This paper reviews the applicabilities and the problems of copyright law and patent law to the computer-related intellectual properties such as data bases and computer softwares, with special reference to the practices in the advanced countries like U.S., U.K., and Japan. It also discusses Japanese proposals of-the new computer program right law which has been based on entirely different concepts of new media. The author concludes that the legal protection devices of any individual countries should be considered in the context of the eventual international agreements.

In this paper, we propose a watermarking method for still images using Discrete Cosine Transform (DCT). Watermarking is a copyright protection technique for digital contents by hiding secret information into the contents. The proposed method embeds the watermark information into DCT coefficients. To obtain a watermarked image that is not only high quality but also has robustness for compression, we considered a method to change the degree of embedding by utilizing the activity of each DCT block. The simulation results show that the proposed scheme can obtain huh quality watermarked images and we can extract most of the embedded data even if they are compressed by JPEG scheme.

본 연구는 3차원 컴퓨터 그래픽 데이터의 디지털 저작권 보호를 위하여 3차원 데이터에 저작권을 주장하는 워터마크를 삽입하고 원본 없이도 추출할 수 있는 방법을 제안한다. 본 연구에서는 벡터의 개념을 사용하는 3차원 모델 가운데서도 많이 사용되고 있는 Spline방식으로 모델링 된 그래픽 데이터에 정보를 삽입, 추출하는 기술로서 추출 시에는 원본을 필요로 하지 않는다는 것이 특징이다. 좌표자체를 변경하지 않기 때문에 정보를 삽입한 후 3차원 데이터의 양에 작은 변화가 있지만 시각적으로 구분이 안될 정도로 3차원 모델의 형태를 완벽히 유지한다. 또한 삽입된 정보가 쉽게 노출되지 않으며 많은 양의 데이터를 삽입할 수 있다.

The digital signal has been replaced the analog signal in most of every field of multimedia including still image, animation, and audio due to the enormous extension of computer supply and the fast development of computer network. The consumers of information are able to enjoy the abundance of information because of one of the digital signal traits that very easy to regenerate the original data. Because of the trait, however, it is very hard for the producers of information to keep the copyright with the merit of original copy in quality excellency. In this paper, the watermarking technology which inserts a RGB color watermark in color image using the visual characteristics of wavelet coefficient was proposed. As a result, the PSNR value of image was varied depending on perceptual parameter, but we can obtain 32dB as a whole.

As information and communication technology develops, it brings various benefits to our lives. However, information and communication technology has had various side effects in our lives. Representative side effects include internet addiction, smartphone addiction, copyright violation, personal information infringement, cyber bullying and hacking. Recently, smart phone addiction rate is increasing with the spread of smart devices in Korea. In this study, we analyze the correlation between age group and smartphone addiction. In order to obtain fair and objective results, statistical analysis was performed based on the national statistical data of the National Information Society Agency. The results showed that the infant group and the adult group were correlated with the smartphone addiction rate. In this study, we analyzed the causes of smartphone addiction for different age groups. We also discuss dangers of smartphone addiction for different age groups. In additions, we proposed various ways to prevent and cure smartphone addiction for infants, adults, and senior citizen group. The results of this study are expected to be widely used as a remedy for smartphone addiction and future smartphone addiction research works.

The Code of Ethics for Newspaper Advertising in Korea, first implemented in 1976 and subsequently revised in 1976, 1996, and 2021, is a critical regulatory instrument for the country's advertising sector. However, the specialized domain of "advertising ethics," particularly the "code of advertising ethics," remains under-explored. This research addresses this scholarly gap, providing an empirical analysis of the 2021 amendment's revision trajectory. This study employs a robust methodological approach, integrating expert interviews and small-group AHP-based surveys. This approach allows for a comprehensive understanding of the revision needs, referencing existing ethical codes studies, and comparing similar ethics codes nationally and internationally. The research further investigates key challenges such as personal data protection and copyright issues in the rapidly evolving digital media landscape, while preserving the existing code's inherent value. The findings are expected to significantly contribute to the emerging field of advertising ethics in Korea, offering practical implications for future code revisions.

As Open Data has been emphasized globally, discussions on data policies have occurred for minimizing problems resulting from data sharing and reuse. This study aimed at investigating policy components for controlling access and use of data and examining similarities and differences of the policy components across disciplines. For the purpose, the study analyzed policy components for data access and use controls provided by 37 research data repositories overseas. These included twenty repositories in biological and health science, ten in chemistry, earth and environmental science and physics, as well as seven in social science and general science. The analysis showed that common policy components involve copyright/licenses, data citation, disclaimers and embargoes. However, there were differences in diversity of policy components among the disciplines and it indicated that the rationales of access and use controls emphasized would be different in the disciplines.

Matters related to the right to be forgotten started the dispute Europe to introduce it first when Data Protection Directive established in 1995 proceeded revision. Relating to this, diverse disputes proceed on responding to personal information protection and internet laws in our nation. Especially as our National Assembly submitted the law regarding the promotion of information and communication network use and protection of information and amendment of copyright, it is necessary to look into the movement on introduction of law of right to be forgotten closely in detail. EU which attempted the institutionalization for the first time, relating to review of General Data Protection Regulation, proposed opinions such as the necessity to define subjects of personal information concretely and specifically and or protection target and balanced consideration on freedom of expression which is constitutional value. In the case of our nation, there was legislation attempt to introduce the regulation but it was limited in the form of fallen effectiveness without concrete and detailed review on internet law. To solve such problems, it is necessary to look into issues and matters to be considered required to accept right to be forgotten closely and discuss possibility of introducing right to be forgotten, conflicts between fundamental rights becoming issue, effect of goal achievement of personal information protection through the system introduction, and other rational acceptance method.

In this paper, we propose a new watermarking method based on spread spectrum and a semi-fingerprinting system architecture that can be built using our robust watermarking method. Especially, we describe a method that extends the application area of watermarking technology to more practical application domains by applying the watermarking technology that has been focused mainly on copyright protection to fingerprinting area. Our proposed watermarking scheme uses the method that inserts more data by using random number shifting method. We improved the reliability of acquired data with 20-bits CRC code and 60-bits inserted information. In addition, we designed the system architecture based on the recommendation of cIDf (content ID forum) in order to apply the system on the semi-fingerprinting area.

Only requiring research reports or publishing articles as the final obligation of R&D activities is not sufficient to utilize and reproduce the knowledge information. Since a lot of important data have been ignored and missed by the public or private research institutions, it is not easy to manage and utilize R&D outcomes and to develope knowledge-intensive business as we expect. It is important and rather urgent matter that we should reexamine the related regulations/ laws of Intellectual Property and observe the practical problems of data utilization in real settings. This study reviewed recent studies about domestic R&D institutions, current regulations related IP, and some conflicts with the copyright, and then summarized the problems/ solutions of utilizing R&D information as knowledge assets.
