Context Electronic Medical Records (EMR) is an integrative project with three main goals: Build a credible testbed for EMR research – Contribute to solving privacy and security challenges of – EMR systems applications Use EMR application testbeds for the integration , testing , – and evaluation of new technologies on core TRUST research areas, including: Model-based design for security and privacy o Formal modeling , verification, enforcement of privacy & o security policies Data mining & representation of real clinical workflows o Security & privacy technologies for sensor networks o Public policy to technology interactions o 2
Summary Experimental platform for Model-Integrated Clinical 1. Information Systems (MICIS) – Provide a common integration testbed for security and privacy aware Clinical Information Systems (CIS). Component integration platform 2. – Based on a standard Service-Oriented Architecture framework (SOA) – Extended Prolog-based Policy Evaluation Point & Policy Enforcement Point components (MICIS-PROPER) Reusable Platform-Independent – Integrated with the Apache Orchestration Director Engine (ODE)
Summary Model integration platform 3. – Built on Vanderbilt's metaprogrammable Model-Integrated Computing (MIC) tool suite – System models capture environment Workflows Organizations Services Roles Deployment Access control policies Messages Security policies Message Attributes – Privacy modeling language based on Stanford's work on contextual integrity Enables formal representation of permitted communications Considers past, as well as future, communication instances
Summary Model integration platform 3. – Experimental platform has several components: Set of domain-specific modeling languages – Captures relevant architectural components – Captures policy modeling aspects of selected CIS applications Model transformations – Map domain-specific models on the MICIS component integration platform Example application models Running experiments for analytic analysis
