic systems of related, has been designated as the main information and communication infrastructure to, damage financial carelessness of the user, such as by hacking is expected to are. As a result, research on the key vulnerabilities of information security fields related to securities business cancer decoding of the Securities and Exchange packet, through the analysis of security events and integrated security control is needed.

This paper proposes an E-Commerce service that supports large quantities of food waste sales generated by collective residences, including apartments, to consumers in urban areas, such as livestock farmers, through online transactions. Unlike general E-Commerce, the proposed service uses a smart food waste bin equipped with an IoT-based sensor and communication module to automatically collect the location information of each apartment and the amount of food waste to be displayed in a specialized E-Commerce platform. The key of this system is to provide information and sell it to consumers. The smart food waste bin periodically delivers its current capacity and location using a weight sensor, GPS sensor and LoRa communication module to a cloud-based database to be used in web or mobile applications. The proposed E-Commerce service is expected to help resolve the food waste disposal problem and revitalize the local economy by linking with a service that delivers food waste from each apartment to a nearby location where the buyer is located.

In the resent years, the term mobile agent is probably one of the most overused words in many appliable areas of distributed open systems as electronic commerce and electronic data interchange, and it has very different meanings in the area of artificial intelligence, network management, or distributed systems. However, the use of mobile agent adds significant problems, primarily in the area of EC/EDI. Therefore it is very important to control the roaming agents to keep one's privacy or property in distributed open networks. The surge in secure intranets for commercial applications provides a robust, secure environment to which trading partners can increasingly entrust their interactions to some mobile agents. In this paper, we introduce a mechanism to protect mobile agent itself from the malicious server he is visiting and also we introduce a mechanism to protect vital resources of the open systems as internet.

An efficient hybrid ARQ scheme based on the rate compatible block turbo codes has been proposed, and its performance has been analyzed. System efficiency is improved by means of adaptive rate code transmission using channel information, trading off bit rate for channel codes, with resulting energy saving. The rate adaptation scheme improves power efficiency while keeping packet delay minimized. On the other hand, power dependant strategies reduce power consumption. Simulation results show that the benefits obtained are very encouraging. The modified hybrid ARQ schemes with the channel information and efficient retransmission structures highly improve the throughput performance in the satellite communication system. Therefore, proposed schemes could be used in future communication systems.

An electronic commerce model is proposed which distributes digital content in mobile environment. This model resolves the problems caused by various digital content and complex distribution structure. The online distribution systems under the wireless environment include many different factors from the conventional offline and wired networks. Furthermore, the multimedia content may be propagated more easily and illegally. The scheme to protect the rights and profits of people related to the copyrights of digital content is needed. In this paper a framework for electronic commerce of content distribution under the wireless environment based on MPEG-21 is proposed. This model can be applied to the digital rights management system and utilized to protect the rights of trading entities in online distribution of electronic commerce.

As a result of New media that affects the marketing system, it is appeared a new marketing system called Market Platform in terms of market governance of trading. Market Platform is a new marketing system for ideal market system through the community structure from a hierarchy structure. It is determined that Market Platform as the role of adjustment of each side of market, buyer and seller, developed an existing marketing system. In this study, to target the Market Platform has recently emerged as the center of the market management in the new media environment. This study investigates what characteristics and impact of infrastructure of Market Platform will affect the cognitive impact on both buyers and sellers to clarify the impact on the self efficacy of the shopping process. Through this investigation, modeling for the impact that new media environment will attract Market Platform will be developed from the investigation of attractiveness of mobile market platform environment. Changes in the technical media environment gave the characteristics of the customer in the market platform, so consumers could involve not only consumed, but also manufactured. Thus, it is possible to increase the attractiveness if market must be able to not only for the convenience of shopping, but also make people to enjoy the experience of value co-creation. In other words, the new media, as a result of affecting the marketing system, mobile market platform is organized around the market of communication base. Network centrality, visible openness, ubiquitous multiplexity, 3 properties of new media increase the market self-efficacy of their customers. Therefore, the structure of market platform that enhance self-efficacy has higher attractiveness.

In this paper, we suggest a soft keyboard, called easy keypad, that we use only for login information input in smart devices. Especially, as easy keypad is applied to MTS(Mobile Trading System) we suggest easy keypad in MTS. Easy keypad UI in MTS represents 20 letters and users input login information by using 20 letters. We suggest protocol which decides letters represented in easy keypad UI, which is code for users to input login information by using 20 letters. We analyze easy keypad's safe degree for soft keyboard security threat, especially when it comes to point hacking, we suggest comparison among original soft keyboard's safe degree. Also we suggest mathematical fomula for measuring soft keyboard's convenience and then we analyze the result of soft keyboard's convenience by the presented mathematical formula.
