The purpose of this study is to explore the antecedent factors to the piracy of the digital copyrights in order to provide basic data for piracy prevention policy. The findings of study revealed that most respondents had experiences to copy MP3 files illegally. And many respondents answered they didn't copy pirated material by themselves but others did piracy a lot. The feeling of quilt and anxiety against piracy is shown very low level. Low copy cost and regulation level significantly impact upon the cognitive level of other's piracy. Updated contents, the higher price of authenticated materal, piracy regulation are the significant antecedent factors to the level of piracy. The level of piracy activity and anxiety against piracy are significantly different by age. The cognitive level of other's piracy, piracy activity and anxiety are significantly different by gender.

In this paper, we proposed a mechanism that prevents indiscreet use of digital contents, verifies created content's copyrights to provide services to granted user and protects digital contents by law by authenticating the original digital content whenever an infringement of copyright occurs in UCC environments. The proposed mechanism uses specific information and features of contents as copyrights authentication information without additional information. Also, provides the fact of violation by inferring the modification of the original digital contents. That means this mechanism infers same or similar value from the contents; fraudulent use of content, modification of content color, modification of content format, modification of content resolution and illegal use of frame not principal key frame. In that point, we found that the inferred value from the content differed according to features of content modification.

In the past, the judicial circles in the Republic of Korea (ROK) were generous to the online copyright violations of computer software compared to other academic areas or offline violation. However, they started to reconsider such a practice since the FTA talks with some advanced countries began so that new laws had to be established, especially after the first round of negotiations with United States of America (USA) in 2006 during which they changed their views on the matter. Now it became possible to penalize digital copyright violations through lawsuits, and from March 1st, 2017, the court is expected to abolish the nonsuit system for teenagers. Thus, this paper has reviewed the ethical aspects involved in digital copyright protection and examined the possible alternatives, dividing them into three broad groups, before proposing a digital copyright protection curriculum for secondary education.

In network service environment, cultures from diversified fields are easily accessible thanks to the convenient digital content services. Unfortunately, unauthorized access and indiscreet misuse behaviors have deprived content owners of their copyrights. This study suggests an integrity-ensured model applicable for forensic evidence of digital content infringement in network service environment. The suggested model is based on MPEG-21 core components for digital content protection and the system is designed in connection with the components of digital content forensics. Also, the present study suggests an efficient technology to protect and manage computer forensic evidence and digital content by authorizing digital content use and catching infringing logs of authorized users without lag in network environment for the benefit of network security and reliability.

문자메시지는 이동통신망에서 무선 데이터 서비스를 위해 가장 널리 사용되는 서비스이다. CDMA 이동통신망에서는 문자메시지 서비스는 한번에 50자의 한글을 전송 할 수 있다. 문자메시지 서비스가 일반화되고 MIDI, MP3 등의 멀티미디어 기능을 갖는 칼라 휴대폰이 보급됨에 따라 이동통신사업자는 멀티미디어 메시지를 문자메시지와 같이 P2P로 전송할 수 있는 NMS(Multimedia Massage Service)를 표준화하고 서비스하고 있다. MMS는 문자메시지와 같이 이동통신사업자의 비음성 서비스의 주요 매출 원으로 역할을 할 것으로 기대되고 있다. MMS가 활성화되면 MMS에 첨부되는 멀티미디어 콘텐츠의 저작권을 보호하기 위한 방안이 마련되어야 할 것이다. 본 논문에서는 MMS 시스템의 변경을 최소화하면서 콘텐츠 저작권 보호를 위한 DRM이 적용된 MMS DRM 시스템을 제안한다. 제안된 MMS DRM 시스템은 DRM Packager, DRM Server, DRM Agent를 통하여 MMS에 첨부된 멀티미디어 콘텐츠를 보호하고 다양한 사업모델을 지원할 수 있도록 하여 MMS 활성화에 기여할 것이다.

오늘날 DRM(Digital Right Management)은 악의적인 사용자에 의한 디지털 콘텐츠의 재배포, 불법 복제를 금지시키기 위해서 사용되고 있다. 그러나 여전히 현재 DRM 시스템은 상호 호환성 부족으로 인해 사용자의 불편을 초래하고 있다. 이를 해결하기 위해 상이한 DRM 시스템의 상호 호환을 위한 연동 방안이 제시되고 있다. 본 논문에서는 상이한 DRM 시스템 호환을 위해서 공통평가기준에 따른 보호프로파일을 개발한다. 특히 이러한 개발을 위해 기존에 개발된 보호프로파일을 이용해서 개발에 적용시킴으로써 시간 효율과 비용 측면에서의 효율적임을 분석을 통하여 보인다. 개발된 보호프로파일은 콘텐츠 제공자 및 사용자 권한을 관리하는 관리자가 안전한 저작권을 유지할 수 있는 요구사항을 도출할 때 참고 자료로 활용 될 수 있다.

This study aims to expose the potential dangers of K-pop through the past and present of K-pop choreography copyrights and to suggest the need to secure digital choreography copyrights for the sustainability of K-pop considering national responsibility. As the content industry quickly sought countermeasures to digital transformation, such as the launch of K-pop platforms and the evolution of OMO (Online Merges with Offline) media commerce in response to changes in the industrial environment due to COVID-19, the annual export of the domestic content industry increased by 6.3% compared to the previous year. Accordingly, our copyright does not require that works be fixed in tangibles, as in Japan and Germany, on the basis of entrusting each country's legislation to determine whether to require fixation on choreographed works. On the other hand, the United States, France and the United Kingdom are demanding that it be fixed. Although choreography is at the center of K-pop and the value and influence of K-pop videos including cover dance through new media are discussed from various perspectives, copyright on choreography that needs to be resolved in business platforms for K-pop scalability The fact that there is such a big difference in problem perception is an area where we must not lose our vigilance. As the development of today's technology, the method of fixing a choreography looks very easy as an image, but at the same time can be stolen very quickly. Therefore, compared to overseas cases, it is urgent to improve the difference in perception of copyright registration for K-pop choreography and to supplement the system include the NFT.

Clothing is intimately intertwined with daily lives as every individual relies on it. The pervasive issue of plagiarism in the fashion industry has led to an increased demand to protect intellectual property rights. Currently, studies on the protection of fashion design intellectual property rights in China remain in the exploratory stage and warrant further investigation. This paper addresses the issue in two parts. The first part contains an analysis of the theoretical foundation for the protection of fashion design copyrights. It is further divided into three subsections. The first subsection primarily examines the concept of copyrights and laws. The second subsection focuses on the concept of fashion design copyrights and laws. The third subsection analyzes copyright laws concerning fashion designs in China. The second section offers an analysis of infringement cases involving fashion designs published during the Baiyi Cup Intellectual Property Case Summary Writing Competition held in China in 2023. It outlines the shortcomings of the current Chinese copyright laws regarding the protection of fashion designs, and proposes measures for improvement. This study argues that the institutional framework for intellectual property rights in the Chinese fashion industry should align with practical considerations and explores suitable legal regulations and how they relate to specific circumstances in China. Besides refining the legal framework, fashion designers and enterprises must take measures to entablish the intellectual property rights of their clothing brands.

Meaningful logos or random sequences have been used in the current digital watermarking techniques of 2D bar code. The meaningful logos can not only be created by copyright holders based on their unique information, but are also very effective when representing their copyrights. The random sequences enhance the security of the watermark for verifying one's copyrights against intentional or unintentional attacks. In this paper, we propose a new watermarking technique taking advantage of Data Matrix as well as encryption keys. The Data Matrix not only recovers the original data by an error checking and correction algorithm, even when its high-density data storage and barcode are damaged, but also encrypts the copyright verification information by randomization of the barcode, including ownership keys. Furthermore, the encryption keys and the patterns are used to localize the watermark, and make the watermark robust against attacks, respectively. Through the comparison experiments of the copyright information extracted from the watermark, we can verify that the proposed method has good quality and is robust to various attacks, such as JPEG compression, filtering and resizing.

본 논문에서는 오디오 컨텐츠 저작권 보안을 위하여 MP3 공격에 강인한 워터마킹 방법을 제안한다. 일반적인 주파수 도메인에서의 워터마킹 방법인 Cox의 스프레드 스펙트럼 방법에서는 DCT후 값이 큰 저주파수의 계수에 순차적으로 워터마크를 삽입하였다. 임의의 주파수 계수에 삽입하는 방법은 효과적이지 못하므로, 본 논문에서는 심리음향 모델을 분석하여 MP3 공격시 손실이 적은 주파수 계수에 적응적인 함수를 적용하여 가중치를 부여한 후 계수에 워터마크를 삽입하는 방법을 제안한다. 다양한 음원에 대하여 실험한 결과, 제안한 방법은 기존의 방법들에 비해 워터마크의 보존하고 원본 음원의 왜곡을 줄이는 두 가지 측면 모두 좋은 결과를 나타내었다.
