    Introduction to the problem
    Virtual Data Centres
    Proposed solution
    Confidentiality in Virtual Data Centres  |  Christine O’Keefe
    Population Health Research Network*
    Provides access to linkable de-identified health data for research
     Improving outcomes
     Improving policy
    Traditionally
     Supplies linkable de-identified health data directly to researchers
    Loss of control over data heightens risk of:
     External attack on datasets
     Accidental or inadvertent actions by researcher
     Deliberate attack by trusted researcher
                                                                *www.phrn.org.au

    Secure Unified Research Environment*
    Secure remote access to virtual workstations and network in a data 
    centre

    Confidentiality Protection for Health Data 
    Governance
     Comply with privacy legislation and regulation
     Honour assurances to data providers
    Restrict access to approved researchers
     Information security measures
    Restrict amount and detail of data available
     Apply statistical disclosure control methods before releasing data to researcher
       – No further confidentiality measures
     Enable access via secure on-line system
       – Manual checking for confidentiality issues in statistical analysis outputs
       – “…developing valid output checking processes that are automated is an open 
         research question” (Duncan, Elliot, Salazar-González 2012)

    Conceptual Model for online access
                VDC
                                                                          RA
    Remote Analysis
     Researcher cannot see data itself, only “Output for publication”
    Virtual Data Centre
     Researcher authorised to see data and “Output” as well as “Output for 
       publication”
