The Nationwide Health Information Network (NHIN) requires the secure connection of health organizations within and across state borders. The goal of Phase 4 of the e-Authentication Pilot Study is to investigate a specific solution to this issue. In 2006 HIMSS sponsored Phase 1 of the e-Authentication Pilot Study which modeled the use of the General Services Administration (GSA) electronic authentication certificates using PKI and SAML in a healthcare information exchange (HIE) environment by 6 Regional Health Information Organizations (RHIOs) located in 5 different states. Phase 2 extended the work of Phase 1 to model federated single sign-on into a distributed multi-state HIE using PKI certificates for secure identity management, open source Internet2 middleware (Shibboleth and Shibboleth tools) for the authorization architecture and OASIS Security Assertion Markup Language (SAML) for single sign-on and access control. Phase 2 concluded in the development of a healthcare specific configuration of the Shibboleth network architecture and the development of healthcare related directory objects for role-based authorization. The Phase 2 technology was successfully demonstrated in the 2008 IHE Showcase. Phase 3 of the e-Authentication Pilot Study extended the network to include NHIN connectivity as a participant in the NHIN2 project. Advancements included; Record Location Services (RLS), proprietary Electronic Health Records (EHR), Personal Health Record Service (PHR), Public Health Immunization Record Service, VMWare virtual server technology. Phase 4 extends the use of NHIN Connector for Clinical and Administrative transactions, connection to OpenVISTA, work with the Voluntary Universal Healthcare Identifier (VUHID) and the growth of the network to 18 hospitals. Liberty Alliance/Kantara Workgroup for Health Identity and Assurance continues to participate to define Health Identity Management best practices and Role-based Authentication.
