In this paper, the pattern of extracting the same expression is proposed by using the Android intelligent device to identify the facial expression. The understanding and expression of expression are very important to human computer interaction, and the technology to identify human expressions is very popular. Instead of searching for the emoticons that users often use, you can identify facial expressions with acamera, which is a useful technique that can be used now. This thesis puts forward the technology of the third data is available on the website of the set, use the content to improve the infrastructure of the facial expression recognition accuracy, in order to improve the synthesis of neural network algorithm, making the facial expression recognition model, the user's facial expressions and similar e xpressions, reached 66%.It doesn't need to search for emoticons. If you use the camera to recognize the expression, itwill appear emoticons immediately. So this service is the emoticons used when people send messages to others, and it can feel a lot of convenience. In countless emoticons, there is no need to find emoticons, which is an increasing trend in deep learning. So we need to use more suitable algorithm for expression recognition, and then improve accuracy.

Nowadays, smart devices are the target of the digital forensic investigation. Among various smart devices, we can obtain much information from smart phone which is provided with continuous power and used for data communication. This paper deals with the traces to be left in Android smart phones after using the navigation applications with the GPS function. We selected navigation applications(domestic and overseas) which have a high number of download times, anaylzed them and discussed the meaning of the analysis result in digital forensic investigation.

This study makes a proposal about Flash mobile game applications using Adobe AIR. In developing a mobile game, the developer programs in Flash ActionScript, and distributes and publishes the program using Adobe AIR so that the game can be played on an Android mobile device. In order to run the game, the player downloads and installs Android Adobe AIR onto the mobile device and sets up the published app. This study designed and implemented a mobile game application and showed that a mobile game is executed on a smart phone. This outcome may be applicable to various genres of apps. Moreover, this study analyzed the trends of mobile games, focusing on their genres and characteristics, and according to the results, most of them were mobile games using Kakao Talk. The analysis results also showed that the popularity ranking of games varied little among sites.

This proposed project is about a bicycle anti theft devised system which helps people protect the bicycle from theft and helps to track the stolen bicycle's location using a smart phone. Safety bike uses two main devices to keep the bicycle secured, the vibration sensor and GPS sensor. The purpose of this project is to put all these small devices into one well connected system which will help the bicycle owner have more control over the security of his own bicycle. The whole system can be divided into two main parts. The first part is about the hardware development whereby all electronics components are connected via the circuit design using wire wrapping technique. This hardware part includes, a vibrations sensor, a GPS receiver, a toggle switch, LED light, Bluetooth and a buzzer. Wireless Bluetooth signals are used as the means of communication between the smartphone and the microcontroller. The second part is the software part which is being to program and control the whole system. The program is written using MikroBasic, a full-featured Basic compiler for microcontroller based systems. In conclusion, this system is designed to enable user to have control in securing his/her bicycle also being able to find and locate it at any time using GPS receiver and mobile android application.

Mobile directory has offered just the same function until now, SNS service also has offered for our to meet other people and liaise between person and person. But it has a important thing which can not offer direct to liaise between person and person. In this paper, we has developed the "SNS Consolidation Directory" for solve the problem which needs to modern people with. A main purpose of SNS Consolidation Directory will develop the smart directory which offer to improve SNS service and personal relation supervision. This system function has initial search, anniversary, birthday alarm, using the UI contact frequency, SNS service and directory exchange.

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.

This study can read register reviews and search read information that users want by musical, drama and movie by using DB by developing App providing the newest culture view and information in android smart phone, when users want to enjoy cultural life. Also, the administrator logins as Administrator-mode and controls cultural information and makes smooth controlling by identifying user's information. In addition, the user logins as User-mode and reads cultural information and can make possible in reading and writing reviews. It makes possible to enjoy leisure activity as cultural activity by identifying reliable performance information via recommendation of friend groups.

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.
