인터넷과 컴퓨터 기술의 발달로 멀티미디어 컨텐츠의 불법유통이나 복제가 심각해지면서 디지털 저작물의 저작권 보호를 위한 기술들이 개발되기 시작하였다. 디지털 워터마킹 기술은 이러한 저작권 보호기술의 하나로 원본 컨텐츠에 저작권자에 대한 정보를 은닉함으로써 저작권자를 확인시켜주고 불법복제나 유통여부를 가려주는 기술로 개발된 것이다. 디지털 워터마킹 기술이 필요한 정보를 은닉한다는 측면에서 정보은닉 기술의 하나로 활용이 가능하며, 이는 단순히 저작권 보호 이외의 분야에 대해서도 응용이 가능하다는 것을 나타낸다. 본 고에서는 오디오 워터마킹 기술을 이용하여 중앙 방송국과 지방 방송국간의 방송전환 시점을 자동으로 검지하는 데 응용하는 예와 신분증에 있어서의 위변조를 방지하기 위한 응용 예를 다루었다.

This study is about the copyright policies by Korean government and the revision of the article 31 library exemption provision in the Copyright Act of Korea for noncommercial scholarly works considering through cases of copyright disputes occurred in Korea during the $2005{\sim}2007$. This study proposes that works not for sale including thesis should be exempted from the copyright compensation in the article 31(5) in the Copyright Act of Korea based on the properties of noncommercial scholarly works and the regulations on works for not for sale in the current Korean copyright act. Also, this study reports that the copyright trust of scholarly articles by the copyright trust management agency is illegal in part and the government which has a duty to direct it has to control the illegal actions. Finally, this study proposes that noncommercial scholarly works such as thesis and scientific articles are to be open access and Korean government should develop open policies for them.

Free Use License is an effective means of allowing many people to freely use works in the public domain. It can also prevent copyright infringement problems. This article analyzes the current service and domestic and foreign technology as it applies to free use license. It then proposes a plan which incorporates diverse requirements including technical aspects. Strategies are formulated from the technical, service and the resources connection perspectives for applying license in addition to searching and using licensed works. This article suggests a three-stage utilization plan to encourage the use of free use license. First, a connection plan between digital archiving and free use license, is developed. Then, a connection plan between UCI identifier and free use license is developed, and finally, the plan for the use of public resources is presented.

As the logistic environment of digital contents is rapidly changing, the protection of the digital rights for digital content has been recognized as one of critical issues. Digital Right Management(DRM) has taken much interest Internet Service Provider(ISP), authors and publishers of digital content as an interested approach to create a trusted environment for access and use of digital resources. This paper propose an interested digital rights protection scheme using license agent to address problems facing contemporary DRM approached : static digital rights management, and limited application to on-line environment. We introduce a dynamic mission control technology to realize dynamic digital rights management. And we incorporate license agent to on- and off-line monitoring and tracking. The proposed system prevent illegal access and use by using PBD security method real time action monitoring for user, data security for itself.

The information of world is most likely to be created as digital data. These digital productions need some legal protection mechanisms or techniques because users can illegally use them. Thus many researchers are developing various techniques. Currently most techniques are focusing on the physical and chemical methods like disk inspection for taking legal evidence about production infringement. This paper has developed a computer forensics-based copyrights protection system capable of detecting and notifying disobedience facts when user uses illegally a production. Furthermore if the user infringes continually the production the system stores the infringement facts to take the legal evidence by mapping to law for intellectual property right. The technique can protect data from digital evidence manipulation or destruction.

Sharing copyrighted files without copyright holder's permission is illegal. But, a number of illegal file sharers using BitTorrent increase. However, it is difficult to find appropriate digital evidences and legal basis to punish them. And, there are no framework for digital investigation of illegal sharing using BitTorrent. Additionally, role of server in BitTorrent had been reduced than server in conventional P2P. So, It is difficult to apply investigation framework for illegal sharing using conventional P2P to investigation process of illegal sharing using BitTorrent. This paper proposes the methodology about punishing illegal sharer using BitTorrent by suggesting the digital investigation framework.

As UCI (Universal Content Identifier) identification system becomes a national standard for content distribution, many digital contents are distributed through UCI identification system. However, problems associated with copyright infringement and copyright contracts occur due to lack of copyright information. ICN (Integrated Copyright Number), a code system developed for copyright management, includes copyright-related information for the purposes of usage settlement and accounting, illegal usage monitoring, and content filtering. ICN, however, has no information about distribution and content properties. Therefore, the linkage and integration between UCI and ICN can be a basis for the transparent and effective distribution of digital contents. In this paper, we propose a model for linking and integrating UCI and ICN, developing the efficiency in the value chain of each identified system by analyzing political factors and key technical elements between the two identification systems.

There are lots of limits on preventing illegal transaction of digital contents by existing DRM(Digital Right Management) methods because of illegal download and share of contents, which is resulted from advanced information technologies, development of cloud services, and smart instruments. In the other hand, the number of creators based on one person, in the area of music, webtoon, digital magazine and video, is increasing. As a result, it is needed that the necessities of digital contents transaction under the condition of convenience and efficiency through licence and management of contents to protect copyright of contents and to increase the transaction of digital contents. Therefore how to promote the transaction of digital contents should be studied by way of research analysis of contents market through interviewing experts in business.

Creative works such as webtoon and web novel are part of property rights. However, illegal copies of them are distributed on the internet easily, which raises social issues in today's society. In order to tackle these problems, this paper proposes and presents a blockchain based copyright management system that ensures forgery prevention, robust security features, improving trading performance, cost-effective, and enhanced visibility. The system allows a user to register creative works formally just the same as before registration and also to register simple creative ideas just anytime. In the latter case, if an idea or a thought flashes across through somebody's mind, he or she can register it to the system immediately without formal registration process and afterward, can utilize a way to prove its originality through the system. Regarding large size images and video files of creative works, the system reduces data size and storage volume sharply to be processed by network entities by storing original creative works separately and including only the hash result of creative works to the transactions.
