R&D Management challenges for the desing and development of an E2E-DRM content business integration platform

Current studies on Digital Rights Management (DRM) have focused on controlling access to and copies of contents, centered exclusively on the end of the value chain (end users). This focus has been oriented towards security and encryption as a means of solving the issue of illegal copying by purchasers. In this paper, we propose End-toEnd Digital Rights Management (E2E DRM) that involves the protection of the content throughout the entire value 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 value 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. The research was financed by the Autonomous Region of Madrid through the program “Aid to Promote Technological Innovation in the ICT sector

Rights and services interoperability for multimedia content management

The main goal of the work presented in this thesis is to describe the definition of interoperability mechanisms between rights expression languages and policy languages. Starting from languages interoperability, the intention is to go a step further and define how services for multimedia content management can interoperate by means of service-oriented generic and standardised architectures. In order to achieve this goal, several standards and existing initiatives will be analysed and taken into account. Regarding rights expression languages and policy languages, standards like MPEG-21 Rights Expression Language (REL), Open Digital Rights Language (ODRL) and eXtensible Access Control Markup Language (XACML) are considered. Regarding services for content management, the Multimedia Information Protection And Management System (MIPAMS), a standards-based implemented architecture, and the Multimedia Service Platform Technologies (MSPT), also known as MPEG-M standard, are considered. The contribution of this thesis is divided into two parts, one devoted to languages interoperability and the other one devoted to services interoperability, both addressed to multimedia content management. They are briefly described next. The first part of the contribution describes how MPEG-21 REL, ODRL and XACML can interoperate, defining the mapping mechanisms to translate expressions from language to language. The mappings provided have different levels of granularity, starting from a mapping based on a programmatic approach coming from high-level modelling diagrams done using Unified Modelling Language (UML) and Entity-Relationship (ER). The next level of mappings includes specific mappings between MPEG-21 REL and XACML and ODRL and XACML. Finally, a more general solution is proposed by using a broker. Part of this work was done in the context of the VISNET-II Network of Excellence and the AXMEDIS Integrated Project. The findings done prove the validity of the interoperability methods described. The second part of the contribution describes how to describe standards based building blocks to provide interoperable services for multimedia content management. This definition is based on the analysis of existing content management use cases, from the ones involving less security over multimedia content managed to the ones providing full-featured digital rights management (DRM) (including access control and ciphering techniques) to support secure content management. In this section it is also presented the work done in the research projects AXMEDIS, Musiteca and Culturalive. It is also shown the standardisation work done for MPEG-M, particularly on elementary services and service aggregation. To demonstrate the usage of both technologies a mobile application integrating both MPEG-M and MIPAMS is presented. Furthermore, some conclusions and future work is presented in the corresponding section, together with the refereed publications, which are briefly described in the document. In summary, the work presented can follow different research lines. On the one hand, further study on rights expression languages and policy languages is required as new versions of them have recently appeared. It is worth noting the standardisation of a contract expression language, MPEG-21 CEL, which has also to be further analysed in order to evaluate its interoperability with rights and policy languages. On the other hand, standard initiatives must be followed in order to complete the map of SB3's, considering MPEG standards and also other standards not only related to multimedia but also other application scenarios, like e-health or e-government

Scenarios and operator business models for management of digital homes

Digitaalisen kodin käsite on levinnyt nopeasti kuluttajien päivittäessä kotien laitteistoja digitaaliselle aikakaudelle. Digitaalisen kodin tunnusmerkkejä ovat kasvava verkkokykyisten laitteiden määrä ja niiden liittäminen sekä toisiinsa että Internetiin. Digitaaliset kodit muuttuvat koko ajan monimutkaisemmiksi ja niiden hallinta yhä haastavammaksi. Tämä työ pureutuu syntyvään hallintaongelmaan. Oletuksena on, että yritysten tarjoamat digitaalisten kotien hallintapalvelut ovat tulevaisuudessa keskeisessä asemassa kotikäyttäjiin suuntautuvassa palveluliiketoiminnassa. Tämä tutkimus esittelee neljä hallintaskenaariota, jotka kehitettiin asiantuntijahaastatteluista ja kirjallisuuslähteistä kerättyjen ideoiden ja tiedon avulla. Skenaariot tarjoavat näkemyksiä mahdollisista tulevaisuuden kehityssuunnista, ja selittävät hallintapalveluiden asemaa muuhun palveluliiketoimintaan nähden. Skenaariot on rakennettu tarkastellen toimialaa operaattorin näkökulmasta käsin. Esimerkit operaattorien liiketoimintamalleista ovat olennainen osa tämä tutkimusta. Ne yhdessä skenaarioiden kanssa osoittavat, että eri palveluiden yhdistäminen kokonaisuuksiksi (kytkykauppa) tulee olemaan tärkeä menestyksen aines. Kuluttajat eivät ole valmiita maksamaan digitaalisen kodin hallinnasta yksinään, vaan hallintapalveluiden kustannukset tulee peittää suurempien palvelukokonaisuuksien sisälle.The digital home is a new concept that has spread rapidly while consumers have been upgrading their electronic devices into the digital age. The increasing number of network-enabled devices, and connecting them with each other and to the Internet are the key characteristics of digital homes. This thesis attacks the problem that arises from the increasing complexity of managing the digital home systems. Management help offered by service providers to home users is assumed to play an important role in the future of digital home service business. With the help of ideas and information gathered from expert interviews and various written sources, four management scenarios were developed in this thesis. The scenarios provide insight into possible directions for future development, and explain the role of management provision in relation to the other domains of digital service business. The scenarios are constructed from the operator point-of-view. This thesis also presents examples of operator business models that together with the scenarios show that effective service aggregation will be an important success factor. The consumers will not be willing to pay for management as such; the cost of management should be hidden within a service bundle
