Recently, the invasion of privacy in medical information has been issued following the interest in the secondary use of mass medical information. The mass medical information is very useful information that can be used in various fields such as disease research and prevention. However, due to privacy laws such as the Privacy Act and Medical Law, this information, including patients' or health professionals' personal information, is difficult to utilize as a secondary use of mass information. To do these problem, various methods such as k-anonymity, l-diversity and differential-privacy that can be utilized while protecting privacy have been developed and utilized in this field. In this paper, we discuss the differential privacy processing of the various methods that have been studied so far, and discuss the problems of differential privacy using Laplace noise and the previously proposed differential privacy. Finally, we propose a new scheme to solve the existing problem by adding a 1-bit status field to the last column of a given data set to confirm the response to queries from analysts.

In recent years, the privacy concern for mobile consumers is emerging as the use of mobile application(apps) is growing according to the rapid spread of mobile devices such as smart phones and tablet PCs. To improve privacy protections in the mobile communications and apps, overseas organizations are announcing guidelines and/or checklists for stake holders. Although personal information protection guidelines for application developers have been prepared in the country, efforts to improve consumer privacy capability is insufficient. Thus, in this paper we first scope the app privacy related guidelines in both domestic and foreign affairs, then present the risk factors of privacy invasion by the stage of mobile application use based on the "Privacy Protection Act", offering privacy checklists for consumers. This checklist will enhance the self-management capability of consumer privacy and create virtuous cycle in the mobile ecosystem.

Library users must provide their personal information to libraries. This study surveyed these library users' perception of privacy and the effect of the education after providing library user privacy education. As a result, first, it was found that after education, users were more interested in their privacy, rated the problem of library user privacy as more severe, and rated library user data collection as more likely to be considered privacy invasion. Second, we investigated users' perception of how much user service records being collected in libraries violate users' privacy, which showed a great perception change in 25 questions after the education. Third, in the survey about library and librarians' efforts for protecting library user privacy, it was found that all 15 questions were rated as significantly more important after education.

Recently invasion of privacy problem in medical information have been issued following the interest in secondary use of large medical information. These large medical information is very useful information that can be used in various fields such as disease research and prevention. However, due to the privacy laws such as Privacy Act and Medical Law, these informations including patients or health professionals' personal information are difficult to utilize secondary. Accordingly, various methods such as k-anonymity, l-diversity and differential-privacy that can be utilized while protecting privacy have been developed and utilized in this field. In this paper, we study differential privacy processing procedure, one of various methods, and find out about the differential privacy problem using Laplace noise. Finally, we propose a new method using the Shamir's secret sharing method and symemetric key encryption algorithm such as AES for this problem.

Along with the development of digital technologies, the information obtained during the medical procedures was working as a source of valuable assets. Especially, the secondary use of personal health information gives the ordeal to privacy protection problems. In korea, the usage of personal medical information is basically regulated by the several laws in view of general and administrative Act like Medicine Act, Public institutions' personal information protection Act, Information-Network Act etc. There is no specific health information protection Act. Health information exchange program for the blood donor referral related with teratogenic drugs and contagious disease and medical treatment reporting system for income tax convenience are the two examples of recently occurred secondary use of health information in Korea. Basically the secondary use of protected health information is depend on the risk-benefit analysis. But to accomplish the minimal invasion to privacy, we need to consider collection limitation principle first. If the expected results were attained with alternative method which is less privacy invasive, we could consider the present method is unconstitutional due to the violation of proportionality rule.

This paper deals with the online privacy policy, which is designed to solve the information asymmetry problem between websites and internet users. We empirically analyze the recognition, confirmation of the online privacy policy, and its effects on online transaction behavior using a rich survey data representing 5,422 Korean internet users. Major results are as follows. First, there exists a significant difference between recognition and confirmation, and confirmation behavior is positively related with the importance of privacy issue and the experience of privacy invasion. Second, binary variable regressions show that internet user tends to participate in online transaction if he/she confirms the online privacy policy positively. Finally, if websites would make online privacy policy easy and short, a yearly online transaction market size of Korea would increase by 0.46 million participants and 22.4 billion KRW.

The purpose of this paper is to examine the ethical implications in UCC participation. This paper aimed at examining the advent of UCC as a critical media tool in interactive two-way communication and the effect of ethical questions on the level of UCC participation. The findings show that uncertainty avoidance gives an positive and significant effect on privacy concern and regulatory preference, but it is not related to copyright invasion in Korea and U.S.A. It is shown that privacy concern does not influence on UCC retrieval in Korea whereas it is positively related to UCC retrieval in the United States. Also, privacy concern has not relationship with UCC production(modification, recreation, generation) in both nations. In the case of regulatory preference, it posits an significant and positive effect on UCC retrieval in Korea while it is not related to UCC retrieval in the United States. Also, regulatory preference does not affect on UCC production in Korea whereas it influences on UCC generation without impacting UCC modification and recreation in U.S.A. Finally, the results show that copyright invasion has stronger relationship with UCC recreation and generation than UCC modification, and it is positively related to UCC retrieval in both nations.

As the privacy issues are all around the world, the intrusion into personal privacy is concerning. For that reason, government established the article from the personal information protection law that has to notice the privacy policy to users on the online site. and the matter of privacy invasion make concern toward behavior of online user. Although there are rules to carrying legal binding force in accordance with, because it is full of text and uncomfortable to read so that its readability is low. In the same context, each other has different state of understanding with the policy for personal information has been playing an important role. In this approach, companies and government do not think this over deeply and do just for what their practical use is. That is the reason why this research start, and the result expecting for real. As the result in the participant who cognize the privacy policy display pattern, they have certain type to do. In this article, the certain behavior doing is remarkable with the privacy policy. According to privacy concern, privacy fundamentalist reveals such a compromise reaction to protect their information when they know what information which the privacy manager of service provider collect. This study arrives at the result depending on the gap of privacy group that the group of checking the policy contents, especially the group which has high privacy concern, they move forward to protect their emotion and put a constructive plan into protective action.
