As logistic environment of digital resources is rapidly changing, protection of the intellectual property for digital resources has been recognized as one of important issues. Digital Rights Management (DRM) has taken much interests from ISP, authors and publishers of digital content as an integrated approach to create a reliable environment for access and the use of digital resource. In this paper we proposed a dynamic digital rights management system based on adaptive agent theory (ARPA : Adaptive Resource Protection Agent) to address problems facing contemporary DRM approaches : static rights management problem solving and strengthened monitoring/tracking system. We introduced a dynamic mission control scheme to realize dynamic digital rights management. We incorporated adaptive agent theory to implement on-and off-line tracking and protection. Through the implementation of protype system, the process, the process dynamic digital rights protection will be demonstrated.

To study product properties of digital spaces, we strongly need to formulate meaningful adjacency relations on digital products. Thus the paper [7] firstly developed a normal adjacency relation on a digital product which can play an important role in studying the multiplicative property of a digital fundamental group, and product properties of digital coverings and digitally continuous maps. The present paper mainly surveys the normal adjacency relation on a digital product, improves the assertion of Boxer and Karaca in the paper [4] and restates Theorem 6.4 of the paper [19].

Owing to the development of the notion of normal adjacency of a digital product [9], product properties of digital topological properties were studied efficiently. To equivalently represent a normal adjacency of a digital product, the present paper proposes an S-compatible adjacency of a digital product. This approach can be helpful to understand a normal adjacency of a digital product. Finally, using an S-compatible adjacency of a digital product, we can study product properties of digital topological properties, which improves the presentations of the normal adjacency of a digital product in [9] and [5, 6].

On the base of IT growth, competition between countries for preoccupation of digital content market is keen. And it is prospected that the development of digital content industry will be more rapid with the base of telecommunication infra-structure(for example internet, digital broadcasting) which is the main channel for distribution of digital content. The bill of "Act for Development of Online Digital Content Industry", has passed the national assembly jan, 2002, and "Draft Blueprint for Developing Online Digital Content Industry(2003$\sim$2005)" was made on the base on that law feb, 2003. And we can find measures for protect the digital content manufacture in the laws such as "Literary Property Law", "Trademarks Law" and "law for prevention of unfair competition". On this study we suggested three measures to make digital content industry more profitable by the method of research of related law and industry survey.

In recently, digital comic content distribution was not stable for illegal distribution and the weak of intellectual property right in the internet. The research activities of suggest the distribution model and secure intellectual property right are going in international standard communities, not yet in Korea. As the basis of the research, the general framework of international projects and standards such as MPEG-21, IMPREMATUR, FILIGRANE was analysed. Targeting on the domain of digital comics industry, the digital comics distribution structure and business flow model are defined adapting secured distribution system, DRM. The detail content of this research consist of three themes. The first, survey and analysis of the international standard ＆ leading DRM project's models. The second, suggestion of the service scenario on the digital comic content distribution. The third, suggestion of the model on the secured distribution of digital comics. Through this research targeting at the digital comics business, we found that standards technical items and requirements was well adapted into target domain, and would affect other domain in digital content industry.

From the viewpoint of Information Ethics. I tried to examine the moral justification of Intellectual Property Rights in the age of the digital information society. Lockian traditional argument of property rights which is based on the value of labor and Hegelian theory of personalization, both are not enough to justify the new Intellectual Property Rights. The notions of Intellectual Property Rights are to be changed. One change is from the absolute dominion over material property to the limited dominion over intellectual property. The change from property rights to process control rights is the other. To protect these intellectual property rights, there are three possible protection devices that we might take - legal protection, technical protection and moral protection. I argued that both legal and technical protection have some limitations, so the final way to protect the IP rights is to attempt to establish the moral protection as a fundamental solution.

The digital watermark is one of important techniques to solve copyright authentication problems of digital media. Researches on the digital watermark are rapidly increasing in various media. The watermark system can resist some attacks such as signal attack, geometric attack and protocol attach. However, so far the robustness of the watermark needs to be improved. This paper suggests a watermarking technique with which a watermark is embedded on a coefficient of wavelet-based frequency band and extracted from it for protection of property rights and authentication of Blackfin processor-based digital sound. By carrying out hardware implementation of the suggested sound watermarking, the commercialization of protection of property rights and robustness of watermarks resulted from development of high-level programs can be confirmed.

Digital content industry is growing rapidly because of the property of high-speed networking and greater demand for digital fulltext-image. However, we know the fact that it is many difficulty in production and supply for good quality of content. Hereupon, we suggest digital fulltext-image service framework to protect copyright. More concretely, we propose integrated model and reference model to securely serve digital fulltext-image by recompositing core objects and reconstructing the value-chain structure of digital content industry to framework including the process(from its production (creators or copyrighters) to consumption (users or consumers)). Also, we construct the digital fulltext- image service system based on reference model and reconstruct its interface that occurs between core subjects.

In this paper, we propose the digital video frame obfuscation method for intellectual property protection using the DC component of the intra frame and the motion vector of the inter frame at digital video encoding. The proposed method considers characteristics of the HVS (human visual system) which is sensitive at the low frequency and the middle frequency. This method makes the signal distorted as operating XOR between authentication signal and the DC coefficient of the intra frame including main information and the sign of the motion vector including edge motion, so that the video is normally displayed only when suitable authentication signal is applied.

In the Fourth Industrial Revolution era, creative ideas are creating enormous value. This study conducted a case study on curriculum management plans aimed at protecting ideas and their results, recognizing the importance of intellectual property (IP), and cultivating basic knowledge about intellectual property. In particular, this study looked at ways to quickly learn related issues regarding new intellectual property rights related to computer software and artificial intelligence. In addition, research was conducted on ways to learn about efficient protection and utilization of inventions through actual examples. This study checked the importance and necessity of the interaction and communication between instructors and learners through the status of distance learning in domestic universities and a case study of distance learning of convergence subjects. We aim to continuously research effective class management methods and contribute to academic development through case studies of convergence subjects.
