Abstract:
The thesis is concerned with Digital Rights Management (DRM), and in particular with DRM for networks of devices owned by a single individual. This thesis focuses on the problem of preventing illegal copying of digital assets without jeopardising the right of legitimate licence holders to transfer content between their own devices, which collectively make up what we refer to as an authorised domain. An ideal list of DRM requirements is specified, which takes into account the points of view of users, content providers and copyright law. An approach is then developed for assessing DRM systems based on the defined DRM requirements; the most widely discussed DRM schemes are then analysed and assessed, where the main focus is on schemes which address the concept of an authorised domain. Based on this analysis we isolate the issues underlying the content piracy problem, and then provide a generic framework for a DRM system addressing the identified content piracy issues. The defined generic framework has been designed to avoid the weaknesses found in other schemes. The main contributions of this thesis include developing four new approaches that can be used to implement the proposed generic framework for managing an authorised domain. The four novel solutions all involve secure means for creating, managing and using a secure domain, which consists of all devices owned by a single owner. The schemes allow secure content sharing between devices in a domain, and prevent the illegal copying of content to devices outside the domain. In addition, each solution incorporates a method for binding a domain to a single owner, ensuring that only a single consumer owns and manages a domain. This enables binding of content licences to a single owner, thereby limiting illicit content proliferation. In the first solution, domain owners are authenticated using two-factor authentication, which involves 'something the domain owner has', Le. a master control device that controls and manages consumers domains, and binds devices joining a domain to itself, and 'something the domain owner is or knows', i.e. a biometric or password/PIN authentication mechanism that is implemented by the master control device. In the second solution, domain owners are authenticated using their payment cards, building on existing electronic payment systems by ensuring that the name and the date of birth of a domain creator are the same for all devices joining a domain. In addition, this solution helps to protect consumers' privacy; unlike in existing electronic payment systems, payment card details are not exposed to third parties. The third solution involves the use of a domain-specific mobile phone and the mobil~ phone network operator to authenticate a domain owner before devices can join a domain. The fourth solution involves the use of location-based services, ensuring that devices joining a consumer domain are located in physical proximity to the addresses registered for this domain. This restricts domain membership to devices in predefined geographical locations, helping to ensure that a single consumer owns and manages each domain.
