The purpose of this study is to explore the differentiated motivations of users of live commerce by focusing on the entry into untact consumption culture. In addition, we intend to verify the mediating effect of engagement in the relationship between the motivation and attitude of live commerce use. As for the research method, an online survey was conducted targeting live commerce users, and 245 valid samples were used for analysis. For data analysis, frequency analysis, exploratory factor analysis, reliability analysis, multiple regression analysis, and mediation regression analysis were performed. As a result of the analysis, the motivation for using live commerce was derived from four factors: Enjoyment of interaction, Substitutability of personal examination, Need for community, Trend setting. And Engagement was found to have a significant effect on attitude. Finally, engagement was found to have a partial mediating effect in the relationship between the motivation and attitude of live commerce use. The research results will provide implications for understanding non-face-to-face consumption culture and establishing effective strategies for the live commerce industry in the future.

Due to hardware resource limit and system incompatibility of the mobile device, and low bandwidth of wireless communication, there are a few difficulties in introducing the digital contract system based on wired communication to M-Commerce. To get over the difficulties, this paper defines a digital contract based upon XML and then addresses the design and implementation of M-XContract, a digital contract system for the mobile environment. M-XContract system has been constructed with the digital contract server, M-ESign module which contracts with the customer on the PDA and transfers the contract digitally signed to the server, M-EDecoder module which shows the contract to the customer from the server, and X-Auth which is a contract authoring tool. To evaluate the run-time performance of the M-XContract, we measured the digital signature generation time and transfer time to the server. The evaluation results show that the M-Xcontract is an efficient model for the mobile contract system.

As wireless network was developed and Capability of Wireless Phone was increased, M-Commerce was activates In Wireless network environment. User Authentication and Security in E-Commerce Environment is very important, so Authentication Technology, such as WPKI and Hermes System, XML Digital Signature in Wire Network is studying. But if authentication systems was implemented heterogeneous, WPKI is difficult to implement the system, it's not interoperate with authentication system on wire internet, not support XML digital Signature. Hermes system also not interoperate with XML digital signature system. So our paper designed System that can interoperate among digital signature systems and XML document to apply XML digital signature technology on wire network to wireless network, and then implemented system that can XML digital signature to use Java Card.

Live Commerce is rapidly emerging as a new paradigm for the digital economy and consumption activities in the post-COVID era. Many prior studies have been conducted on Live Commerce, but studies focusing on the characteristics of sources of Live Commerce are insufficient. This study aimed to investigate the human factors of sources that affect consumers' intention to use Live Commerce. For this purpose, based on an expanded TAM (Technology Acceptance Model) through literature research, variables were set, and a survey was conducted targeting Korean consumers who have experienced purchasing products through Live Commerce. Excluding unreliable data, 201 responses were utilized in the analysis of this study. At first, the measurement tools were checked through validity and reliability verification, and correlation analysis was conducted to identify the relationships between variables. Then, the proposed hypotheses were verified through multiple regression analysis. As a result, firstly, the human factors of sources had a positive effect on PU (Perceived Usefulness). Secondly, the PEOU (perceived ease of use) had a positive effect on both PU and CS (Consumer Satisfaction). Thirdly, PU had a positive effect on CS and ITU (Intention to Use). Finally, CS with Live Commerce had a positive effect on the ITU. Through this study, we try to provide an understanding of consumer behavior in the Live Commerce environment and contribute to enhancing the service provider's ability to offer high-quality Live Commerce content.

As cell phone and PDA have been in common use recently, there is a growing tendency to utilize the mobile terminals for M-Commerce. The information security and the receipt of e-trade are very important to support reliable digital transactions in wireless environment as in wired environment. Even though some work such as WML digital signature and WPKI has been studied for M-Commerce, there are several problems on the aspects of the functional limitation of the mobile terminals and the unsecure data transformation of WAP gateway. In this study we have designed and implemented a prototype system of issuing and verifying the electronic receipt that guarantees authentication, data integrity and non-repudiation for secure mobile e-commerce. Moreover, we have enhanced the system performance by letting the trusted independent server verify and manage the electronic receipt.

Ubiquitous electronic commerce can offer anytime, anywhere access to network and exchange convenient informations between individual and group, or between group and group. To use secure ubiquitous electronic commerce, it is essential for users to have digital signature with the properties of integrity and authentication. The digital signature for ubiquitous networks is required neither a trusted group manager, nor a setup procedure, nor a revocation procedure etc. because ubiquitous networks can construct or deconstruct groups anytime, anwhere as occasion demands. Therefore, this paper proposes a threshold ring signature as digital signature for secure ubiquitous electronic commerce using the ring signature without forgery (integrity) and the (n,t) ring signature solving the problem cannot prove the fact which a message is signed by other signer. Thus the proposed threshold ring signature is ubiquitous group signature for the next generation.
