The amount of personal information collected by organizations and government agencies is continuously increasing. When a data collector publishes personal information for research and other purposes, individuals' sensitive information should not be revealed. On the other hand, published data is also required to provide accurate statistical information for analysis. k-Anonymity and ${\iota}$-diversity models are popular approaches for privacy preserving data publication. However, they are limited to static data release. After a dataset is updated with insertions and deletions, a data collector cannot safely release up-to-date information. Recently, the m-invariance model has been proposed to support re-publication of dynamic datasets. However, the m-invariant generalization can cause high information loss. In addition, if the adversary already obtained sensitive values of some individuals before accessing released information, the m-invariance leads to severe privacy disclosure. In this paper, we propose a novel technique for safely releasing dynamic datasets. The proposed technique offers a simple and effective method for handling inserted and deleted records without generalization. It also gives equivalent degree of privacy preservation to the m-invariance model.

This study explored the moderating effects of security ability on the influence of privacy concerns on internet activity using Korea media panel survey data. To this end, we applied between-subjects factorial design between 2 (privacy concern high / low) × 2 (security ability high / low) groups and compared five types of internet activity among four groups by variance analysis. As a result, privacy concerns have a main effect on internet activity, and security ability have a moderating role in this relationship. Despite the privacy concerns, people do their internet activities in order to enjoy the benefit from the internet. This study have academic implication in that it focus on the issue of privacy paradox in terms of the type of internet activity. In addition, practical implications are that, in order to activate online activities of individuals in an internet-connected society, efforts for enhancing their security abilities are necessary.

This study analyzes the copyright problems of document delivery services based on interlibrary loan which are operated by KERIS and KISTI according to the agreements with KORRA. As a result of the study, we found that there are limitations of the libraries and copyright works to implement the document delivery services. Also, the electronic document delivery is the only between librarians and there is no provisions in the agreements for individual users who are not affiliated to libraries. This study suggests introduction of the ground provision for the interlibrary loan in the Copyright Act of Korea and development of authoritative guideline for details of document delivery services. Also, the study suggests that end users to request documents could be print out it but the library have to install systems to avoid copyright infringement. Finally, the study proposes the copyright fee based model for the document delivery services for individual users.

Despite the early success story, the pan-industry diffusion of big data has been slow mostly due to lack of confidence of the value creation and privacy-related concerns. The problem leads us to the need to a stakeholder analysis on the adoption process of big data. The present study combines technology acceptance model, task-technology fit theory, and privacy calculus theory to integrate the positive and negative factors on the big data adoption. The empirical analysis was performed based on the survey from the current and potential big data users. Results revealed perceived usefulness, task-technology fit, and privacy concern are significant antecedents to the intention to use big data. Furthermore, there are significant differences in the perceptions of each constructs among groups divided by the types of big data use, with several exceptions. And the control effect was found in the magnitude of the relation between independent variables and dependent variable. The theoretical and politic implications of the analysis are discussed as to the promotion of big data industry.

In advanced mobile devices environment, the market share of mobile application has been increased. Among various mobile services, Location-based Service (LBS) is an important feature to increase user motivation related to purchase intention on mobile. However, individual privacy has also increased as an important problem for invasion of privacy and information leakage while too many LBS based applications (App) rapidly launched in the App market. In this study, we focused on perceived values of LBS App users who use Apps related to recommending best restaurants in China and South Korea. The purpose of this study is to identify important factors for perceived value when users provide personal information for LBS service provider. The result of this study is follows: perceived value can increase while LBS customers can more control self-information and information useability. Also information ability of users affected perceived values for LBS Apps. Also users' app user ability and perceived value were effects on privacy revenue. In addtion, perceived weakness of users and perceived value increased privacy threat.

Korean citizens enjoy not only the freedom of communication but also the secrecy of electronic communication. Article 18 of the Constitution of the Republic of Korea prescribes that the secrecy of correspondence should not be infringed. Namely, all citizens enjoy guaranteed privacy of correspondence. But many people have been experiencing the infringement of those rights. The purpose of this paper is to evaluate whether Paragraph 2, Article 13 of the Act on Protection of the Secrecy of Correspondence infringes on the constitutional rights of privacy of electronic communication. The results of this study indicate that the law violates the Constitution. Paragraph 3, Article 12 (Personal Liberty, Personal Integrity) of the constitution stipulates that "Warrants issued by a judge through due process (upon the request of a prosecutor) have to be presented in case of arrest, detention, seizure, or search." However, prosecutors, the police, and National Intelligence Service have made numerous inquiries calling for the journalists' telephone records without warrants issued by a judge. So, this study suggests that the paragraph should be amended to be compatible with the Constitution. Meanwhile, journalists should make a more concerted effort to protect their news sources in exercising constitutionally protected freedom of the press.

This paper summarizes the legal problems and issues raised in relation to generative AI. In addition, we looked at what regulatory discussions individual countries or international organizations have in order to solve or respond to these issues or to minimize the risks posed by generative AI. Infringement of individual basic rights raised by generative AI, the emergence and control of new crimes, monopolization of specific markets and environmental issues are mainly discussed, and although there are some differences in the necessity and direction of regulation, most countries seem to have similar views. Regarding AI, the issues that are currently being raised have been discussed continuously from the beginning of its appearance. Although certain issues have been discussed relatively much, there are some differences between countries, and situations that require consideration of phenomena different from the past are emerging. It seems that regulations and policies are being refined according to the situation of individual countries. In a situation where various issues are rapidly emerging and changing, measures to minimize the risk of AI and to enjoy the utility and benefits of AI through the use of safe AI should be sought. It will be necessary to continuously identify and analyze international trends and reorganize AI-related regulations and detailed policies suitable for Korea.

The release of iPhone by Apple in 2009 has changed the life pattern of an individual tremendously. That is, with the emergence of a smart phone, various services including voice/video call, camera, receiving and sending of e-mail, and web browsing have been realized. However, the broader the scope of the use of a smart phone has become, the greater the need for companies to introduce an MDM solution for protecting important documents has become. However the MDM solution may have a problem in that all data such as contacts, pictures, and memos saved in the smart phone can be accessed unlimitedly. For this reason, there is a risk that unwanted violation of privacy may happen to smart phone users. This paper proposed a plan to protect a personal privacy file of smart phone users, which disables access by others except for related smart phone users by enabling a person in charge of security or an MDM manager in a company to have access only to the file which was allowed by smart phone users to be disclosed and by saving non-disclosed files in a virtual disk.
