The popularity and adoption of smart-phones has greatly stimulated the spread of mobile malware, especially on the popular platforms such as Android. The fluidity of application markets complicate smart-phone security. There is a pressing need to develop effective solutions. Although recent efforts have shed light on particular security issues, there remains little insight into broader security characteristics of smart-phone application. Now, the analytical methods used mainly are the reverse engineering-based analysis and the sandbox-based analysis. Such methods are can be analyzed in detail. but, they take a lot of time and have a one-time payout. In this study, we develop a system to monitor that mobile application permissions at application update. We had to overcome a one-time analysis. This study is a service-based malware analysis, It will be based will be based on the mobile security study.

Use of mobile phones reached saturation point, the recent use of the iPhone, including the Smart Phone is increasing rapidly. How to extract forensic data from current mobile phones and SYN, JTAG, Revolving There are three ways. Mobile phone and Smart Phone, but the technology and how to use forensic data because of the difference must have different extraction methods. In this paper, in the Smart Phone will study how to extract forensic data. Commonly used in the Google Android Smart Phone and Windows Mobile Smart Phone OS in the specification and analysis for analysis, the data analysis. Also, Google Android and Windows Mobile Smart Phone to extract forensic data to generate evidence. The present study tested the Mobile Smart Phone technology research will contribute to the development of forensic techniques.

With increasing number of serious construction disasters such as death, a safety management in real-time is more required recently. One of the ways to support the needs, a convergence with Information Technology (IT) has been noticed. Although number of inefficiencies including a limitation of IT equipment (weight, control inconveniences) has been concerned, data exchanging and processing fields have been improved at a wide range with an advance of mobile communication and an introduction of smart mobiles that are simple and convenient. In this research, a framework is realized in connection with smart mobile to find the problems of current safety management and derive demands in order to support effective safety management. Two smart mobile applications, Safety Management application and Safety Guideline application, enable a real-time safety management and less re-work by provided safety information.

Nowadays, ubiquitous technology which combines sensors and network technology is emerging and it is called ubiquitous sensor network (USN). In this paper, mobile application for baby care using smart sensor is proposed. The proposed mobile application consists of mobile networks to transfer the information. It detects various information such as falling detecting, crying and fever detecting of infants. It keeps infants from external threats. The developed mobile application will be examined by simulation.

This paper proposes a method of a touch-based remote control and sensor information acquisition of a mobile robot using a smart phone. An application in a smart phone processes the acquired sensor information and conducts autonomous navigation. By touching the screen of the smart phone, a series of points obtained from designated curve traces are analyzed and provide control of a robot. This study develops a mobile application that acquires and handles data from a mobile robot and sends appropriate action commands through remote control using Bluetooth communication with a smart phone. The utility and performance of the proposed control scheme have been successfully verified through experimental tasks using an actual smart phone and a mobile robot.

Objective: The aim of this study is to propose the contactless gesture-based interface on smart mobile devices for especially rhythm action games. Background: Most existing approaches about interactions of smart mobile games are tab on the touch screen. However that way is such undesirable for someone or for sometimes, because of the disabled person, or the inconvenience that users need to touch/tab specific devices. Moreover more importantly, new interaction can derive new possibilities from stranded game genre. Method: In this paper, I present a smart mobile game with contactless gesture-based interaction and the interfaces using computer vision technology. Discovering the gestures which are easy to recognize and research of interaction system that fits to game on smart mobile device are conducted as previous studies. A combination between augmented reality technique and contactless gesture interaction is also tried. Results: The rhythm game allows a user to interact with smart mobile devices using hand gestures, without touching or tabbing the screen. Moreover users can feel fun in the game as other games. Conclusion: Evaluation results show that users make low failure numbers, and the game is able to recognize gestures with quite high precision in real time. Therefore the contactless gesture-based interaction has potentials to smart mobile game. Application: The results are applied to the commercial game application.

In the smart life era where the majority of economically active population uses mobile devices, smart devices have formed a new service market. In this study, we developed a shipyard quality management application using mobile devices such as smart phones and tablet PCs. For this purpose, the problems were derived through the analysis of the quality management work on shipyard and the considerations were extracted to build a smart work environment by analyzing the case studies of smart work in other industrial fields. Among the shipyard quality management work, functions thought to be highly utilized when converted to a mobile system has been developed as a mobile application. The application was developed by applying an object-oriented component-based development (ooCBD) methodology, and is expected to improve the user experience and the efficiency of quality management operations in shipyard.

Digital tourism is the digital support of the tourist experience before, during and after the tourist activity[1]. The GPS-enabled mobile phones provide location-based mobile applications such as tour guide and storytelling services. In this paper, we propose the smart tour guide service platform based on GIS and develop the mobile application to provide the smart tour guide service. The proposed smart tour guide service platform consists of CMS, the multi-modal navigation system, the tour attraction content creation and management system, the tour commodity creation and management system, the smart search system, and the user terminal. The smart tour guide application supports digital tourism in the pre-tour, during tour, and post-tour using the proposed smart tour guide service platform in the popular tourist attractions in Jeju.

With the development of computer technology, many different kinds of digital design tools have been developed and used. In the circumstance, methodologies of digital process have more been researched. Despite various atypical forms, there have been limits to the application and practical use of the mobile technology for approaches to the creation of architectural forms and various circumstances. Therefore, this study tries to analyze previous studies and actual conditions of mobile application in order to recognize the research necessity and suggest the possibility of the atypical form creation in the mobile environment. In short, the purpose of this study is to recognize the necessity of the smart mobile application for making idea & learning tools, suggest the process based selective application method (not analytical application) of smart mobile application technology to make possible atypical form creation in the initial step of architectural design processes, and propose a new method of mobile application.
