Abstract-Current Digital Rights Management (DRM) systems support only two-party systems, involving the package server and purchaser. However, for a scalable business model of transacting digital assets, a multi-party DRM system is often necessary which involves more than one distributors, who can promote and distribute the content in regions unknown to the package server. We propose a key management scheme for a DRM system that involves more than one distributors with the DRM client's flexibility of choosing a distributor according to his own preference. For instance, a mobile DRM client may contact to a distribution server who is nearest to him by location or who offers promotions/discounts on the price or offers more commissions. In our scheme, the package server does not trust the distribution servers or the license server. The encrypted digital content sent by a package server can only be decrypted by the DRM client who has a valid license and is protected from attacks by other parties/servers in the system. Moreover, we use Identity-Based Encryption (IBE) that incurs less computation cost and storage as certificate managements are not necessary and certificate verifications are no longer needed. These features make our DRM system suitable for more effective business models/applications with the flexibility in deciding a wide range of business strategies as compared to the existing works.

“…It is impossible to control and manage content which is distributed beyond the scope of the principáis concerned. Finally, when breach of contract occurs it is difficult to forcefully control content distribution and to verify the facts in order to establish the breach of contract (Cohén, 2003;Jeong, Yoon, & Ryou, 2005).…”

ARTICLE INFO ABSTRACT Keywords:Current studies on Digital Rights Management (DRM) have focused on controlling access to and copies Digital rights 0 f contents, centered exclusively on the end of the valué chain (end users). This focus has been oriented Platform towards security and encryption as a means of solving the issue of ¡Ilegal copying by purchasers. In this paper, we propose End-to-End Digital Rights Management (E2E DRM) that involves the protection of the content throughout the entire valué chain. This concept is given form in the new technologies for representing intellectual property (IP) which, in a secure and unequivocal manner, identify the content at each point in the valué chain: from the author to the end user, the content is identifiable in any of the transactions and statuses through which it passes. The key concept which E2E DRM must provide is not only the governability of access and copying, but also that of all the processes associated with the content business. We establish an E2E DRM model and architecture, and propose the R&D management of its design and implementation that makes it possible to protect content from content creator to purchaser. Finally, the paper also analyzes their impact from a global perspective.

“…As digital technology and communication technology are becoming more common, end users can create, modify and distribute digital content with little effort. The convenience of digital content has increased the demands of the content, but because of characteristic of digital content which can be duplicated unlimitedly, the issues on security and copyright [2][12] have been raised frequently. Especially, GIS data has been extended to Geo-Contents concept which includes digital contents related to geographic information and it is expanded into many different forms of data.…”

GIS data is digital content that requires high initial production cost and it is transformed into different digital content according to its usage or access level. The convenience of digital content has increased the demands of the content, but because of characteristic of digital content which can be duplicated unlimitedly, the issues on security and copyright have been raised frequently. This paper proposes multi-level access control using Delta Compress Algorithm and by granting access control based on usages and permissions of content, it prevents the illegal use of GIS data which will protect and maintain digital contents consistently. Multi-Level Access Control using Delta Compress proposed in this paper is applied to all digital content in the same way and the same application is possible to Raster Image without additional work for file format.
