Sharing Digital Rights With Domain Licensing, N. P. Sheppard, R. Safavi-Naini
Faculty of Informatics - Papers (Archive)
Sharing of multimedia content is a common practice that, combined with appropriate business models, need not be detrimental to the interests of content providers. Existing digital rights management systems, however, support only relatively limited sharing of content between multimedia terminals, resulting in inconvenience and frustration for end-users of rights-managed content. In this paper, we propose to combine the notion of an "authorised domain" with an "environment role" to permit end-users to share access to multimedia content within the constraints expressed in a domain licence. We describe how a variety of different business models can be supported using domain licences, and …

We describe and compare three different modes in which Heimdall might operate.

A number of authors have observed a duality between privacy protection and copyright protection, and, in particular, observed how digital rights management technology may be used as the basis of a privacy protection system. In this paper, we describe our experiences in implementing a privacy protection system based on the Intellectual Property Management and Protection ("IPMP") components of the MPEG-21 Multimedia Framework. Our approach allows individuals to express their privacy preferences in a way enabling automatic enforcement by data users' computers. This required the design of an extension to the MPEG Rights Expression Language to cater for privacy applications, and …
