Recently, Syntheic data has been in the spotlight as a technology that can protect personal information while maintaining the patterns and characteristics of actual data. Accordingly, technical and institutional research on synthetic data is actively being conducted, but it is difficult to actively use synthetic data due to the lack of clear standards and guidelines. This study is a preliminary study for quantifying the disclosure risk of synthetic data, and derives a privacy disclosure risk index through statistical methodology and suggests specific application measures to comply with the General Data Protection Regulation(GDPR). It is expected that the disclosure risk and the balance of data utility can be controlled through the privacy disclosure risk index of this study in an open data environment.

The purpose of this study was to investigate the shopping values(utilitarian and hedonic values) sought and the risks(economic, functional, socio-psychological, and privacy) perceived by consumers who participate in Internet auctions by determining the factors that affect their shopping values and risk perceptions. Empirical data were collected by an Internet survey of netizens who were interested in and had experience in Internet auctions. Questionnaires were distributed to the subjects through an Internet survey site and at an Internet auction cafe. A total of 300 questionnaires were analyzed. The results showed that consumers showed a slightly greater pursuit of a utilitarian value than a hedonic outcome in their Internet auction practices; however the outcomes pursued by consumers in their teens and twenties tended to be more hedonic than utilitarian. Consumers with a higher level of innovation, self-confidence in purchase, and need for information searching showed a greater pursuit of utilitarian and hedonic outcomes. The group of consumers with a higher expectation for legal protection pursued a more utilitarian outcome, whereas the group of consumers with higher influence from the reference group pursued a more hedonic outcome. The consumers showed that they perceived functional risk as boing most serious, followed by privacy risk, economic risk, and socio-psychological risk. Subjects with higher degrees of innovation, self-confidence in purchase and self-control perceived economic risk as critical. Functional risk was perceived to be highest in the group of consumers with self-control and a need for information searching, whereas socio-psychological risk was perceived to be highest in the group of consumers showing more self-control. Privacy risk was perceived to be highest in the group of consumers with a higher degree of innovation and lowest in both groups of higher and lower affection. Both economic and privacy risks were perceived to be lower in the group of lower pursuit of a hedonic outcome.

This study built the theoretical frameworks for empirical analysis based on the analysis of the relationship among the concepts of risk of information privacy, the policy of information privacy via the provision studies. Also, in order to analyze the relationship among the factors such as the concern of information privacy, trust, intention to offer the personal information, this study investigated the concepts of information privacy and studies related with the privacy, and established a research model about the information privacy. Followings are the results of this study: First, the information privacy risk has the positive effects upon the information privacy concern and it has the negative effects upon the trust. Second, the information privacy policy has the positive effects upon the information privacy concern and it has the negative effects upon the trust. Third, the information privacy concern has the negative effects upon the trust. At last, the information privacy concern has the negative effects upon the provision intention of personal information and the trust has positive effects upon the offering intention of personal information.

In Internet of Things (IoT) era, more diverse types of information are collected and the environment of information usage, distribution, and processing is changing. Recently, there have been a growing number of cases involving breach and infringement of personal information in IoT services, for examples, including data breach incidents of Web cam service or drone and hacking cases of smart connected car or individual monitoring service. With the evolution of IoT, concerns on personal information protection has become a crucial issue and thus the risk analysis and management method of personal information should be systematically prepared. This study shows risk factors in IoT regarding possible breach of personal information and infringement of privacy. We propose "a risk analysis framework of protecting personal information in IoT environments" consisting of asset (personal information-type and sensitivity) subject to risk, threats of infringement (device, network, and server points), and social impact caused from the privacy incident. To verify this proposed framework, we conducted risk analysis of IoT services (smart communication device, connected car, smart healthcare, smart home, and smart infra) using this framework. Based on the analysis results, we identified the level of risk to personal information in IoT services and suggested measures to protect personal information and appropriately use it.

The purpose of this research is to identify effect of communication strategy as effectively communication method which is decreasing Internet Web site users' perceived information privacy concerns as important factor affecting to positive behavior or behavioral intentions on long-term relational outcome perspectives. This study suggests alternatives concepts and causal relationship about information privacy issues. First, it addressed collaborative communication strategy (CCS) model of effective communication method for Web site's IPP to users. Second, it provided comparing and integrating streams of information privacy research on long-term relational outcomes perspective. Third, it assessed effectiveness of Web site's IPP on organization legitimacy ensured continuous survival of organization. A research model was proposed and subsequent hypotheses were empirically tested with partial least square (PLS) based on 684 responses from the users of 21 Internet Website among entirely finance, recruit, portal /e-store Web site. It was learned that CCS(as a communication method) and relationship quality(representing long-term relational outcomes)was positively associated with decreasing user's IPC more than privacy risk. Also, legitimacy to information privacy practice positively associated with willingness to information providing more than negative effect of IPC. Lastly, their association strength was partially moderated by the type of real information sensitivity.
