According as information society has been raised, many countries of the world have taken a lot of interests in e-government implementation. The several guidance countries already have offered people various administrative service and popular enmity service in the Internet conveniently, People can use e-government service more conveniently by the Internet, but important personal information or state secret can be leaked in the Internet. Because of these security vulnerabilities, a lot of countries are constructing security infrastructure that can protect personal information. In this paper, we examine e-government construction trends of the several guidance countries, and propose security considerations to provide safe and reliable e-government service.

This study is intended to examine how strategic nature of the alliaTnce, characteristics of input resource, communication activities will affect the strategic partnership(trust/commitment) and performance in the strategic alliance between internet shopping mall and the third party logistics. The variables affecting the partnership(trust/commitment) between internet shopping mall and the third party logistics produced the result to prove what I intend to suggest in this study, in verifying four hypotheses such as strategic importance, complementation of resource, quality of communication, share of information. It was found that the partnership have a significant positive influences on the performance of strategic alliance. As most of the domestic Internet shopping malls employ the third party logistics strategically, the implications from this study are as following: First, this study attempts to find out factors influencing partnership(trust/commitment) and the performance of strategic alliances. Second, the results that strategic partnership can build up based on the long term thrust and commitment implies operation and management are important during operation of strategic alliance. Third, this study provides the model of determinants of partnership and performance in the strategic alliance for logistics services which is one of the factors consumers in the Internet shopping mall are most sensitively response to, and quantifies the model through the empirical analysis.

Currently, almost of all the Internet users have as many IDs as the number of sites they have subscribed for, The users should memorize and input every independent ID and password whenever they want to login to the system. Although ID management system is used to solve this problem, 10 and password management will become more complicated in the forthcoming ubiquitous computing environments because so many computers will be interconnected on various kinds of wired and wireless networks, Furthermore, it is not enough to use the existing single Circle of Trust (COT) ID management system for the forthcoming computing environments. To solve this problem, the paper proposes ID federation models in multiple COT domain and implements an ID federation system that can be scaled to mobile computing environment as well as wired computing environment. The proposed ID federation models has been verified to operate with no problem between the systems in different trust domains by doing the ID scaability test.

Fingerprint has the characteristics that do not change with time and is unique to an individual. And fingerprint identification is considered the best choice for most biometric applications because of its accuracy, speed, reliability, non-intrusive interfaces and cost-effectiveness. In this paper, we applies fingerprint Identification to web site login to raise the quality of personal identification when we use e-commerce, internet banking, stock dealings, shopping mali, etc. The system implemented in this paper consists of embedded module to carry out fingerprint identification, web server and web site. Existing system carries out fingerprint identification in the web server, but the system Implemented in this paper carries out it in client. Therefore the loads of server are reduced and the confidence of internet service is improved because login is forbidden without fingerprint identification success.

There are many studies about the relationship between customer satisfaction and SCM, web site quality or online Word of Mouth (WOM). When a customer wants to purchase any product online, he has to watch the detail of a online shopping web by computer. So the web sits' quality can be very important for the customer to get enough information. Recently, internet shopping malls are very much prospered. To understand why these kinds of internet transactions become very popular, this study investigates a possible effect of such crucial factors as web site quality, supply chain management(or deliver service), and online Word of Mouth(WOM) of an internet shopping mall to its customer satisfaction and trust, eventually leading to purchasing product and services. This study develops a experimental research model and tests it based on 170 survey response using regression analysis.. The finding of this research implies that system quality, information quality, quick and correct, accurate delivery service, and online WOM are influential factors to the performance of online shopping mall, while design quality, cost of delivery do not affect relationship significantly.

The development of the Internet of Things(IoT) requires large computational resources for tasks from numerous devices. Mobile Edge Computing(MEC) has attracted a lot of attention in the IoT environment because it provides computational resources geographically close to the devices. Task offloading to MEC servers is efficient for devices with limited battery life and computational capability. In this paper, we assumed an industrial IoT environment requiring high reliability. The complexity of optimization problem in industrial IoT environment with many devices and multiple MEC servers is very high. To solve this problem, the problem is divided into two. After selecting the MEC server considering the queue status of the MEC server, we propose an offloading decision algorithm that optimizes reliability and energy consumption using genetic algorithm. Through experiments, we analyze the performance of the proposed algorithm in terms of energy consumption and reliability.

In Korea, The Consumer Protection Law in Electronic Commerce, which came into effect in July 2002, forced internet shopping malls to provide a minimum of 7 forms of business information, including the name of the business, the name of the representative, geographical address, telephone number, fax number, e-mail address, and business license number, so that consumers could easily identify them. To investigate the shopping malls which do not provide their business information, can lead to confidence in the electronic commerce environment. To investigate the completeness of the business information with the internet shopping malls, this paper proposes the methods of gathering URLs of internet shopping malls, of extracting business information attributes, and an architecture of the agent system. Information extraction in our research is based on synonyms and indicator words of the attributes. With the experiment we showed that the accuracy of our agent system to find out the right business information is 89.3%.

VoIP(Voice over IP)는 차세대 인터넷 서비스에서 두각을 나타내고 있는 기술이다. 특히 SIP는 텍스트 기반의 프로토콜로써 구현이 쉽고 다른 서비스와의 호환이 쉬러 기존의 H.323을 대체할 기술로써 더욱 주목을 받고 있다. 하지만 SIP에서도 아직 논의되어야 할 부분이 많이 있다. SIP는 전송 프로토콜에 독립적인 응용계층 프로토콜이다. 따라서 종단대 종단 신뢰성 메카니즘이 필요하다. 본 논문에서는 SIP의 응답 메시지의 신뢰성을 위한 메카니즘을 소개하고 시뮬레이션을 통해서 그 성능을 분석한다.

인터넷의 보급 확산이 증가됨에 따라 컴퓨터 시스템은 점차 복잡하고 규모가 커지기 때문에 시스템 장애로 인한 피해도 증가하고 있다. 컴퓨터 시스템의 신뢰도가 중요시되는 가운데 오늘날은 하드웨어 보다 소프트웨어의 신뢰도가 더욱 중요시되고 있으며, 소프트웨어의 신뢰도를 향상시키기 위해서는 소프트웨어로 인한 결함 발생을 줄여주는 것이 중요하다. 본 연구에서는 작업전이 시간을 고려한 주-백업 시스템에서의 모델링을 제안하였으며 가용도와 손실비용에 대한 분석을 하였다. 분석을 통해서 작업전이 시간이 주-백업 서버 시스템에서의 재활정책에 가장 중요한 요소임을 발견하였다.
