There have been proposed various copyright protection protocols in network-based digital multimedia distribution framework. However, most of conventional copyright protection protocols are focused on the stability of copyright information embedding/extracting and the access control to data suitable for user's authority but overlooked the privacy of copyright owner and user in authentication process of copyright and access information. In this paper, we propose a solution that builds a privacy-preserving proof of copyright ownership of digital contents in conjunction with keyword search scheme. The appeal of our proposal is three-fold: (1) content providers maintain stable copyright ownership in the distribution of digital contents; (2) the proof process of digital contents ownership is very secure in the view of preserving privacy; (3) the proposed protocol is the copyright protection protocol added by indexing process but is balanced privacy and efficiency concerns for its practical use.

The paper analyzes a copyright owning firm's incentive to enforce its copyright in the presence of file-sharing networks. I devise a two-period model where a copyright owner sells two different versions of a creator's information good, and show that the firm's overall profits are enhanced by a strategy of differential inter-temporal enforcement of the copyright protection, compared to strategies of no enforcement or full enforcement in both periods. If the firm enforces no copyright protection in the first period, the low-valuation consumers may make and consume copies that are imperfect substitutes for the original information good. If there is a significant increase in the willingness-to-pay of some low-valuation consumers after they experience the information good, the firm can extract the increased consumer surplus by enforcing a positive level of copyright protection in the second period. Social welfare, however, is maximized in the case of no enforcement.

In this paper, we investigated the information gifted teachers' recognition about the copyright and developed a copyright education. Firstly, we compared the copyright-related knowledge, affective, and attitude with the information gifted teachers and regular classroom teachers. As a result of survey, we found that a copyright education in the teacher training for the information gifted was needed, because it was not different between two groups. Accordingly, we developed the copyright education program in the teacher training for the information gifted. We also verified an effectiveness of proposed copyright education program by expert group testing. We expect that this study will contribute the spread of copyright cognition in the information gifted education.

Copyright is challenged by the rapid development of digital technology. This study investigated a number of new copyright-related issues : electrocopying, digital transmission, legal definition of multimedia, moral right, fair use et al. To use copyright works we need licensing of rights and permissions. Then at this paper we examined the scopes and contents of permission with copyright owners or publishers, also considered relationships of copyright owners with distributors and end-users. Finally, to protect rights of copyright owners and use freely copyright works, we suggested introduction of 'collective management system of copyright' and construction of 'copyright management information system' .

The copyright law is the greatest legal tool for promoting access to knowledge and information by striking a balance between owners rights and users rights. For libraries, copyright limitations and exceptions are critical to meeting our missions to support learning and research, promote the flow of information, provide equitable access to information to the public, preserve intellectual and cultural heritage. Based on these reasons, this study analysed the limitation of copyright law of Korea for library, suggested improvement of reproduction for the library preservation and distribution including rental and lending, printout and transmission of internet information resources, copy of library materials which are rarely available through normal trade channel and government publications, reproduction and electronic transmission for persons with disabilities, and proposed fair use model(limitations on exclusive rights) for libraries.

With the advances in Information Technology (IT), users can download or stream copyrighted works, such as videos, music, and webtoons, at their convenience. Thus, the frequency of use of copyrighted works has increased. Consequently, the number of unauthorized copies and sharing of copyrighted works has also increased. Monitoring is being conducted on sites suspected of conducting copyright infringement activities to reduce copyright holders' damage due to unauthorized sharing of copyrighted works. However, suspected copyright infringement sites respond by changing their domains or blocking access requests. Although research has been conducted for improving the effectiveness of suspected copyright infringement site detection by defining suspected copyright infringement sites' response techniques as a lifecycle step, there is a paucity of studies on automation techniques for lifecycle detection. This has reduced the accuracy of lifecycle step detection on suspected copyright infringement sites, which change domains and lifecycle steps in a short period of time. Thus, in this paper, an automated detection technique for suspected copyright infringement sites is proposed for efficient detection and response to suspected copyright infringement sites. Using our proposed technique, the response to each lifecycle step can be effectively conducted by automatically detecting the lifecycle step.

The National Archives of Korea(NAK) has arranged and operated 'Guidelines on Operating Copyright for Archives' and 'Regulations on Operating Reference Room' to protect the copyright for archives. However, the Guidelines and the Regulations only provide application to the Copyright Act and principles on internal managing copyright without presenting copyright issues for each type of archives. Therefore, additional detailed guidelines have to be arranged for the users to access to copyright issues easily by presenting them the standards of judgement or principles on copyright issues for each type of the archives to facilitate the use of archives collected already. We also need to define the details on Copyright Act and Moral Rights Act to collect archives. This study is an prior analysis for that purpose. Lively discussion and way of operation in an aspect of the copyright in relation to private records should be sought in the future.

Digital works such as computer programs, music, photographs, movies and dramas are copyrighted. Even if there were more than 1,000 violations per year for digital works, the punishment was very weak. Especially copyright infringement by teenager is increasing. This study aims to present the direction of future development through questionnaires on the perception and direction of college students about copyright. 157 college students were surveyed about copyright awareness, perception of detailed legal provisions, cost of monthly expenses, copyright violation, and direction of copyright protection. As a result of the questionnaire survey, awareness was high at 69%, but in detailed law was low at 17.2% and 22.3%. In the future direction of copyright policy, 72.6% of them answered that they should be "strengthened" and "more and more strengthened". In order to protect copyrights, enforcement of crackdowns, public relations activities, expansion of the legal market, and technical protection should be done. In order to do this, copyright-related education for elementary, middle, high school and college students are needed more and it is necessary to expand the legal market where high quality contents are traded. More research is needed on copyright protection technological methods.
