MPEG-21 is an open standard framework for creation, delivery and consumption of digital content in interoperable and rights-managed and protected way. Focusing on DRM technologies, this paper covers with concept and ongoing activities of MPEG-21's parts - Digital Item Declaration which is the base unit of trade and delivery, Digital Item Identification, Intellectual Property Management & Protection, Rights Data Dictionary, Rights Expression Language, Persistent Association Technology, Event Reporting, and so on.

Current technologies on digital rights management (DRM) have focused on security and encryption as a means of solving the issue of unauthorized copying, that is, locking the content and limiting its distribution to only purchasers. But, illegal content copy should be protected not only from purchasers but also from other principals such as media distributors and content providers. In this paper, we designed and implemented end-to-end digital lights management system that can cover a content protection on the overall value-chains of content distribution. Proposed system provides content protection and secure management of digital rights in creator, provider, and distributor like in purchaser. Accordingly it can provide an environment protecting each principal's digital rights and prohibiting illegal usage of content.

The rapidly increasing use of the Internet and advancement of the communication network, the explosive growth of digital contents from personal home pages to professional information service the emerging file exchange service and the development of hacking techniques . these are some of the trends contributing to the spread of illegal reproduction and distribution of digital contents, thus threatening the exclusive copyrights of the creative works that should be legally protected Accordingly, there is urgent need for a digital copyright management system designed to provide centralized management while playing the role of bridge between the copyright owners and users for smooth trading of the rights to digital contents, reliable billing, security measures, and monitoring of illegal use. Therefore, in this study, I examined the requirements of laws and systems for the introduction of the centralized management system to support smooth distribution of digital contents, and also researched on the current status of domestic and international centralized management system for copyrights. Furthermore, 1 tried to provide basic materials for the standardization of digital contents copyright management information through the examination of the essential elements of the centralized digital contents management such as the system for unique identification the standardization for data elements, and the digital rights management (DHM) .

인터넷의 발달은 전통적인 자연 발생적인 시장에 의한 상거래를, 기술에 의한 안전하면서 세계 시장을 쉽게 접근할 수 있는 전자상거래 구조를 제공하고 있다. 현재 전자상거래의 대상은 실물에 대한 상거래와 디지털 컨텐츠에 대한 상거래로 크게 분류할 수 있으며, 실물에 대한 상거래는 전통적 상거래 방식이 컴퓨터로 바뀐 상황이라고 볼 때, 디지털컨텐츠에 대한 상거래 즉, D-Commerce에 대한 상거래의 개념이 도래하고 있다. 디지털 컨텐츠의 상거래에 필요한 요소 기술에 대한 연구, 그리고 특히 새로운 유통 비즈니스 모델에 대한 연구가 필요하다. 디지털 컨텐츠는 생성, 가공, 유통, 분배 둥의 측면에서 많은 장점을 갖는 반면, 복사를 여러 번해도 원본의 품질에 손상 없이 쉽게 복사 될 수 있다는 것이 디지털 저작권 보호에 커다란 문제점으로 대두되고 있다. 디지털 저작권권리(Digital Rights Management: DRM)은 디지털 콘텐츠의 보호와 적절한 유통체계를 설립하여 안전하게 상거래를 할 수 있게 하기 위한 새로운 기술이다. XrML은 권리(Right)를 명시하는 언어로써 디지털 컨텐츠와 그에 따른 서비스들을 사용할 수 있는 권리와 조건들을 명시해준다. XrML은 현재 디지털 저작권권리(Digital Rights Management: DRM)에 가장 많이 쓰이고 있는 Rights Language이다. XrML은 ContentGuard가 개발한 DRM 서술 언어로 전 세계 산업계 표준으로 추진하기 위하여 파트너 회사 확대, 기능 확장, 무료/공개 형식으로 보급을 추진하고 있다.

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 PKI security method, real time action monitoring for user, data security for itself.

This study investigates the effect of the update Digital Rights Management (DMR) strategy on a firm's profit. The model developed by Kim and Talalayevsky (2007) is applied to the case of two representative Korean software firms. Specifically, this study shows the model suggested by Kim and Talalayevsky (2007) fits the reality of Korean firms' DMR strategies. Based on the result, this study makes some implications to managers and policy makers.

DRM(Digital Rights Management) is a technology that manages secure distributions and copyrights of digital contents on the Internet. It is general giving the rights to use the encrypted contents that are downloaded by a simple authorization process in the existing DRM system. Once this is done you are allowed to access. In this paper, we use RTP(Real-time Transport Protocol) for end-to-end real-time data transmission. And the system is designed to make it Possible to Protect copyrights and to distribute contents with safety through periodic authentication. We implemented DRM system to stand this basis. The proposed system vests only authorized users with authority to access the license. Hence it prevents contents to be distributed and copied illegally on networks.

There have been researches into digital Watermarking technology or Fingerprinting vigorously to safeguard Protective rights for knowledge and poverty for digital contents. DRM(Digital Rights Management) is not only Protective rights for knowledge and poverty, but also management and systems that are necessary to put out, circulate and use for contents. This paper proposes two kinds of ideas. One is protecting contents from illegal acts such as illegal copies when the contents are in the process of circulation. The other is the protocol that can give users convenience. Hidden Agents are used so that contents are protected from illegal copies and illegal use in the contents and cuts off those illegal acts. The Agent will be installed without any special setup. In addition, it can replace roles of Watermarking as a protection. Therefore, this paper shows the solution of illegal copies that happens frequently.

Digitalized multimedia contents is changing active digital contents in form passed from manufacturer directly to consumer though digital network of high speed, also face with big problem that is protection of rights to protect digital contents, to protect those and effort to active digital contents process height. Also, in situation that require change to more efficient system, the efficiency of rights document that is basic intermediate to be used in business of digital contents field is emphasized. Therefore, the design of common business model to share contents that have same purpose without depending on specific system to offer contents with another system is required. This paper designed adaptable rights business model to general digital contents, and designed and implemented rights document editing system to editable document for Right management according to designed business model.
