Along with the emerging mobile telecommunication¡@technology, mobile telecommunication industry has developed the different service from the traditional pronunciation communication. Applications of multimedia, data transmission and so on have changed people's life greatly. For consumer, the mobile phone is not only the telephone conversation machine, but also is one kind of drawing close to life tool, the status symbol. The demand of mobile device has transforms from the traditional functionality demand into the psychological stratification. They starts to care about what service the small mobile device serve. The border of telecommunication industry is also getting more and fuzzier. The 3G development is not into the expectation, the reason lacks the innovation application. But the software service has brings a revolution to the mobile telecommunication industry. This research is for the purpose of discussing how mobile service enterprise plans the suitable transport business pattern based on the user attitude. Base on the mobile portal, discusses the consumer to choose mobile service which factors to come under these factor influence and compared with two different case consumer's value localization.. The research result indicated that mobile service is restricted in mobile device the hardware characteristic and technology, but how to utilize innovates technology to promote attracts consumer's service, can be carries out mobile service the main consideration. By the software develops platform, not only the third party software developers cut the product price, also, because the platform has discussion's space, enables the consumer to be possible to talk directly with the developers and improve the software use greatly then easy.

The convergence of mobile commerce and internet technologies has promised users unprecedented convenience and greater enjoyment. Over the past few years, the development of mobile information and entertainment services (MIES) has been phenomenal. Recently, research has been conducted into ways toward better acceptance of these services by users. However, many of these studies are technical driven, without discussing important end user needs. To understand users' perception associated with mobile information and entertainment services the author extended and empirically tested a new antecedent model of Perceived Playfulness an intrinsic motivator toward technology acceptance by users, based on previous research. It has been shown that user's Perceived Playfulness toward information technologies has a direct impact on his/her subsequent use. Using the new antecedent model of Perceived Playfulness, the author argues users' Autotelic Personality, Perceived Service Quality, Perceived Technology Compatibility, their Motivation for Using and tolerance of Social Influence affect their Perceived Playfulness when interacting with MIES. A questionnaire was administered to students in business and computing schools at Auckland University of Technology. The closed-ended questions within the questionnaire were used to validate the proposed research model. The data were analyzed using Partial Least Squares. Most of the proposed hypotheses were supported, rendering several significant findings in this thesis. In this study, it has been found that individuals who are more innovative and confident about using MIES are more likely to develop a positive image toward these services. They also value services that are useful and easy to use and demonstrate high enthusiasm for more personalized mobile services. More importantly, their perceptions toward MIES can be further reinforced if their mobile phone functionalities are highly compatible with these services. Therefore, service providers should strive to create a seamless MIES experience for users. Furthermore, given that mobile phones have their own strengths and limitations, the motivation behind user's choices of various applications becomes an important issue for service providers to consider. It has been shown that the importance of service attributes vary with user's motivations of using MIES. This study therefore focuses on several important end user issues which are not well explored in the research of mobile internet services. Overall, this study contributed to existing research into user s perception toward MIES as an information technology based on his/her intrinsic motivator. Several important antecedents have been identified to influence user's Perceived Playfulness in this context. Limitations and suggestions for future studies are considered at the end of this thesis. Implications are also discussed.

The technological advances in wireless networks, smart phones, social networks, embedded sensor technologies and the wide spread of mobile devices have exposed customers to number of services. With these advanced technological innovations, computing capability and connectivity, customers look forward to get useful services and information by means of their mobile devices anywhere and at anytime thereby saving time and money. The importance of mobile commerce is increasing every day, since the mobile devices are becoming central part of our lives. One of the challenge here is the ability to reinforce the application behavior by utilizing context information. The analysis and utilization of context information is necessary to build intelligent applications and thereby focusing on less user attention by understanding the current situation. The information about the current location of a mobile customer, the time of request, and personal characteristics like nature of work, profession and economic status are utilized by applications to provide accurate context-aware services. Many of context-aware applications focus mainly on user activity, preferences which are not sufficient to provide context-aware intelligent services. However, there are few works in developing an integrated model for analyzing the context information. Many authors describe the context representation using five elements like who, what, where, when and how to provide a user centric view without emphasizing on the feature of generality and structural representation of context parameters. Since context information takes multiple forms, it is essential and necessary to make broad classification which helps application designers and developers to deal with possible contexts and their impact on application behavior. In addition, the context classification enables to understand complex customer situations due to changing mobile environment. Therefore, it is required to design a model which analyzes the context information of customers in a dynamic environment and hence, provide real time accurate service. The design and development of context-aware mobile commerce services requires a general conceptual model which can handle any type of context information for different applications. Due to the dynamic nature of business environment and also the customer preferences keep emerging, there is a need to develop business model which adapts to changing environment. To understand the current situation of customers in such highly dynamic environments and to enable the business transactions quickly among parties involved, it is essential to construct and analyze an integrated view of information from distinct sources. The adaptation of the provided services based on customer needs depends when the relevant context information is self-described in the form of beliefs. The observations made on combination of context information are deduced into beliefs as a result the decision making time to provide service reduces considerably. The aim of the thesis, is to design and develop a context-aware system which has been applied for mobile commerce environment by considering the customer context information. To do this, we have designed two models: the Context-Information, Observation and Belief (C-IOB)model and the commercial business model. The main function of C-IOB model is to support the application to identify a suitable context-aware service and to execute business transaction for a customer by analyzing the context information in the form of beliefs. We classify the used Context Information(CI)into four types: physical, system, application and social environment. The business model discusses the formal description of participants who are involved in commercial business. The C-IOB model The Context Information, Observation and Belief model deduces beliefs on customer, by combination of available context information during transaction execution or service provision. The beliefs represent the various situations of customers based on specific nature of the applications. The beliefs developed about an entity(e.g. ,person, place, thing) are primitive in most theories of decision making so that applications can use these beliefs to identify and execute context-aware services. The C-IOB model reduces the solution search space, since the knowledge about an entity is organized using cognitive factors, which maps user context information into real world observations and beliefs, as a result the decision making time by the system reduces considerably. The five CI -constructs: who, what, where, when and how enable many types of context information acquisition in our work. The commercial business model A commercial business model mainly involves the formal description of business participants who are involved in commercial business transactions. To meet the growing needs and to fulfill high expectations of customers, it is very important that application designers have to address the issue of building viable business models for commercial environment. The business model describes how an enterprise or an organization captures and delivers economical value to customers. In particular, the customers play major role in transactions execution and hence understanding and identifying the needs of customer is an important issue in building the business model for commercial purpose. Mobile Commerce Environment Mobile commerce environment (MCE) is one of the specific forms of commercial business model. It deals with transactions like purchases with the objective of supplying commodities like goods and services to customers using mobile devices. A Mobile commerce environment is established by considering set of customers, vendors and bankers, who are involved in commercial business activities like buying of electronic goods and services. The environment is based on certain factors like the type of customers, the type of transactions and the type of electronic products involved in purchasing. M-commerce is one of the most effective and useful ways of conducting business as the customers are constantly using mobile devices and it significantly assists customers in making transactions anywhere, anytime and thereby improving the customer satisfaction. C-IOB model based mobile commerce environment Mobile commerce applications are required to be flexible, in providing services due to inherent anytime and anywhere paradigm. The traditional systems during commercial business transactions, take large time to search the right product, which leads to more utilization of device resources like memory and computational power. In addition, the users are striked with more information which is not significant. Therefore, there is a need to design applications, which identify the customer requirements by acquiring the context information from distinct sources and thereby providing timely and specific information or services to the customer. Hence, to adapt services based on various situations, it is required to develop a systematic approach for representation and utilization of context information modified to special characteristics of mobile commerce applications. The mobile commerce environment uses C-IOB model for analyzing the relevant context information of customers and the context based beliefs helps to identify a suitable service for an end customer, thereby reducing mobile transaction execution time and providing customer benefits. The simulation environment consists of 10,000 electronic products which are categorized based on technical and commercial features. The simulation is carried out with ten mobile commerce transactions, the database consists of information about500 customers and 100vendors who deal with electronic products selling and10bankersfor money transactions. The customer context information is acquired from physical, system, application and social environment. When customers ends are quest for a service, the current context information is acquired, a set of observations is formulated and belief is deduced. The customer is provided with relevant information or service based on deduced belief. The simulation exhaustively tests the working of the system for mobile commerce transactions under different context environments. Some of the case studies are designed by applying the C-IOB model which includes placing the purchase order for the product, money transfer and after sales service. In summary, we have developed a context-aware system by using C-IOB model and also the design of commercial business model. To evaluate the performance of the system, we have incorporated context-awareness aspect for 10 business transactions applied to mobile commerce. The proposed system using C-IOB model provides customer required services as accurately as possible. The system has the capability to adapt to real time situation of customer needs, thereby enhancing the customer satisfaction. The simulation results have shown that the time to execute mobile commerce transactions is less using context based beliefs compared to context unaware approach. The accuracy of the system with belief based approach is higher than without context information. The customer benefits in business transaction are also enhanced by our design approach.

With the widespread usage of mobile devices and their applications, many areas of innovation have created a multitude of opportunities for mobile technologies to be deployed with very interesting effects. One such new area that emerged in the last few years is mobile commerce. It represents a system where various entities create real–life or digital assets, distribute information about them to interested consumers, execute transactions, accept various types of compensation methods, and finally deliver these assets; all of it in a secure and trusted manner, respecting users’ privacy. Since mobile devices are increasingly used for m-commerce, it is important to ensure that users’ data on such devices are kept secure. Mobile devices contain many of our personal and private data and information, since we nowadays use them for all kind of activities, both personal and professional. However, such data and information are not always treated in a secure and privacy friendly way. The goal of this thesis is to identify and provide solutions to security related problems found on mobile devices, such as communications, storage and mobile application design, and with the use of cryptocurrencies to combine the findings in the design of a secure mobile commerce system. As a result, this thesis describes a design and architecture of a secure e-commerce system, called eAgora, primarily exploiting mobile technology. The system is innovative as it treats digital goods, classified and called mobile commerce objects. Based on the attributes and anticipated use of such specific m–commerce objects, different security and privacy measures for each of them are needed and enforced. The goal was to design a system that deals with mobile commerce in a secure and privacy friendly way in all the lifecycle of the transactions. As users are mostly using mobile devices to connect to the proposed services, research first focused on mobile device security and privacy issues, such as insecure storage on the mobile device, insecure handling of user credentials and personal information, and insecure communications. Issues not only coming from the device itself but also from the nature of it; being mobile it is used in a different way that the classical desktop computers. Mobile devices are used in public, in an environment that cannot be controlled, and are interfacing a variety of networks that are not under the mobile device user’s control. Potential attackers’ interest was analysed in different mobile commerce scenarios in order to understand the needs for security enhancements. After having analyzed the possible threats, a methodology for mobile application development that would allow many common development errors to be avoided and security and privacy mechanisms to be considered by design was specified. Moreover, in order to provide secure storage and guard against active and passive intruder attacks, a secure Mobile Crypto Services Provider facility that allows storage of data on the UICC cards was designed and implemented. In order to secure communications, a secure e-mail application was designed and implemented. The application provides a user-friendly way to encrypt and sign e-mails, using the users’ already working e-mail accounts. The security functionality is completely transparent to users and ensures confidentiality and integrity of e-mail exchange. For the mobile commerce system, an architecture that enables exchange of m-commerce objects between different merchants, customers and retailers is proposed. Inthe architecture, policy enforcement and the feature to detect suspicious events that may be illegal and to cooperate with law enforcement was embedded. The newly defined technology of virtual currencies is used as a payment facilitator within the proposed architecture. Many of its innovative features are adopted but some are also extended, such as the secure use of the user wallet files, i.e. the files that link the user with the virtual currencies and enable payment transactions between customers and merchants. Although there is no distinction between different virtual currencies, Bitcoin is used as an example of a market valued trading currency to validate and evaluate the proposed secure e-commerce architecture and the findings have been applied on it. The thesis provides detailed use cases that demonstrate how the proposed architecture of eAgora functions in different complicated e-trading circumstances and how different security related mechanisms are used. The thesis concludes with the analysis of the research results and with proposed directions for future research and development works. / <p>QC 20150521</p>

台灣目前行動電話市場已趨向飽和，所以已經擁有了高普及率，那麼高使用率就是下一階段該努力的方向。而加值服務就是促使高使用量的關鍵。 加值服務讓行動電話從「耳朵的時代」轉變成「眼睛的時代」，不再只是接打電話的工具，而是可以下載電影、聽音樂，甚至行動電話不再是工具，而是個人代表。 行動商務的運用需要三個條件。基礎建設的創新、加值服務的應用與手持式裝置的成熟。基礎建設的創新是要讓無線網路的技術穩定、快速且全面無死角，才有辦法談到後續的加值服務。其次是加值服務的應用，加值服務的應用不需贅言，他會是加值應用服務的核心，其必須滿足使用者的需求才有意義。最後則是手持式裝置的成熟，其中包括顯示方式、大小及格式相容等問題。 在強調以人為本的現代社會，行動電話也將從人出發，滿足使用者的需求。所以Mobile 2.0就這樣出現。 所以本研究將以Mobile 2.0概念出發，研究未來行動商務的應用和可能發展的硬體裝置。 / The mobile communication market in Taiwan has reached saturation with cell phones being readily accessible. The focus for future development hence points to increasing the usage of such communication devices, and the key lies in the introduction of accessorial services. These accessorial services allowed telecommunication to evolve from the “age of hearing” to the “age of visualization”. Communication devices no longer serve to simply communicate, but also to download movies and to listen to music. They are no longer used as tools, but as a representation of the user. There are three factors involved in the application of telecommunication in business: infrastructure, accessorial services, and hardware installation. A well-established infrastructure involves a stable, efficient, and well-covered wireless network and enables the use of accessorial services. The application of accessorial services must fulfill the customer's needs. In addition, the installation of hardware must be well developed to be fully compatible between differences in size, graphics, formats, etc. With the modern society taking the idea of individualism as the center, communication devices will do the same to fulfill users' demands. This is the idea behind "Mobile 2.0." The study is based on the ideas of Mobile 2.0 to study future business applications and hardware accessories.

The purpose of this study is explaining the effect of trust on consumers mobile commerce adoption under the influence of cross-cultural effects in the tourism industry.  This research applied a quantitative method, with a total sample size of 200. The collected samples are coming from China and France in the tourism industry. The result of this study is in line with previous studies that trust plays a crucial role in mobile commerce(MC) adoption of consumers. Design, privacy and reputation are very important determinants of trust on MC adoption. This study shows that uncertainty avoidance(UA) has a negative impact on the relationship between trust and MC adoption, and the moderating effect of UA is weaker for the consumer who are accustomed to low UA culture, compared to those who are accustomed to high-level UA culture.

An increasing number of technologies and applications have begun to focus on mobile computing and the wireless Web as a way to conduct commerce-oriented transactions. M-commerce Websites that are usability friendly must emphasize information quality, system quality, and service quality, as these are proxy measures to mobile commerce user satisfaction (MCUS). Measureable variables can help researchers to understand how satisfaction induces users to return to a Website. Although several studies on m-commerce user satisfaction focus on content quality, appearance, service quality, and ease of use, the results of these studies were inconclusive because they do not address contextual usability barriers for the mobile Web. The task context, which consist of two activities, search and transaction, is a prominent contextual factor that affects mobile usability positively or negatively in achieving MCUS. The researcher determined what end user expectations and actual usage beliefs result in disconfirmation or MCUS. An empirical field study of an online retailer and search platform was conducted using a sampling of 98 participants. The participants used a smartphone to search and complete a transaction in the participant's natural setting. The study results indicated that expectations and usability measures including efficiency, errors, and flexibility significantly influence actual usage leading to MCUS. The original Expectation Confirmation Theory (ECT) model assumed that user's expectations could lead to actual usage. However, in the modified ECT model, it is the actual usage experience itself that determines MCUS. Disconfirmation is an inconsistent measure tied to actual usage, purchase intent, or satisfaction as mobile users often make purchases from m-commerce Websites because of convenience, flexibility, efficiency, and accessibility. If the user experiences an error during the search or transaction activity, such a drawback can cost a mobile Website future traffic, the loss of a transaction, and lead to lower levels of satisfaction.

Nowadays, we can get the wireless devices easily, such as cell phone, PDA, etc. It can make the life convenient. The P2P network which has been constructed by the wireless devices does not need the central server. They can communicate by themselves. Not only have protected in the privacy, but also add the convenience. The reason is that the devices are portable, we can get the newest information. Some P2P software focuses on the sharing. They can share files with other peer. The file can separate into several modes. The software will share these nodes. Every peer shares his own node, and it will speed up the rate of sharing. There are some selfish peers in this environment, and they will not want to share their own node. Moreover, some of them share the incorrect file. The software will solve this kind of problem by some mechanism. And it set some incentive mechanism to make the sharing to go on. Because the wireless devices are portable, we can use these devices for exchanging immediate information. Sharing the files is similar to the exchanging. Both of the users trust each other. They can exchange automatically. So, our research has designed a reputation based mechanism for exchanging. The users can evaluate each other to exchanging the information automatically. By this mechanism, the user in our system will exchange continuously. We can reach our purpose which makes the user in our environment can exchange automatically.

The convergence of traditional and electronic commerce practices is being driven by the need for businesses to keep up with the ever increasing competition of online retailing. This thesis aims to examine and analyze the possible benefits that may arise via the use and development of rapidly evolving mobile technology, through analyzing the benefits of each of the forms of commerce during outlined stages of retail process, in order to evaluate to what extend the benefits can be combined. The benefits of each form of commerce were studied by observing existing theories and validated as perceived benefits through consumer surveys and management interviews.The theoretical part of this thesis is based on academic literature in the subject of Traditional commerce, Electronic commerce and Mobile commerce. The empirical studies were conducted as both qualitative and quantitative research, with a consumer survey conducted with 350 students, as well as two interviews with managers of retail stores in Västerås, Sweden.Results of the analysis shows that Mobile commerce has a role to play in better combining the benefits of traditional and electronic commerce and results in a combined figure implementing the findings into a working model, which we have dubbed ‘the four I’s of commerce’. The results are aimed at aiding retail managers in determining whether or not to implement a revised business model including the aspect of mobile commerce.
