The widespread use of the Internet brings about the issue regarding intellectual property and copyright. This paper describes DRM (Digital Rights Management) technologies and their related issues. Current approaches on DRM architecture are examined first. Based on the review, we discuss some security issues that would be essential to design security mood and architecture appropriate for DRM. Having these security issues in mind, we propose a new approach on DRM security architecture, based on our trust model.

Beyond the digital world from the analog age, the contents are very easily copied under the illegal conditions and these are rapidly distributed by the information super highway. The increase of illegal usage and conflict in digital content market would diminish motivation of creators for their work, furthermore break down digital content market on cyberspace. Watermarking technology support to the legal users by the protection technique based on the digital content copyright protection method(DRM). Most of previous digital watermarking have embeded to the content. In this paper, we researched the standardization of digital rights management and developed more efficient watermark embedding method.

Recently, the studies of contents protection technique are getting popular in the field of internet DRM(Digital Right Management). But, authentication process of digital contents is different from each implementation. Also, protection technique for the contents rights intrusion adapts each other methodologies. We survey the modeling and system of DRM such as DOI, INDECS, MPEG-21, XrML, and OPIMA standard in this paper.

In this paper, we have made an analysis of dCollection license system and have presented the development subject based on various case study of digital rights Management( DRM ) under domestic and abroad Open Access circumstances. For this study, fist we made an investigation into the concept and the technical component of the copyright, license and DRM that act as obstacle to open access. It is hoped that the first study will be able to help people better understand the relationship between the related technique and Open Access System. Second we analyzed Creative Commons, RoMEO, Dspace system as abroad cases and Kyungpook National University's DRM system and Seoul National University's DRM system as domestic cases for copyright protection under open access circumstances. finally we will face up to the domestic open access reality and plan the future by presenting the development subject through dCollection license system analysis.

인터넷의 확산과 더불어 디지털 컨텐츠의 유통도 확산되었다. 그러나 디지털 컨텐츠들은 쉽게 원본과 똑같은 품질로 복제할 수 있으며, 인터넷을 통해 빠르게 이동이 가능하고 사용자들은 얼마든지 불법으로 이용할 수 있다는 것이다. 최근 국내·외에서 이러한 문제를 해결하기 위해 디지털 컨텐츠들을 보호하고 관리할 수 있는 DRM 기술이 활발히 연구 중이다. DRM 기술은 암호화 기술을 이용하여 허가되지 않은 사용자로부터 디지털 콘텐츠를 안전하게 보호하고 디지털 컨텐츠 저작권 관련 당사자의 권리 및 이익을 지속적으로 보호 및 관리 할 수 있는 기술이다. 본 논문에서는 저작권 보호를 위해 안전한 DRM 메커니즘을 제안한다.

This paper tries to solve the problems which previous methods have such as the WCDRM(Watermark and Cryptography DRM) and the model using smart card for protecting digital contents. This study provides a contents distribution model to protect the rights of author, distributor, and user as well as user's information by using technologies such as cryptography, DRM(Digital Right Management), access control, etc. The proposed system is evaluated as the most safety model compared with previous methods because it not only solves the problems which the previous methods have, but also protects four type of risks such as use of contents which other mobile devices download, the attack on the key to decode the message, the attack on leaking the contents, and the internal attack such as an illegal reproduction.

This paper propose an interested digital rights protection scheme 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.

As widespread of using digital documents in various fields, control the usage of digital document is needed. So, Digital Rights Management(DRM) will become a key component of digital document system, but absence of proper digital document DRM system, there is a real risk to lose important information when a hacker achieved intrusion in important system. This paper designs and implements digital document DRM system based on OMA(Open Mobile Alliance) DRM model and OpenOffice. We considered being a digital document DRM system to contain appropriate solution of security and document compatibility.

디지털 컨텐츠의 생산과 수요가 폭발적으로 증가함에 따라 컨텐츠에 대한 지적 재산권 및 수익 창출에 대한 중요성이 대두되었다. 이를 위해 디지털 컨텐츠 자체에 저작권을 보호살 수 있는 기능을 부여하는 기술인 DRM이 개발되었다. 본 논문에서는 DRM(Digital Rights Management)의 영역에 속하는 디지털 컨텐츠 접근을 제어하기 위한 기술 중에서 이미지 컨텐츠에 대한 불법적인 캡쳐 방지를 위한 모델을 제안한다.

인터넷의 고속화, 대용량화로 디지털 컨텐츠의 사용이 증가하고 있다. 디지털 컨텐츠는 비 손실 복제, 디지털 정보의 접근 용이성, 쉽고 빠른 배포 가능, 매우 적은 복제 비용 등의 특성으로 불법적인 복제와 배포가 널리 행해지고 있다 이에 대한 대책으로 DRM(Digital Rights Management)에 대한 많은 연구가 이루어지고 있다. 최근 모바일 Device를 이용한 디지털 컨텐츠의 사용이 늘고 있다. 모바일 환경에서 디지털 컨텐츠를 이용하기 위해서는 모바일 환경의 여러 가지 조건을 고려해야한다. 본 논문에서는 X9.59 지불프로토콜을 이용하여 보다 안전하고 편리하며 모바일 환경에서도 적용 가능한 DRM기반 컨텐츠 유통 시스템을 설계하고 구현한다.
