Rapidly developing mobile internet technology and extensive service of smart phones have led to growing use of mobile applications. It is natural that software developers and IT-related students develop a variety of applications that can be used for everyday life. The present paper reports a case of developing such an application that was developed in a capstone design course of Department of Computer Science at Namseoul University. This so-called 'Application for Prevention of Loss of One's Belongings' was designed to let students learn a set of tools based on Android operation system. This app can prevent smart phone users from losing their belongings using an alarm. The educational effect from the process of developing this application is also discussed.

WebView is a vital component in smartphone platforms like Android, Windows and iOS that enables smartphone applications (apps) to embed a simple yet powerful web browser inside them. WebView not only provides the same functionalities as web browser, it, more importantly, enables a rich interaction between apps and webpages loaded inside the WebView. However, the design and the features of WebView lays path to tamper the sandbox protection mechanism implemented by browsers. As a consequence, malicious attacks can be launched either against the apps or by the apps through the exploitation of WebView APIs. This paper presents a critical attack called Supplementary Event-Listener Injection (SEI) attack which adds auxiliary event listeners, for executing malicious activities, on the HTML elements in the webpage loaded by the WebView via JavaScript Injection. This paper also proposes an automated static analysis system for analyzing WebView embedded apps to classify the kind of vulnerability possessed by them and a solution for the mitigation of the attack.

Interactive-typed devices and contents that have been often applied in the field of entertainment and game are the technology that allows you to maximize the enjoyment and participation of users through the interaction of each. In this paper, we designed an interactive-typed smartphone app that is based on the Android platform, implemented the wearable Bluetooth device to control via a interactive interface with a vibration sensor and three-axis acceleration sensor. We tested the functionality and 3-axis motion's operability by using smartphone app, interface interactive-typed device that has been developed, prove useful as a wearable Bluetooth device that has the convenience of the user. Further, it is shown that by implementing the optimized protocol of the sensor data transfer over Bluetooth, it is possible to reduce the malfunction of the content of the smart phone.

In this paper, it suggested Android smart phone application for users who want to find valley at summer. To provide correct information, we used Korea Tourism Organization's tourism information database and to provide tourism information and map service at once we linked Naver map. Search valley application can search valley by using country's region name and keyword by using map and GPS. we can find restaurants accomodations around your location. we can get restaurants and accommodations by control distance so we can get phone number, pictures and detail information about searched data. Also, you can bookmark valley where you want to go and you can search of delete bookmarked valley whenever you want. you can share opinion by writing postscribe about the valley where application user went. for developer and users amicable communication we made Q&A board.

스마트폰으로 무선게임을 이용하는 인원이 가입자의 증가로 1,000만 시대에 돌입하였고 2015년까지 연평균 무선게임 증가율을 32%에 달할 것으로 예견된다. 이에 본 연구에서는 착시현상을 이용한 스마트폰 게임을 개발하여 스마트폰 이용자들이 휴식시간에 기분전환으로 본 게임을 사용하도록 개발하였다. 본 개발은 사용자의 감정상태 종류별로 메뉴를 설정해 두어 해당 감정을 전환하는 기능을 추가할 수도 있으며, 여러 사람들과 착시되는 대상을 찾는 놀이로 활용 가능하다. 착시현상을 보는 중 시간을 측정하는 기능을 추가한다면 게임의 기능을 한층 높일 수 있다.

This paper proposed image matching technique that find out the truth of the wild ginseng through smart phone when the common person discovered a plant like a wild ginseng. Also sharing a location and information by SNS, we can improve the probability of wild ginseng discovery. Image matching technique using OpenCV porting in android finds out the truth of the wild ginseng with comparing existing it. Thus we are able to compare and analysis them in our application program. For more verification, we added marking function of wild ginseng position for information sharing between users.

This study is about developing an Android application that provides information on customized styling and the app was made to offer assistance in coordinating users' clothing. It keeps the record on clothing items users wore and uses it as coordination information, and prepares styling by referring to user-specific clothing management data. The photos can taken during shopping or can be taken from smart phone gallery, and the images searched through Daum OpenAPI can be saves in the app. Using the saved photos of items and clothes that were previously worn, the app provides styling recommendations.

Smartphone is very useful for use in the real life through the improvement of computing power, faster data rate and the variety of applications. On the other hand, using the smartphone has been exposed to a lot of crime. Also, it occurs attempting to delete a data of smartphone memory by anti-forensic tools. In this paper, we investigate and analyze the anti-forensic tools used in the Android smartphone to study the characteristics and techniques of anti-forensic tools. In addition, experiments are performed to validate the availability of anti-forensic tools by the Oxygen Forensic Suite that is a commercial forensic tool.
