  • This paper shows the watermarking system that inserts copyright holder's logo in music file. In other words, a sound file is able to have an image information like a logo or letters. The watermarking system converts a sound file into an image file using spectrogram. In the spectrogram domain, a logo is inserted using spread spectrum. The proposed technique shows that the verification of copyright is better than the method using PN-Sequence.

  • The content industries environment has been undergoing significant changes due to rapid technological innovation and content market expansion. Interest in the industry is growing fast both in Asia and Europe. However, in Japan content industries are showing almost zero growth with no increase in overseas expansion. Until now, Japanese content industries have been able to grow based on domestic demands. Many different factors contributed to today's zero growth in Japanese content industries. Two main reasons are: 1) Their lack of interest in overseas expansion and 2) Insufficient investment in domestic human resources development. Considerable amounts of Japanese contents including films, music, games, and animations have been distributed in many Asian countries and today piracy problems in the region are at a serious level. According to 2004 records pirated editions accounted for 85%, 16%, 19%, and 36% in China, Korea, Hong Kong, and Taiwan respectively. Pirated editions bring economic losses to Japanese copyright profits. Making it worse, they weaken the motivation to create content and make it hard to activate cultural exchanges. Losses from copyright violations in Japanese content industries are expected to keep increasing in the future. In order to make Japan competitive and grow it is crucial to take proper measures to protect copyright infringements. This study considers the current situation of the Japanese content market, infringement issues in content which is causing many problems in Asian countries, including China, and facts about losses caused by this problem.

  • 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.

  • 본 논문에서는 믹스 음악을 위한 디지털 오디오 워터마킹 기술을 제안하였다. 믹스 음악은 기존에 저작권이 확보되어 있는 음악을 편집하여 한편의 오디오 클립에 다수의 음악이 포함되어 있는 재창조된 음악을 의미한다. 오디오 콘텐츠와 관련된 저작권료는 보통 완전체 오디오를 기준으로 부과된다. 그러나 믹스 음악의 경우에는 오디오 완전체를 모두 사용하는 것이 아니라 일부만을 이용하기 때문에 저작권료의 산정에서 저작권자와 사용자간의 분쟁의 소지를 갖고 있다. 본 연구에서는 이와 같은 오디오 저작권료와 관련된 문제의 기술적인 해결 방법으로서 믹스 음악을 구성하고 있는 각각의 오디오 콘텐츠에 대하여 서로 다른 워터마크를 삽입하여 음악을 구분할 수 있는 워터마킹 기술을 제안하였다. 제안된 기술은 기존의 워터마킹 방법과 달리 믹스음악을 구성하는 각각의 오디오에 대하여 서로 다른 워터마크를 삽입하기 때문에 오디오 전체에 대하여 워터마크를 삽입하는 기존의 방법과 달리 오디오의 품질을 떨어뜨리는 단점이 있다. 이에 대한 기술적 해결로서 비 가청성이 강조된 이진 랜덤 열을 이용하고 워터마크 삽입에 따른 신호의 왜곡 특성이 가장 적은 크기 변조 오디오 워터마킹 기술을 이용하였다. 제안된 방법은 워터마크의 추출 특성을 통하여 성능을 검증하였다.

  • 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.

  • Among human intellectual creations, the right granted by law to what is worth protecting is defined as intellectual property rights. Copyright is a legal right to creative finished products made by individuals, and in recent years, this legal right has been recognized as very important. In other words, copyright is a system created to protect the rights of individuals who created creations and to recognize their efforts. Works subject to copyright vary from poetry, thesis, novels to designs, paintings, music, and architecture, and the scope of the subject is gradually expanding. Recently, research has begun on how far the Metaverse design area absorbed into the real world among works. Computer-generated video productions and software program works are also subject to digital copyright protection, but it is also true that the interpretation of the author protection law for works, designs, and trademarks in the virtual world is unclear. This study aims to analyze copyrights based on case studies and theoretical backgrounds on copyright protection and to discuss the protection limitations of Metaverse design in the virtual world. In other words, the direction for the protection of Metaverse design is presented through clear distinction and definition of copyright protection in the tertiary virtual world. This study aims to present methods for design copyright protection in the era of Metaverse, respect copyright holders' creative activities, and develop our culture through protection of creations.

  • 이 글은 공연예술단체나 공연예술아카이브가 공연예술기록을 수집하는 과정에서 직면하게 되는 저작권 문제를 검토하기 위한 것이다. 이를 위해 공연예술 현장에서 수집할 수 있는 기록물의 종류를 구분하고, 기록물의 종류별로 저작권 문제를 법리적으로 분석하였다. 연구의 결과로 공연예술은 음악 무대 의상 등 다양한 영역이 어우러져 하나의 작품으로 재탄생하는 종합예술로서의 성격을 지니고 있어 그 자체로 상당히 복잡한 저작권 체계를 구성하고, 그 기록물은 공연 자체의 저작권과는 구별되는 또 다른 저작권을 발생시킬 수 있으며, 저작권은 기록의 종류와 실질적인 생산주체에 따라 다양한 양상으로 구성될 수 있음을 밝혔다.

  • In the digital world, the transactions of assets with intrinsic value can be applied to games, literature, art, and music by issuing NFTs (Non-Fungible Tokens) based on Blockchain; various NFT exchanges are emerging accordingly just like real world asset exchanges. However, there could be an issue of copyright infringement in those NFT transactions. Therefore, this paper has classified the types of copyright infringement that may occur in NFT exchanges and proposes the copyright infringement countermeasures according to them. For this purpose, 10 types of NFT exchange are examined. Eventually, it can be expected that the proposed countermeasures will contribute to the revitalization of the NFT market by providing solutions for those issues.

  • In this study, we investigated the necessity and limitations of music composition required in TV documentary by conducting in-depth interviews with 20 music directors currently working at Korean Broadcasting System (KBS). Our research has shown that composition of music is necessary. However, in reality, it is difficult to use the composed music due to problems such as time and cost of composing and trust in the music composer; so music libraries, film music, or other music are used instead of the composed music in many situations. However, at the time when companies like its rival Netflix are aware of the importance of sound, the impact of Netflix could lead to a decline in the quality of terrestrial TV, which could lead to a weakening of competitiveness. Recently, in the case of sound programs, the sales of secondary works are active due to "internet uploading using YouTube" or "exporting programs", but the sales have been hindered by restrictions on the use of copyrighted works. The music source of library is said to be the one whose copyright problem has been resolved. In this study, we show that the composed music is an ultimate alternative to TV documentaries, since the library music is sometimes suspended due to the situations of management companies.
