Recently, as the use of smart devices is becoming more common, various and convenient services are being developed. Among these services, the Social Network Service(SNS) is easily accessible anywhere, anytime. In particular, as well as sharing information, it forms a social relationship in cyberspace to expand new connections, and the SNS account is used as an authentication means of other services to provide users with speed and convenience at all times. However, despite the many advantages of SNS, due to security vulnerabilities occurring in the interworking process with various services, accidents of personal information are constantly occurring, and it is urgent to prepare countermeasures against potential risk factors. It is a necessary situation. Therefore, in this paper, the use of SNS is expected to increase rapidly in the future, and it is expected that it will be used as the basic data for developing the countermeasures by learning the countermeasures according to the security threats of the SNS.

This study is to analyze trends and relational structures in the energy sector related to renewable energy. For this reason, in this study, we focused on big data including SNS data. SNS utilizes the Instagram platform to collect renewable energy hash tags and use them as a word embedding method for big data analysis and social network analysis, and based on the results derived from this research, it will be used for the development of the renewable energy industry. It is expected that it can be utilized.

As social network service(SNS) has grown rapidly, the variety information being shared through SNS. However, the privacy of individuals can be violated due to the shared information through a SNS or the post written in the past at the SNS. Although, many researches concerned about it, they did not suggest key management and access control especially. In this paper, we propose the method for the protection of the message in SNS using access control and hash-chain.

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.

SNS는 온라인상에서 특정한 관심이나 활동을 공유하는 사람들 또는 불특정 타인과 관계망을 맺을 수 있는 서비스이다. 사회적 관계를 맺고 친분 관계를 유지해주는 SNS 서비스가 활발하게 이용되고 있는 반면에 SNS 사용자들에 대한 프라이버시가 노출되는 문제가 발생하고 있다. 따라서 본 논문에서는 SNS 환경에서의 프라이버시 보호를 위한 익명성 보장 방법에 대하여 제안한다. 본 제안사항은 사용자가 프라이버시 설정 단계를 통해 설정한 프라이버시에 따라 자신의 프로파일 정보 및 게시물 정보를 친구 또는 다른 사용자들이 확인하거나 익명성을 보장할 수 있다.

Social network service(SNS), provided by social network sites such as Facebook, Twitter and Cyworld is rapidly growing in online business. Furthermore, many companies have growing interests in finding effective ways to use SNSs for their innovations, marketing and advertisement. In fact, firms have recognized the utility value of the SNS for their business. In this aspect, this study attempts to identify key factors influencing the intention to continuous use of SNSs. Based on the UTAUT(the Unified Theory of Acceptance and Usage of Technology)model, this study proposes the research model, including the effects of social network service characteristics(social relationship support, information sharing, image expression) and individual characteristics(self-disclosure, extroversion, familiarity) on performance expectancy as well as the moderating effect of perceived information security among UTAUT variables. The 412T sets of data collected in a survey were tested against the modeling using SEM using SmartPLS. Results indicated that social network service and individual characteristics had significant effect on performance expectancy with exception of self-disclosure. In addition, the moderating effect of perceived information security had significant effect. The results had important implications for firms providing SNSs hoping to develop a successful business model.
