Abstract. The purpose of this study is to develop and present security assessment models to manage the quality of Web² mobile environments. Web² is an evolved concept of web from Web 1.0 and Web 2.0 which means, diverse services and technologies including Real-time service, Social Network Services, Augmented Reality technology and Location Based Service are realized in mobile environment. However, compared to Web 1.0 and Web 2.0, few studies have been conducted for the security issues of Web² mobile environment. To be prepared for such issues, this paper reviews the characteristics of security in Web² mobile environments and present security assessment models in perspectives of Sensor-generated threats and Usergenerated threats. This study is significant in that it presents the directionality of the security issues to be discussed later in Web² mobile environments. This study will have implications for businesses and researchers preparing Web² mobile services and marketing.Keywords: Web² Mobile Environment, Security Assessment, Sensor-generated Threats, User-generated Threats IntroductionRecently, the development of mobile network infrastructures, mobile communication technologies, and terminal technologies; the advent of diverse applications; and the activation of application markets have led the global increases in the supply and use of smart phones. That is, with the evolution of mobile Internet networks such as WiFi and 3G that enable users to freely access and use the Internet anytime and anywhere; the upgrading of the performance of smart phones into all-in-one devices that enable document works and support replays of diverse multimedia; the advent of diverse applications that satisfy users' needs; the development of an operating system (OS) that supports the applications; and the activation of application markets where those applications can be bought and sold, smart phones are providing new opportunities for businesses and revenue creation in the saturated mobile market, where it has become difficult to create revenues with voice services [1]. However, diverse factors
The purpose of this study is to investigate the impact of the activities for KM on the knowledge sharing through the social networking and digital networking. The research conducted a survey and analyzed the level of the social and digital networking, and identified the relationships with the factors of KM activities, and the knowledge sharing. As the results, the findings illustrate that the managers focused on digital networking based on IS for knowledge sharing. In contrast, for the employees, they mainly focused on social networking. Moreover, as a result of that all the social and digital networking are positive effect on the knowledge sharing, it is need to establish strategies for knowledge sharing through social networking in their organizations.
