Issues in security for Digital Rights Management

Panel objective

Security and Digital Rights Management (DRM) are key topics in many contexts. However, when we put both together and we try to specify an architecture for them, we confront new research issues that are based on current ones. This is the focus of this Panel.

In particular, the topics to be discussed include:

  • Architectures to manage digital rights for audiovisual content considering its whole life cycle, from its creation to its consumption by end users.
  • Definition of mechanisms for the secure management of licenses.
  • Definition of key storage and distribution architectures considering web services, secure storage for the secure management of keys, authentication, certificates, etc.
  • Event Reporting security.
  • Security mechanisms compatible with content adaptation.
  • Access control frameworks and their integration in broader architectures and applications.
  • Architectures for Access Control and DRM interoperability.
  • Interoperability of the representation information for DRM (licenses) and SAML (security) and other possible standards.
  • Use of Semantic Web tools to formalise semantics for security services.
  • Use of Ontologies for policy management.
  • DRM and Security solutions: Benefits to publishers.

The VISNET-II (Networked Audiovisual Media Technologies) Network of Excellence co-funded by the European Commission is working, in one of its workpackages, on the topics mentioned above. Results will be presented in order to start discussions with the aim of identifying research issues and services and products to develop.

Furthermore, other projects, as OpenSDRM, from ADETTI, or CENIT Segur@, co-funded by the Spanish Ministry of Industry, will also present their approach to the issues.

The OpenSDRM project has its roots on former MOSES EC RTD project, where a open DRM platform had to be build to support the emerging MPEG-4 IPMP eXtensions framework. OpenSDRM is an open-source, secure and distributed DRM architecture to support the complete digital content value chain, from content provider to the end-user. OpenSDRM source-code is publicly available and can be used to test and establish DRM governed digital content scenarios.

The Segur@ project has started working in architectures for the development of semantic trust and for the development of trust based on data. Then, in this project, ontologies for basic security services will be defined and how ontologies can help in policy management will be analysed.

Panel questions

Some of the questions that will be discussed in the panel are:

  • Are there pending security issues in existing DRM systems?
  • How security can help to the management and distribution of licenses and keys?
  • Can security (or access control) and DRM architectures interoperate?
  • How they interoperate in specific environments, such as Virtual Collaboration?
  • Can intellectual property rights information be adequately represented and processed using SAML, XACML or other standards?
  • How semantic web tools can be used to formalise basic security services?
  • How ontologies can help to the specification and management of policies?
  • How DRM supports publishing business models?
  • Are publishers taking benefit from existing DRM and Security solutions?
  • Is open-source DRM a solution for DRM?
  • How the DRM market will shape for the future?
  • DRM - rights management vs. copy-protection?
