Recently, payment method is one of the most hot issues for transaction of contents in mobile and internet markets. Many kinds of mobile contents services are rapidly growing with the combination of internet application services. Payment method algorithms are demanded for the stable transaction between producer and consumer. Security protocol algorithms are widely adapted for mobile Platform terminals. In this Paper, we described security mechanism for the current wireless internet services and compared with the performance result. There are security protocols that based on java machine platform or WAP protocols. The system is based on J2ME technology for the java mobile platform. Based on this technology, a security system is proposed for the service of mobile commerce electronic payment. The system is designed for the stability of transaction so that it enables to apply into many kinds of internet payment system.

The environment of If is, currently, on its developing process to the period of Web Service, Ubiquitous, and Telemetics which not only enable computer and internet to be utilized like the water or the air, but also be a new motivating force for its advance. In the respect of various interactions and User Interface, however, it is requiring more demands from its users, and additional functions which cannot be provided by the Web Browser. It is required a new model for supplementary of the limitation of Web_based according to their customers' requirement, to enrich the good aspects of Client-Server System, and accept such various intricate requirements. It is X-Internet, which has born with these requirements. In this study, therefore, it will be suggested a productive development framework and a method to perform the project on Rich-Thin Client Platform of X-Internet Based.

Purpose This study analyzes whether Internet search of cryptocurrency has a causal relationship to return and volatility of cryptocurrency. Design/methodology/approach Google Trend was used as a measure of the level of Internet search, and the parametric tests of Granger causality in the 1st moment and the 2nd moment were adopted as the analysis method. We used Bitcoin's dollar-based price, which is the No. 1 market value among cryptocurrency. Findings The results showed that the Internet search measured by Google Trends has a causal relationship to cryptocurrency in both average and volatility, while there is a difference in causality and its degree according to the search area and category that Google Trend user should set. Because the Granger causality is based on the improvement of prediction, the analysis results of this study indicate that Internet search can be used as a leading indicator in predicting return and volatility of cryptocurrency.

In this paper, we propose a technique to represent a sheet music effectively on the Internet. For representing the Internet sheet music, this paper proposes the ScoreML(Score Markup Language) which is a new markup language based on XML, and describes the design of the XML DTD which defines the ScoreML. XML DTD constructing the ScoreML is designed to be able to represent various features of a sheet music in order to retrieve the real sheet music on the Internet. The sheet music built by the ScoreML is directly displayed on the Internet by ScoreML browser which is implemented in the form of Java applet.

The technology acceptance model(TAM) has been widely studied in IS research in order to gain a better understanding of the adoption and use of information systems. Based on the TAM, we explored acceptance of internet shopping mall. 261 questionaries were collected and analyzed. The results of this study showed that the internet shopping mall characteristics such as information quality, system design quality, and communication are important factors in affecting user's visiting and buying frequency at the internet shopping mall. Therefore, the internet shopping mall providers should make the product's information more informative and design shopping mall sites more effectively and interactively.

Conventional design producing systems using the Internet are largely classified into two groups: a basic type in which an operator of a design producing site receives an order for manufacture of a design from a purchaser, produces the design based on the content of the received order, and delivers the produced design to the purchaser; and a type in which a purchaser inspects given designs and select one of them for purchasing. Such conventional design producing systems have following problems. Firstly, receiving an order over the internet and delivering a produced design to a purchaser has nearly the same procedure as a conventional logo design procedure with the sole exception that an order can be received through the Internet. Therefore, the production of a design still costs a great deal and takes much time. Secondly, inspecting given designs, selecting one and producing the selected design is like simply selecting a picture, and thus a purchaser is not allowed to modify a design. To solve the above problems, it is an object of the present a new solution to provide a self-design producing system and method using network, in which a purchaser searches a design database for a design suitable for the purchaser's company, determines a design database by modifying design conditions, and makes an order for manufacture of a product to which the determined design is applied, through the Internet.

It is necessary to research on wireless position determination technology that enables location based services on Portable Internet. In this paper, I consider the position determination technology based on TDOA belong to trilateration method. That is using the difference of relative distance between base stations and terminal due to the time difference of arrival of downlink signal. In order to design the positioning server, This paper reviews the related research on current status of wireless position determination technology based on TDOA on Portable Internet. And then, it is suggested that system architecture, network interface, the calculation model for position determination, which are adapted to circumstance of portable Internet. Through this research on the positioning server, it is expected to guarantee that low cost and high efficiency of wireless positioning server on Portable Internet will be developed.

This study examined consumer responses of photos used in Internet shopping malls. The content analysis conducted a preliminary study of the top 100 online shopping malls to investigate current website practices. Stimuli based on the preliminary study. The present study was a $2{\times}2$ factorial design that evaluated two independent variables of product presentation and background. We analyzed 410 responses derived from the descriptive analysis, factor analysis, and covariance analysis through SPSS 20.0. The results showed that a product presentation was significantly different in attractiveness, informativeness, satisfaction, and repurchase intention after controlling apparel items and model. This product presentation in everyday life had greater mean values than product presentation with the posing model. The background had a significant mean difference in all consumer responses expect for attractiveness. Overall product presentation in everyday life and indoor cases were evaluated as most positive by the respondents. The findings provide practical implications for online shopping malls integrating product presentation.
