In this paper, we propose a method to reduce mobile social network services (SNSs) traffic using a mobile integrated SNS gateway (MISG) to improve network communication performance between the mobile client and SNS servers. The gateway connects the client and SNS servers using the contents adapter and the web service adapter and helps to improve communication performance using its cache engine. An integrated SNS application, the user's client, communicates with the gateway server using integrated SNS protocol. In addition, the gateway can alert the client to new SNS contents because of the broker server implemented by the message queuing telemetry transport protocol. We design and develop the modules of the gateway server and the integrated SNS application. We then measure the performance of MISG in terms of content response time and describe the result of the experiment.

Purpose: This study was tried to investigate a structural relationship among key impacting factors and usage in SNS of government institutions. It was designed to research the processing property of SNS, the emotional property of SNS, and the service property of SNS for the SNS usage. Based on the research framework from the relationships among intrinsic SNS characteristics, social psychological characteristics, and the attitude of government institutions' SNS, the empirical research model and the hypotheses were established. Design/methodology/approach: Data for empirical study were collected from 453 of total distributed 500 by the structured questionnaire survey with SNS users of government institutions. The analysis was performed from effective 432 data, and the sample was mainly consisted of men, the thirty-old, and salesmen. Findings: The results showed that the emotional and service properties in intrinsic characteristics of SNS have a significantly positive effect to the value perception and the security variable in social psychological characteristics has a significant positive effects to the trust. Finally, the value perception has positive effects on both trust and use intention of government institutions' SNS. Meaning of these results is that intrinsic SNS characteristics, social psychological characteristics, and the attitude of government institutions' SNS have a significant effect on SNS usage.

Each online user should perform a separate registration and manage his ID and password for each online commerce or SNS service. Since a common secret is shared between the user and the SNS server, the server compromise induces the user privacy breach and financial loss. In this paper, it is considered that the user's authentication material is shared between multiple SNS servers for user authentication. A blockchain service architecture based on Hyperledger Fabric is proposed for each user to utilize an identical ID and OTP using the enhanced hash-chain-based OTP.

페이스북(Facebook)과 트위터(Twitter)등으로 각광 받는 소셜 네트워크 서비스(Social Network Service)는 사용자의 온라인과 오프라인에 구축된 인맥 네트워크를 기반으로 한다. SNS내의 소셜커머스, 소셜어플리케이션 등의 다양한 기능이 추가 되면서 새로운 온라인 서비스 시장이 등장하게 되었다. 초기의 새로운 가상 인맥 늘리기 수단으로 사용되었던 SNS서비스는 스마트폰의 등장과 카메라, 마이크 등의 추가 디바이스와 서비스간의 연계가 가능해 지면서 이용자들의 새로운 정보 생성과 실시간 커뮤니케이션이 가능해 졌다. 또한 SNS를 통한 정보의 흐름은 텍스트 기반의 한방향 정보 전달 틀에서 소리와 이미지, 동영상등의 다양한 미디어가 취합되는 공간이 됨으로서 사용자와 다른 사용자간의 상호 작용이 가능한 쌍방향 소통으로 현실의 정보를 보다 정확하고 빠르게 전달할 수 있는 하나의 미디어 형태로 진화하는 중이다. 본 논문에서는 소셜 서비스에서 생성된 정보가 집단 협업(Mass Collaboration)을 이룰 때 갖는 신뢰성을 기대하여 키워드 중심의 정보 형성에 따른 SNS 활용 방법을 제시한다.

The dramatic growth of social networking sites (SNS) has created a myriad of privacy concerns. Our study focuses on how much monetary incentive SNS users are willing to accept in exchange for disclosing their SNS information by accepting friend requests. First, we focused on information privacy in SNS, and estimated the value of information privacy by using the contingent valuation method. Second, we attempted to estimate how SNS users' willingness to accept would change when demographic information and additional information vary. Privacy-sensitive SNS users have the following characteristics: higher education, less SNS experience, and higher security consciousness. On the contrary, those who make good use of SNS and use open-based SNS are less sensitive to privacy. In summary, privacy-sensitive SNS users are fearful or uneasy when they have insufficient control of SNS information. Considering 14 conditions on the value of information privacy on SNS, the mean value of SNS information per person is 173,957 won. If we apply this value to Facebook users, the total Facebook information value would be 1.91 trillion won, considering that there are 11 million users in Korea.

The social networking service (SNS) is free, but the data usage fee paid to the telecommunications company and the member's information must be provided directly or indirectly. In addition, while SNS' specifications for transmitting and receiving devices such as smart-phones and PCs are increasing day by day, using universal transmission protocols in special environments such as contaminated areas or semiconductor manufacturing plants where work instructions are mainly made using short messages is not easy. It is not free and has a problem of weak security. This paper verified the practicality through the operation test by implementing IMCP, a low-power, low-cost message transmission protocol that aims to be wearable in special environments such as risk, pollution, and clean zone based on ATmega128.

This study aims to prevent the serious threat from dangerous person or group by responding or blocking or separating illegal activities by use of SNA: Social Network Analysis. SNA enables to identify the complex social relation of suspect and individuals in order to enhance the effectiveness and efficiency of investigation. SNS has rapidly developed and expanded without restriction of physical distance and geo-location for making new relation among people and sharing large amount of information. As rise of SNS(facebook and twitter) related crimes, terrorist group 'ISIS' has used their website for promotion of their activity and recruitment. The use of SNS costs relatively lower than other methods to achieve their goals so it has been widely used by terrorist groups. Since it has a significant ripple effect, it is imperative to stop their activity. Therefore, this study precisely describes criminal and terrorist activities on SNS and demonstrates how effectively detect, block and respond against their activities. Further study is also suggested.

Many people around the world and in the business environment changes is the emergence of social networks are bringing. And the rapid development of the idea, but are insignificant for the security threats that are used by many people in many companies, and social network services. In addition, although it is true that this connection is increased from the number of mobile machines to the development of M2M, that is not recognized for that vulnerability. To evaluate and identify vulnerabilities against security threats and countermeasures for the SNS access the social network on the M2M After looking for privacy and in the present.

This study explored the factors affecting the acceptance of public recording in SNS post. Using SPSS 21.0 program and AMOS 21.0 program, major results were derived through exploratory factor analysis, confirmatory factor analysis, correlation analysis, and path analysis. The results are as follows: First, the risk of personal information leakage on SNS posting has a significant negative impact on the attitude toward SNS posting. Second, the security of the SNS posting has a significant effect on the attitude toward the SNS posting. Third, the concern about privacy of SNS posting has a significant negative impact on the attitude toward SNS posting. Fourth, the attitude toward SNS posting has a significant effect on the intention to accept the SNS posting. The above results suggest that the SNS post recording should be able to collect opinions of SNS users from a long-term viewpoint.
