Outline • Need …. • Things to be Considered • NHIS Pathways • Current Work 2

Need …… National Health Information System (NHIS) “the transparent and secure access to health information across geographically distributed healthcare centers” Objective: for better national public health policy - healing and controlling diseases - promoting good health - health personnel - efficient use of budget 3

Things to be Considered Diversity: health information structures among healthcare centers • (approximately 30 different data structures) Availability: information sharing from healthcare centers • Accessibility: efficient information access to at least 10,000 • healthcare centers Privacy and privilege of heath information • 4

NHIS Pathway • Phase I : Information Transformation – Objective • to enable the interoperability & usability of health information across healthcare centers – Goal • National Health Metadata Standard • Metadata Mapping Tool (MMT) • Metadata Conversion Tool (MCT) – Technology • XML • Rich Interface Application 5

6

NHIS Pathway • Phase II: Information Sharing & Interoperability – Objective • to make health information sharing possible • to provide an efficient information access to a large number of healthcare centers – Goal • Metadata Service (MS) • Metadata Broker (MB) – Technology • Web Services, XML, P2P 7

NHIS Pathway • Phase III: Information Security – Objective • to promote the privacy and privilege of health information w.r.t. consumers’ roles – Goal • Authorization Service (AS) - verifies user credentials and generates data access policy • Extended Metadata Service (MS) - handles information security issues • Extended Metadata Broker (MB) - handles information security issues – Technology • Public Key Infrastructure (PKI) • Privilege Management Infrastructure (PMI): Role-based Access Control (RBAC) • Web Service Security Standards 9
