In order to analyze and maximize efficiency of advertise, business put more importance on SNS. Especially, keyword extraction analyses based on Hadoop receive attention. The existing keyword extraction analyses have mostly MapReduce processes. Due to that, it causes problems data base would not update in real time like SNS system. In this study, we indicate limitations of the existing model and suggest new model using Storm technique to analyze data in real time.

스마트 기기와 안드로이드 플랫폼의 급속한 보급은 모바일 애플리케이션들의 개발을 촉진하고 있으며, 게임, 소셜 네트워크 서비스 (SNS), 교육 등 다양한 도메인 분야에서 애플리케이션들이 개발되고 성공적인 사례도 발표되고 있다. 이동통신 칩과 결합된 GPS 수신기가 휴대폰 및 대부분의 스마트기기에 장착됨에 따라 위치 정보에 기반한 다양한 서비스가 활용되고 있다. 본 논문에서는 위치정보와 소셜 네트워크 서비스를 결합하여 가입자간 정보 공유 및 커뮤니케이션, 검색, 위치정보 등 다양한 비즈니스에 활용될 수 있는 위치기반 SNS 앱의 설계를 제안한다.

스마트 폰의 보급률이 증가함에 따라 시간과 공간의 제약 없이 의사소통이 가능한 SNS(Social Network Service)가 발달하고 있다. SNS는 기존의 단순한 의사소통에서 광고, 게임, 전자상거래 등 사회전반에 걸친 서비스로 확대되었다. 따라서 사용자에게 좀 더 효율적이고 유용한 서비스 제공이 가능하게 되었으며, 다양한 콘텐츠를 업로드 할 수 있다. 그러나 사용자의 지적재산인 해당 콘텐츠를 무단으로 다운로드 받을 경우 저작권에 침해를 받을 수 있다. 또한 악의적인 사용자의 불법 다운로드 경로를 파악하기 어렵다. 따라서 본 논문에서는 SNS환경에서 워터마킹 기술을 활용한 콘텐츠 저작권 보호 기법에 대해 제안한다. 제안하는 기법은 사용자의 SNS 계정에 업로드한 콘텐츠의 저작권을 보호하며, 악의적인 사용자의 불법 다운로드 경로를 추적하여 추가적인 불법행위를 방지할 수 있다.

Along with the recent advances of mobile internet technology, use of social network service(SNS) is very common among adolescents or college students in their daily lives. Although there have been a lot of studies on Internet addiction or mobile phone addiction, however, there were little research on SNS addiction so far. Scholars investigated somewhat broader and obscure phenomenon of Internet addiction. In this regard, the current study tried to examine factors which influence SNS addiction behavior. Unlike Internet addiction, there are positive influencing factors such socialization, enjoyment as well as problematic ones like loneliness. Data were collected from college students in Korea to examine how those factors influence addiction behavior and hypotheses were tested using the partial least square method. All three factors, socialization, enjoyment, and loneliness, were found to significantly influence SNS addiction and socialization was positively associated with enjoyment.

Steganography is an advanced technique that hides secret messages by transforming them into subtle noise and spreading them within multimedia files such as images, video and audio. This technology has been exploited in a variety of espionage and cyber attacks. SNS messenger is an attractive SNS Service platform for sending and receiving multimedia files, which is the main medium of steganography. In this study, we proposed two noble steganography communication techniques that guarantee the complete reception rate through the use of thumbnail images in the SNS messenger environment. In addition, the feasibility was verified through implementation and testing of the proposed techniques in a real environment using KakaoTalk, a representative SNS messenger in south korea. By proposing new steganography methods in this study, we re-evaluate the risk of the steganography methods and promoted follow-up studies on the corresponding defense techniques.

As Internet technology develops, SNS users are increasing. As SNS becomes popular, SNS-type crimes using the influence and anonymity of social networks are increasing day by day. In this paper, we propose a fake account classification method that applies machine learning and deep learning to statistical and image data for fake accounts classification. SNS account data used for training was collected by itself, and the collected data is based on statistical data and image data. In the case of statistical data, machine learning and multi-layer perceptron were employed to train. Furthermore in the case of image data, a convolutional neural network (CNN) was utilized. Accordingly, it was confirmed that the overall performance of account classification was significantly meaningful.

Due to the vitalization of the smart phones, mobile revolution has been started. The mobile revolution has elevated SNS service, which was once considered as just one of many communication tools, to the single most important communication method as well as diffusion of social commerce. Yet, there has not been an adequate study of the roles of SNS in the domestic social commerce market, which has gotten a lot of spotlights. Therefore, the purpose of this study is to investigate the influence of various characteristics of social commerce that it has an impact on the purchase intension as well as the moderating effects of SNS. For these purposes, this study has drawn up the characteristics of social commerce in cost cutting, impulse buy, social influence, decision support, word of mouth effect and etc. to prove the interaction effect of SNS. The regression analysis showed that the characteristics of all the social commerce are related to the dependent variable. As a result of drawing up the interaction effect of SNS, it has shown that the cost cutting and word of mouth have significant influence in the social commerce diffusion as the usage of SNS increased. In conclusion, the main implication of this study is to provide the basic grounds for social commerce business strategy as it investigated the characteristics of SNS and its relation.

With the advent of SNS (Social Network Services), the product reviews by friends in SNS are intensively utilized for online marketing. However, there is a lack of empirical evidence on the actual marketing effect of SNS reviews, although we need to identify who can be the target of SNS marketing in terms of customer attributes, preferences, or experiences. In this study, we investigate the moderating role of customer attributes in identifying the effect of SNS reviews on customer purchasing decision. As the moderating variables, we adopt 'information search experience' and 'perception of information overload'. Research results evidence that, in order to understand the effect of SNS reviews in a comprehensive manner, we need to examine it in the context of various related factors such as 'information search experience' and 'perception of information overload'. The results show that the persuading effect of SNS reviews for product purchasing is stronger for the customers with the lower information search experiences as well as the lower perception on the information overload on the web. This result delivers managerial implications on who can be the target customers of SNS marketing.

The present study explored the moderating roles of perceived responsiveness of SNS friends and self-esteem in the relationship between SNS use and perceived social support among college students. Using a panel owned by a research firm, a nationwide online survey was conducted (females N = 264, males N = 239). The results of regression analysis suggested that there is no significant main effect of SNS use but a significant main effect of perceived responsiveness of SNS friends. In addition, a three-way interaction effect was found among perceived responsiveness of SNS friends, SNS use, and self-esteem. This study contributes to elaboration of the extant research as well as providing practical implications to SNS-based intervention programs for college students' psychological well-being.
