The importance of marketing on mobile platforms as well as mobile commerce is increasing dramatically in fashion industry. The purpose of this study was to categorize mobile fashion marketing strategies and to examine application usage motivations that influence brand attitude, purchase decisions, and post-purchase evaluation. Qualitative research methods, in particular focus-groups and in-depth interviews, were conducted to examine the typology of mobile marketing and fashion application usage motivations. Then, a modified survey was used to quantitatively examine what content consumers expect from fashion applications. Results of the qualitative study indicated that consumers perceive sensory (visual, tactile, auditory), relationship, information and practical marketing strategies through motives. Survey result from 229 consumers revealed four fashion application usage motives: sensory, relationship, information and practical. Based on these motives consumers were segmented into three groups: the experience/relationship-conscious, the product information-conscious, and the lifestyle information-conscious. The product information-conscious group showed higher level of monthly income and clothing expenses but lower level of mobile device usages. Lifestyle information-conscious group and experience/relationship-conscious group had higher level of attitude, and post-purchase evaluation. It was experience-relationship conscious consumers who spent more time in mobile use. This study shows a better understanding of mobile marketing environment of fashion applications.

This paper illustrates the competition between the mobile pay and credit card systems by utilizing the theory of two-sided markets. Two firms, as platforms, maximize the profit collecting fees from consumers on one side and from retailers on the other side. Consumers pay to buy goods and services with mobile pay, credit card, or cash. The basic model is one that each platform maximizes its profit. We show that the fees for credit card holders and retailers are higher than the respective costs. The fee for retailers of the mobile payment is higher than its cost, while the buyer's fee may be higher or lower than its cost. Applied model is the one that employs the delegation game model. The total profit of the mobile pay system is composed of its profit and the weighted demand for the mobile pay. It is shown that buyers' fee under the applied model is lower than that under the basic model, resulting in an increase of the demand for the mobile pay. The fee for the retailers rises, albeit the sum of fees for the buyers and retailers falls. The profit for the mobile pay system is increased, while that for the credit card company stays the same.

Mobile payment services are evolving into a variety of integrated platforms that greatly affect the lives of consumers. In addition, the importance of mobile payment services is being used as a means of payment in cross-border e-commerce. Accordingly, although a number of related studies have been conducted, most of the studies are based on the technology acceptance model. This study analyzes consumer acceptance intention of mobile payment services by applying consumption value theory. Four dimensions were derived from the theory of consumption value: functional value, emotional value, social value and situational value. With this, we identified the impact on consumer acceptance of mobile payment services. The analysis was performed using a structural equation model. Researchers collected 300 copies of the questionnaire from Chinese consumers and used it for analysis. Empirical analysis shows that functional value, emotional value, social value and situational value are all increasing consumers' willingness to accept mobile payment services. In addition, only social values were showing differences in their influence on the acceptance of mobile payment services with age. This study contributes to the development of the relevant field in that few studies describe mobile payment services by applying consumption value theory.

In this paper, we design a mobile phone based remote control system for PC using SKT WPAN platform and compare the presented platform with that of Windows Mobile. The usability of WPAN is one of the main issues which should be considered for the ubiquitous services. For easy development and easy use of the WPAN applications, SKT WPAN platform provides abstract WPAN APIs and WPAN Application Manager for ubiquitous services. In this paper, we implement a remote control application using the WPAN platform and show the validity of the platform comparing with other platforms. In the implemented application, we use WPAN abstract APIs on the mobile phone side and a general Bluetooth APIs on the PC for a connection between phone and PC. Through the implementation and comparison, we show that the WPAN application can be easily developed with WPAN platform.

This paper presents compact cryptographic hardware architecture suitable for the Mobile Trusted Module (MTM) that requires low-area and low-power characteristics. The built-in cryptographic engine in the MTM is one of the most important circuit blocks and contributes to the performance of the whole platform because it is used as the key primitive supporting digital signature, platform integrity and command authentication. Unlike personal computers, mobile platforms have very stringent limitations with respect to available power, physical circuit area, and cost. Therefore special architecture and design methods for a compact cryptographic hardware module are required. The proposed cryptographic hardware has a chip area of 38K gates for RSA and 12.4K gates for unified SHA-1 and SHA-256 respectively on a 0.25um CMOS process. The current consumption of the proposed cryptographic hardware consumes at most 3.96mA for RSA and 2.16mA for SHA computations under the 25MHz.

Middleware for mobile devices, embedded middleware, is used for mobile devices, cellular phone and DMB related services. It is essential for middleware providers to provide high quality middleware in conformity with its standard and interoperability on hardware platforms. The standard conformance and interoperability of embedded middleware are the key factors to make service providers succeed in their business. The quality of embedded middleware could be secured when Tests for the standard conformance and interoperability of embedded middleware are performed with well established test framework. In this paper, we describe middleware testing methodology of standard conformance, interoperability and middleware test framework for mobile devices.

In existing mobile computing environments, users need to choose between their privacy and the services that they can receive from an application. However, existing mobile platforms do not allow users to perform such trade-offs in a fine-grained manner. In this study, we investigate whether users can effectively make utility-privacy trade-offs when they are provided with a multilevel privacy control method that allows them to recognize the different quality of service that they will receive from an application by limiting the disclosure of their private information in multiple levels. We designed a research model to observe users' utility-privacy trade-offs in accordance with the privacy control methods and other factors such as the trustworthiness of an application, quality level of private information, and users' privacy preferences. We conducted a user survey with 516 participants and found that, compared with the existing binary privacy controls, both the service utility and the privacy protection levels were significantly increased when the users used the multilevel privacy control method.
