This paper presents a review of the OMA DRM Version 2.0 profile of the ODRL REL. It looks at the decisions made by the OMA DRM working group and offers alternatives. The lessons are important to both the ODRL Initiative and to other groups developing profiles of the ODRL REL. Index terms ODRL, DRM Open Mobile Alliance, REL Profile

Acquiring digital media over the Internet has become commonplace in recent years. Companies are looking into ways to sell their content (music, movies, etc.) over the Internet without the buyer being able to further distribute the work. Digital Rights Management (DRM) systems address this; their main goal is to enable authorised users to access a version of digital content on the terms for whic...

This work describes two different configurations of syngas production processes using a combination of steam methane reforming (SMR) and dry reforming of methane (DRM). The ideal SMR+DRM process ensures the maximum product yield, the heat-integrated SMR+DRM process fulfills the maximum heat recovery, and the stand-alone SMR+DRM process effectively suppress net CO2 emissions. Through kinetic mod...

Performing digital rights management (DRM) on mobile distribution services encounters many technical problems. Major problems include privacy and trust, coordination and interoperability, security, license management, DRM operations, and payment. This paper proposes a generic DRM framework to tackle these problems. The proposed framework consists of (1) an operational mobile infrastructure; (2)...

Preserving the customer’s privacy has to be a major concern when implementing a commercial DRM system. In [12] a privacy-preserving digital rights management (DRM) architecture based on the widely used Open Mobile Alliance (OMA) DRM [17] specification for mobile devices has been suggested. In this paper the design of a possible implementation of the proposed architecture is explained which uses...

In this paper, we first propose a novel Public License Infrastructure (PLI) that uses cryptographic threshold secret sharing schemes to provide decentralized public license services for the Digital Rights Management (DRM). This distributed PLI replaces the centralized license server in a conventional DRM system. PLI offers many advantages such as intrusion and fault tolerance, flexibility, scal...

Due to its ability to solve all main problems associated with digital goods, Digital Right Management is the favourite option used by companies to tackle piracy. The aim of this article is to discuss the consequences of DRM for consumers, firms and society. The rationales of DRM are discussed and the expected benefits for firms are presented. It is shown that the advantages brought by DRM to fi...
