  • 타인의 저작물 일부 또는 전부를 마치 자기의 창작물인 것처럼 몰래 사용하는 표절과 스마트 환경에서 다양한 형태로 발생하고 있는 저작권 침해 행위는 우리나라가 문화 선진국으로 도약하기 위해 최우선적으로 해결해야 할 과제로 부상하고 있다. 본 논문에서는 스마트 환경에서 다양한 스마트 기기들을 가장 많이 이용하고 있는 대학생들을 대상으로 표절과 저작권 침해 실태를 조사하여 분석하고, 표절과 저작권 침해를 예방하기 위한 기본적인 교육 방안을 고찰하였다. 대학생들의 표절과 저작권에 대한 인식이 매우 낮고, 초중등학교를 거쳐 대학생활을 하는 과정에서 진행되어 온 표절과 저작권 침해 실태도 매우 심각한 것으로 나타났다. 이러한 문제를 해결하기 위해 본 논문에서 제안한 대응 방안을 통해 표절과 저작권 침해에 대한 인식의 개선과 각종 부작용의 예방이 가능할 것으로 확인되었다.

  • Free and open source software (FOSS) has created a large pool of source codes that can be easily copied to create new applications. However, a copy should preserve copyright notice and license of the original file unless the license explicitly permits such a change. Through software evolution, it is challenging to keep original licenses or choose proper licenses. As a result, there are many potential license violations. Despite the fact that violations can have high impact on protecting copyright, identification of violations is highly complex. It relies on manual inspections by experts. However, such inspection cannot be scaled up with open source software released daily worldwide. To make this process scalable, we propose the following two methods: use machine-based algorithms to narrow down the potential violations; and guide non-experts to manually inspect violations. Using the first method, we found 219 projects (76.6%) with potential violations. Using the second method, we show that the accuracy of crowds is comparable to that of experts. Our techniques might help developers identify potential violations, understand the causes, and resolve these violations.

  • 전 세계적으로 각종 산업 분야를 불문하고 소프트웨어 개발 시 오픈 소스 소프트웨어가 다양하게 활용되고 있다. 이러한 오픈 소스 소프트웨어는 자유로운 사용에 대한 권리뿐만 아니라 그에 따른 책임을 라이선스(license) 형태로 요구한다. 오픈 소스 소프트웨어 라이선스는 오픈 소스 소프트웨어 개발자와 이용자 간의 조건 범위를 명시한 계약이기 때문에 개발자가 규정한 라이선스를 지켜야 하며 이를 위반할 경우에는 저작권 침해가 발생하고, 이에 대한 책임을 지게 된다. 특히, 새로운 소프트웨어 개발 시 기존에 개발된 오픈 소스 소프트웨어를 활용하는 경우, 각 코드의 라이선스가 양립성(compatibility)문제를 발생시키지 않고 서로 호환되는지 확인해야만 한다. 그러나 이러한 철학에 반하여 양립성 문제 관련 사건들이 다수 발생하고 소송으로 이어지기도 하면서 원활한 오픈 소스 소프트웨어 생태계에 악영향을 미치고 있다. 따라서 본 논문에서는 사용하고자 하는 오픈 소스 소프트웨어들 간에 오픈 소스 규칙을 준수하고 라이선스 양립성 문제가 발생하지 않는지 식별할 수 있는 새로운 기법인 OSLC-Vid를 제안한다. 이렇게 제안된 기법은 실제 오픈 소스 소프트웨어를 활용하여 위반사례 식별 성능을 검증하였다.

  • BitTorrent는 다수의 파일 공유자들로부터 조각파일을 전송 받아 하나의 완전한 파일을 완성할 수 있는 파일 공유 및 전송과 관련된 혁신적인 프로토콜이다. 그러나, 불법 또는 저작권과 관련된 비디오 데이터들이 임의로 배포되는 범죄행위가 발생하는 것이 현실이다. BitTorrent 상에 데이터에 대한 저작권 단속의 어려움은 데이터의 전송형태가 완전한 파일 형식이 아닌 조각 파일 형태로 전송된다는 점이다. 따라서, BitTorrent에서 얻어진 조각파일에서 디지털 콘텐츠를 복원하고, 저작권 위반 여부를 판단하기 위해서는 디지털 콘텐츠의 파일 형식에 대한 분류 과정이 선행 되어야 한다. 본 연구에서는 디지털 파일의 형식을 분류하기 위한 방법으로서 조각파일의 히스토그램 차분을 특징 벡터로 하는 SVM 분류기를 제안 하였다. 제안한 분류기는 3종류의 비디오 파일 형식에 적용하여 분류율로 성능을 평가하였다.

  • In spite of the rapid development of the public network, the variety of network-based developments currently raises numerous risks factors regarding copyright violation, the prohibition and distribution of digital media utilization, safe communication, and network security. Among these problems, multimedia data tend to increase in the distributed network environment. Hence, most image information has been transmitted in the form of digitalization. Therefore, the need for multimedia contents protection must be addressed. This paper is focused on possible solutions for multimedia contents security in the public network in order to prevent data modification by non-owners and to ensure safe communication in the distributed network environment. Accordingly, the Orthogonal Forward Wavelet Transform-based Scalable Digital Watermarking technique is proposed in this paper.

  • Transmitting visual information over a broadcasting network is not only prone to a copyright violation but also is a forgery. Authenticating such information and protecting its authorship rights call for more advanced data encoding. To this end, electronic watermarking is often adopted to embed inscriptive signature in imaging data. Most existing watermarking methods while focusing on robustness against degradation remain lacking of measurement against security loophole in which the encrypting scheme once discovered may be recreated by an unauthorized party. This could reveal the underlying signature which may potentially be replaced or forged. This paper therefore proposes a novel digital watermarking scheme in temporal-frequency domain. Unlike other typical wavelet based watermarking, the proposed scheme employed the Lorenz chaotic map to specify embedding positions. Effectively making this is not only a formidable method to decrypt but also a stronger will against deterministic attacks. Simulation report herein highlights its strength to withstand spatial and frequent adulterations, e.g., lossy compression, filtering, zooming and noise.

  • In the intellectual based society of the 21th century, intellectual property of nation and enterprise management has been the key element of nation's competitiveness and development. Therefore in countries like Korea, China, and many other countries, intellectual property of advancement strategy are being constructed and intellectual properties are protected at national level. Top priority task of protecting the intellectual property is to efficiently resolute intellectual property right disputes. Considering the nature of intellectual property right and arbitrage system, arbitration to solve intellectual property disputes is realistically the best method. However, not all cases of them are qualified. In order to relieve the intellectual property disputes through arbitration, qualification must be obtained. During the process, generally and globally, intellectual property right dispute is evaluated by three parts, intellectual property right contract dispute, intellectual property right violation dispute, and intellectual property right validity dispute. Based on UN's "Convention on the Recognition and Enforcement of Foreign Arbitral Awards Agreement" in 1958, June 10th, in New York, both arbitrage organization and judgment can be approved in both Korea and China countries. However, as of today, there is a big gap of arbitration qualification between two countries, which can be troublesome if intellectual property right disputes arise. For instance, in Korea, intellectual property right contract disputes and intellectual property right violation disputes are both generally accepted as arbitration qualification. However for intellectual property right validity dispute, arbitration qualification is only accepted for non-registered intellectual property as in copyright entity. It does not apply to other registered intellectual property right as in patents. In China, arbitration qualification is accepted for intellectual property right contract dispute, and also accepted for intellectual property right violation dispute to copyrights but restricted to others. As for intellectual property right validity dispute, arbitration qualification is completely denied. Therefore, when there is an intellectual property right dispute between Korea and China, the biggest problem is whether China will accept arbitrage judgments made in Korea. Theoretically, arbitrage judgement made in Korea should be also accepted in China's court. However, considering the criticism of China's passive nature of arbitration qualification for its own local intellectual property right disputes, it's very unlikely they'll actively accept arbitrary judgment made in foreign countries. Korea and China must have a more open minded approach for intellectual property disputes and arbitration qualification. Base on WTO's Intellectual Property Right Agreement, it's being defined as private right. Therefore, sovereign principle should be the basic principle of solving intellectual property right disputes. Currently, arbitration qualification is expanding internationally. So both Korea and China must also follow the trend expand the arbitration qualification with a more open minded and forward looking approach, for the good of intellectual property disputes.
