정보기술의 활용이 보편화되면서 대중과 연구자 모두 정보 프라이버시 문제에 대한 관심이 높아지고 있다. 이러한 문제에 대한 연구가 기하급수적으로 증가하면서 연구결과에 대한 전반적인 이해가 어려워졌다. 이에 따라 과거연구에 대한 체계적인 검토가 요구된다. 본 연구는 정보 프라이버시 연구에 핵심적인 네 가지 연구개념을 두 가지 연구모형으로 설정하고 기존 연구에서 수집된 데이터를 이용하여 실증 분석하였다. TSSEM이라는 정량적 메타분석 기법이 적용되었는데, 이 기법은 MASEM의 한 가지로서 구조방정식모형과 메타분석 기법을 통합하여 분석하는 기능을 제공한다. 분석결과는 위험 중심적 모형이 염려 중심적 모형과 비교하여 보다 높은 모형 적합도를 나타내었다. 본 연구의 결과는 전통적인 염려 중심적 모형의 설명력에 의문을 제시하며, 사용자의 프라이버시 정보 제공의도를 설명하기 위하여 위험 중심적 모형을 고려할 필요가 있다는 점을 시사한다.

Internet-based distribution of digital contents provides great opportunities for producers, distributors and consumers, but it may seriously threaten users' privacy. The Digital Rights Management (DRM) systems which one of the major issues, concern the protection of the ownership/copyright of digital content. However, the most recent DRM systems do not support the protection of the user's personal information. This paper examines the lack of privacy in DRM systems. We describe a privacy policy and user's privacy preferences model that protect each user's personal information from privacy violation by DRM systems. We allow DRM privacy agent to automatically negotiate between the DRM system policy and user's privacy preferences to be disclosed on behalf of the user. We propose an effective negotiation algorithm for the DRM system. Privacy rules are created following the negotiation process to control access of the user's personal information in the DRM system. The proposed privacy negotiation algorithm can be adapted appropriately to the existing DRM systems to solve the privacy problem effectively.

LBS(Location-Based Service) is one of the smartphone application services which has been receiving great attention recently. Various applications of smartphone use LBS to provide innovative services. However, use of LBS raises privacy concerns because the location information of users is constantly exposed. Privacy calculus perspective attempts to understand the characteristics of the user's privacy. It is based on the risk-benefit analysis in the economics' perspective. That is, when the benefit expected through personal information disclosure is higher than risk, we are willing to provide personal information. This research suggested a research model based on the privacy calculus perspective to clarify the effect of information disclosure intention of smartphone LBS application users. Based on the main factors of privacy calculus, perception of privacy risk and privacy benefit, the relationship of the perceived value and the information disclosure intention was empirically analyzed by utilizing structural equation modeling(SEM) methodology. According to the results of the empirical analysis, it was found that all relations have statistically significant explanatory power except the relation between privacy concern and information disclosure intention. This study showed a strong evidence of antecedent factors based on privacy calculus of personal information disclosure in smartphone LBS applications.

Privacy-protective behavior can be classified into passive behavior and active behavior. Passive behavior includes refusal, misrepresentation, and removal, while word-of-mouth, complaint, and seeking for help belong to active behavior. Internet users in different countries may take different types of privacy-protective behavior because of cultural and social differences. This study analyzes the differences in Internet users' privacy-protective behavior between Korea and China. Korean Internet users take refusal, complaint, and seeking to protect their privacy information, while misrepresentation is not an option for Korean Internet users. Chinese Internet users take refusal, complaint, seeking, and misrepresentation to protect their privacy information. In Korea, passive behavior (refusal) is chosen more often than active behavior (complaint and seeking for help), while in China active behavior(complaint and seeking for help) is preferred to passive behavior (refusal and misrepresentation). The differences of privacy-protective behavior in the two countries may provide some implications for online companies, if they want to avoid the business risk due to privacy concerns and to take appropriate steps to deal with privacy-protective behavior by Internet users.

This research aims to analyze the factors affecting the acceptance of social commerce, including performance expectancy, effort expectancy, social support, facilitating conditions, hedonic motivation, habitability, price saving orientation, and privacy concerns using the Unified Theory of Acceptance and Use of Technology (UTAUT2). UTAUT2 has been examined and modified in various contexts. The research model studies the acceptance and use of technology in the context of customers. This study adopts a quantitative method using the partial least squares regression (PLS) approach involving 244 respondents. The respondents are users of social commerce in Indonesia. The result of this research indicates that social influence, facilitating conditions, hedonic motivation, habit, price value orientation, and privacy concerns have a significant effect on behavioral intention. On the other hand, performance expectancy and effort expectancy does not affect behavioral intention. Furthermore, price value has a significant effect on social commerce user behavior. Lastly, facilitating conditions and habits does not affect social commerce user behavior. This research contributes to the development of theory by examining an additional variable, which is privacy concern. This study is significant since social media and social commerce have grown exponentially nowadays. Implications of the results for the development of the theory (UTAUT2) and practice are discussed in the article.

Frequent outbreak of intrusion of private information is occurring recently not only at portal sites but also in electronic information service of public agencies. Due to these intrusions, it is observed that the citizens tend to avoid providing their private information even to the service for public agencies. Therefore, the object of this research can be explained as demonstrating the influence of the intention of provision for private information to foster the selectronic information ervice of the public agencies. In order to achieve this, this research intends to demonstrate how the experience of the intrusion of the private information affects the concern about the privacy and how the information factor from the public electronic information service has influence on the reliability toward the public. The results showed that the experience of intrusion of privacy, awareness of the danger of privacy, and the sense protection of the information from the manager at public agencies have direct influence on the concern of privacy. Meanwhile, it has been verified that the awareness of information protection of a manager, the systemicity of information protection, and the surveillance and punishment of information protection have influence on the reliability of public agencies.

The growing concern for the protection of personal information has made it critical to implement effective technologies for privacy and data management. By observing the limitations of existing approaches, we found that there is an urgent need for a flexible, privacy-aware system that is able to meet the privacy preservation needs at both the role levels and the personal levels. We proposed a conceptual system that considered these two requirements: a graph-based, access control model to safeguard patient privacy. We present a case study of the healthcare field in this paper. While our model was tested in the field of healthcare, it is generic and can be adapted to use in other fields. The proof-of-concept demos were also provided with the aim of valuating the efficacy of our system. In the end, based on the hospital scenarios, we present the experimental results to demonstrate the performance of our system, and we also compared those results to existing privacy-aware systems. As a result, we ensured a high quality of medical care service by preserving patient privacy.
