Import/export in digital rights management

Abstract

The inherently controlled nature of digital rights management systems does little to promote inter-operability of systems provided by different vendors. In this paper, we consider import and export functionality by which multimedia protected by one digital rights management regime can be made available to a multimedia device that supports a different digital rights management regime, without compromising the protection afforded to the content under the original regime. We first identify specific issues to be addressed by developers of digital rights management import/export regimes and outline a variety of methods by which these regimes may be implemented. We then apply our observations to the specific example of import and export of content between the digital rights management regimes defined by the Motion Picture Exports Group and the Open Mobile Alliance.

An interoperable security framework for connected healthcare

“…They also show that digital rights management can be used to control the purpose for which the data is being used and for providing session management by integrating it with workflow information and states. In [2], Safavi-Naini et al provides an interoperability framework for importing or exporting multimedia content protected by one DRM system into a multimedia device that supports a different DRM system. In [1], Kalker et al presents an interoperability framework that allows multiple DRM systems to seamlessly work together while at the same time requiring minimal modification to existing DRMs.…”

Digital Rights Management

“…Other important aspects are legal and financial implications of allowing content that is protected under one DRM system to be used under a second DRM system. In practice an inter-operability framework addressing these issues must be in place [91]. DRM-protected information is distributed in a protected form that is, by design, inaccessible to any entity that does not conform to the DRM vendor's specification.…”

On the operational semantics of rights expression languages

“…Some authors have proposed that abstract rights models be used to promote interoperability by translating expressions in one language to expressions in another language [12,18,19], using the abstract model as an intermediate representation. It seems unlikely that the semantics proposed in this paper could be used in such a fashion, since it would require the output of the compiler on the first language to be de-compiled into the second language, and we cannot see any easy way of doing this.…”
