  • DRM(Digital Right Management), which realize the controllability of intellectual right in the process of transactions with economically feasible cost, may cause critical changes in the distributions of digital contents. This Paper takes notice of the concept of 'Super Distribution' in which every user can be the core of the distribution and the possibility of usingvarious price structures by introducing DRM. We reviews that Super Distribution can increase the demand of digital contents by decreasing the information cost in the user aspect, and it can also diminish the distribution cost dramatically in the provider aspect. Also, DRM may allow various types of pricing which use different criteria such as the number or duration of usage. The variety in price structure can increase not only the profit of provider but the utility of consumer. These characteristics of DRM, as a whole, increase the efficiency of distribution and make the providers differentiate their services.

  • To make the DRM technology protect adequately the copy right of digital contents, DRM software should have high quality and no defects when DRM is added to digital contents. It can be a basis for the effective protection of the copyright of digital contents to develop a quality evaluation model of DRM SW. First of all, the security of DRM SW is the most critical quality characteristic that DRM software must have. In this paper, we conducted research on how to measure the quality of security of DRM SW.

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

  • Today, Digital Right Management (DRM) is used to protect copyrights of digital contents from illegal reproduction and redistribution. Unfortunately, current DRM systems are causing user's discomfort because of lack of mutual compatibility. In order to overcome this drawback, technologies for interoperability of heterogeneous DRM systems are developing. In this paper, we study the protection profile for conversion technologies of heterogeneous DRM systems, using the Common Criteria. Especially, this paper is written by reuse of the existing protection profile. Therefore, performance analysis reveals that efficiency of time and cost is significantly improved. This protection profile can be used by contents provider and administrator who manage user's copyrights to reference data for copyright protection.

  • 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.

  • In recent years, advanced in digital technologies have created significant changes in the way we reproduce, distribute and market Intellectual Property (IP). DRM for multicast contents is complicated risk, the further technology development and human demand, this approaching is still being researched by the scientist and all by the company which is conducting in piracy management reduced, and every country has national policy to make this consortium to limit piracy properties, based on this paper research development, just only two approaching to reduce piracy in DRM they are Industrial Property (IP) and Copyright. In this paper, we are not only figuring and analyzing about the processes to reduce and limit the piracy and unprotected copy law but also describing about the encryption process, watermarking and digital signature process algorithms. The basic concepts of this encryption process for web-based multicast content in DRM are implemented in Java. We conduct this method is a computerized through web based application system approaching to reduce unprotected copy and piracy. Which is used in DRM for multicast content in every section, by providing a fundamental in information technology development, we believe this research is reliable to prove that is unprotected copy, and piracy can be reduced by protecting with this paradigm.

  • In this paper, we design and implement the UHSNS-DRM(Ubi-Home Smart Multimedia Streaming-Digital Right Management) in Ubi-Home. The proposed system support flexible distribution platform for digital content copyright protection and management in Ubi-Home. This system also can provide multimedia streaming service to authorized users who are using PC, STB, PDA, and Portable Device, etc. Furthermore, we adopt concept of domain authentication and it help to improve the efficiency of license management for all devices in Ubi-Home. We design user's location recognition algorithm in order to provide intelligent services. Of course, this algorithm is applied for the proposed system. Start after striking space key 2 times.
