Yesterday an ABC investigation revealed that data given to the app Health Engine, which allows you to book GP appointments, is allegedly giving patient data to third parties without express consent.

This has caused concern from users, who are unsure who could have their data, or what kind of data they may have unwittingly handed over.

It has also caused people to think about the upcoming My Health Record system run by the Federal Government, and whether their data will be secure on a government system.

Brian Carlton has often talked of his concerns over My Health Record. He speaks with Chair of the Health Committee of the Australian Privacy Foundation, Dr Brendan Robertson-Dunn, about the systems, and why we should be wary of them.
