Recently, mobile commerce is widely spread around the world according to fast growth of the mobile communication market. The existing digital document is not well fit in mobile commerce because of weakness of the hardware of mobile devices, low bandwidth of wireless communication, and the constraints of the size and resolution of the display. In this paper, we analyzed the elements of the digital document proper for mobile commerce based on wireless communication, designed the XML form for the digital document, and implemented the X-Auth which is an authoring tool for the XML digital document. X-Auth does not require that the author or user know XML. And also it makes it possible to create the digital document fit for the size of the mobile device display and therefore remove inconvenience due to the scrolls.

The rapid growth of mobile communication technology has provided the expansion of mobile internet services, particularly mobile commerce takes much weight among them. Even though current mobile commerce service has serious problems which check its development, such as limited contents, expensive charge system and hardware restriction of mobile device, it is strongly expected as one of the next generation Internet services. In this paper, we summarize the problems like above and provide some total solution to meet them as follows: a function for automatic gathering of product information on online Internet and automatic translation it to data for mobile commerce, a middlelet application which provides functions for product search and order on the mobile device through off-line processing, and a function of user adaptive recommendation. We have actually designed and implemented the proposed system and verified the functions and effectiveness of the system.

Electronic commerce that use Mobile Phone according as the radio Internet develops rapidly and performance of Mobile Phone develops is activated. It is said that electronic commerce that use these Mobile Phone is M-Commerce. Also, the most important controversial point is data security or an user certification technology at these electronic commerce, there are research reactor WPKI and WTLS about this technology. However, when transmit message again after sign electronic documents in Mobile Phone, if do not encrypt, danger exists to be exposed to outside. Therefore, in this paper, designed system to encipher document that handle and handles user certification applying XML electronic sign technique in Mobile environment. Prevent of XML electronic sign in Mobile environment through this paper, and can stave off danger from outside by enciphering electronic sign document.

인터넷은 21세기 산업발전의 원동력이며, 인류 역사상 가장 빠른 속도로 확산된 미디어로서 현재 인터넷 비즈니스는 유통은 물론 금융, 주식거래, 경매, 오락, 택배 서비스 등 산업 전반으로 빠르게 확산되고 있다. 빠른 환경변화와 더불어 다양한 인터넷 사업 모델이 계속 새로 등장하고 있으며, 그 중 전자상거래는 더 이상 새로운 기술이 아닌 우리 환경의 필수적인 요소로 자리잡고 있다. 현재 모바일 전자상거래는 시장 형성의 초기 단계로 무선 인터넷 시장의 상황과 수익 창출의 관점에서 볼 때는 무선 인터넷 포탈 서비스의 핵심이 될 것이다. 이러한 요구에 부응하기 위하여 본 논문에서는 전자상거래를 위한 시스템을 UML (Unified Modeling Language)로 설계하여 시스템의 특성에 맞게 사용자가 시스템을 사용할 수 있도록 한다.

This study investigates the differences between IT workers, who possess a high understanding of technology, and non-IT workers in the resistance to accepting an innovative service like mobile commerce. From a total of 317 survey respondents, the results of the study revealed that perceived risk, compatability, and complexity were the significant factors for resistance to mobile commerce for IT workers, while relative advantage, compatibility, and complexity were the factors of resistance for non-IT workers. Higher innovation resistance was shown to result in lower intention of use for both groups of mobile commerce users.

모바일 통신의 수요가 증가하면서 유선상에서의 상거래 형태가 무선으로 변화하고 있다. 무선 매체를 통한 지불 형태가 다양화되고 있으며 무선 거래의 이용률도 증가하고 있는 추세이다. 그러나 무선 통신은 유선 통신에 비하여 보안적 측면에서 공격의 대상이 되기 쉽다. 따라서 본 논문에서는 무선 통신 상에서의 안전한 전자상거래를 위하여 USIM을 이용한 지불 솔루션을 제안한다. USIM은 모바일 기기에 내장되는 스마트 카드 형태의 개인 인중 정보를 저장할 수 있는 모듈로서, 추가적으로 전자화폐의 기능을 담당한다. 제안한 솔루션의 유용성을 증명하기 위하여 Java 기반의 USIM을 이용하여 J2ME 환경상에서 전자화폐 시스템을 구현하였다.
