title: Measures implemented to project personal privacy for an on-line national patient index: a case study.
abstract: Increasing use of electronic data storage and exchange is inevitable. Although of considerable benefit to all concerned, they pose a potential threat to personal privacy. Measures to protect personal privacy in national information networks are essential. These and related security issues require the highest priority in strategic planning because experience shows that poor handling of security is the single factor most likely to lead to rejection of a system. It is increasingly important to be able to identify individuals uniquely for health-related purposes, and implementation of an on-line master index is the approach that has been adopted in New Zealand to address this need. Such an index, however, contains personal information, the privacy of which must be respected. Substituting the unique identifier for all personal details in electronic messages can provide a degree of security as long as access to the index is controlled and usage is monitored. The article outlines the measures, technical and otherwise, implemented to manage security concerns successfully in that context.
