Protecting health data privacy while using residence-based environment and demographic data.
Rodgers SE, Demmler JC, Dsilva R, Lyons RA.
Spatial analyses of environment and health data are often made using point address data, despite the risk of identity disclosure. Geospatial environment and non-spatial health data can be linked anonymously, thereby maintaining geoprivacy. Population density, housing and environment data may be anonymously linked to individual-level demographic data using a split file method and residential anonymous linking fields. This method has the potential to be used to evaluate natural experiments and complex environmental health interventions.
