Abstract With the development of ubiquitous computing technology, users are using mobile devices which are for producing and accessing information. Due to the limited computing capability and storage, however, mobile cloud computing technology are emerging research issues in the architecture, design, and implementation. This paper proposes the trust management approach by analyzing user behavioral patterns for reliable mobile cloud computing. For this, we suggest a method to quantify a one-dimensional trusting relation based on the analysis of telephone call data from mobile devices. After that, we integrate inter-user trust relationship in mobile cloud environment. As a result, trustworthiness of data in data production, management, overall application, is enhanced.

1 Introduction Cloud Computing is a method in which users access various computing resources and computing power of their own in a network environment [1–3]. Tasks are performed efficiently

and economically via outside infrastructure. It could realize that the users can access the data wherever and whenever they want [4]. Cloud computing technology is transferred from previous distributed computing technology such as grid computing and utility computing [8] (Fig. 1). The cloud computing service has been incorporated in various areas as the technology of virtualization and network environment have become sophisticated. Not only that, as the web technology has evolved to collective intelligence, cloud computing has been lauded as one that suits the needs of the web 2.0 paradigm [5, 6]. In addition, mobile devices such as smartphones and tablets have become sophisticated enough to replace conventional computing devices that they are currently accepted as an important part of everyday life [7]. Users are now able to acquire and produce various kinds of information and data using diverse mobile applications and the web in wireless network environment wherever and whenever they want. This has led to production of more information, yet the storage and computing solutions have not developed in tandem, which calls for adoption of mobile computing [9]. Mobile clients share their roles within their cloud via outsourcing, thereby increasing the overall efficiency of the process being carried out. Establishing a cloud environment with resources in smartphones is a representative case of mobile cloud computing [10]. Each mobil
