It's hoped the COVID-19 contact tracing app will be rolled out later this month.
The app, which has been in development since March, is due to go to Government for approval beforehand.
It's currently being trialed by Gardaí, as they are one of the few groups permitted to move freely around the country.
HSE CEO Paul Reid outlines the data protection measures that have been put in place.
"The data is not held on the central health systems, it is in some countries.
"In ours it'll be held on the person's phone, and distributed out through the app so the data is not held centrally and cannot be used centrally.
"That's the communications that we'll be putting in as we go to launch the app."
