There is a strict oversight process in place within the HSE for both; a) the data being used in the course of producing reports and b) the ICT systems being deployed to process the data used and produce the reports.
The ICT system used to produce consolidated reports to inform Government in its management of the COVID-19 response is a separate instance of the HSE’s business analytics system, which allows for the isolation of this work from the rest of the HSE’s data systems and databases.
The information processing and report production process limits its use of data to aggregated and anonymised/pseudonymised data and not citizen level data.
