  1. DMAG contribution to the HL7 Security and Privacy Ontology Jaime Delgado, Eva Rodríguez, Víctor Rodríguez Distributed Multimedia Applications Group (DMAG) Universitat Politècnica de Catalunya (UPC) (Member of HL7 Spain)

  2. Contents • Objectives • DMAG • MVCO • HL7 Security and Privacy Ontology versus MVCO • Comments to the HL7 Security and Privacy Ontology • Future Work

  3. Objectives • Usage of the Media Value Chain Ontology (MVCO) to represent the HL7 Role Based Access Control (RBAC) • MVCO has been standardised by ISO/IEC JTC1/SC29 WG11 (MPEG) as ISO/IEC IS 21000-19 • Provide comments to the HL7 Security and Privacy Ontology (version for initial peer review) • Contribute to the use of Digital Rights Management (DRM) as an alternative to RBAC

  4. DMAG • Research group of the Computer Architecture Department at the Universitat Politècnica de Catalunya (UPC) in Barcelona (Spain) • Standardization Experience: Editors of several standards in working groups of ISO/IEC, EWOS, CEN/ISSS, ETSI and ITU-T • Experience in European Projects • Participation in the creation of Ontologies for different aspects of the content value chain, including user roles, rights and actions, domains, etc.

  5. MVCO • ISO/IEC IS 21000-19 standardizes a Media Value Chain Ontology (MVCO) that formalizes the representation of the Media Value Chain

  6. HL7 Security and Privacy Ontology versus MVCO HL7 RBAC Ontology Model MVCO Model equivalent to the HL7 Ontology

  7. Comments to the HL7 Security and Privacy Ontology • The Security and Privacy ontology might be split in two, since it includes elements for the security domain and elements for record objects together • The ontology file could be more self-descriptive • More individual examples might be added to the DemoLocalSecurityAndPrivacy Ontology, since having a good collection of individual examples is pivotal for understanding the model • The Functional Roles defined in the VeteransHealthAdministration ontology might be defined in the same way

  8. Comments to the HL7 Security and Privacy Ontology • Define in the VeteransHealthAdministration ontology how associations between Permissions and Roles should be defined for Roles to which not all the permissions are granted • Subclasses of Permissions (e.g. NewConsultOrder) should be defined as an individual of the Permission class. Example:

  9. Future Work • Tools • Usage of ISO “Reference Software” developed for the MVCO • DRM: • MPEG-21 Standard technologies as an alternative to RBAC • MPEG-21 alignment • Usage of the MPEG-21 Multimedia Value Chain Ontology (ISO/IEC 21000-19) to represent the HL7 RBAC
