The news is plentiful with descriptions of healthcare data breaches and ransomware. Among all of this gloom, there is another BoogeyMan being overlooked– the fact that hackers could potentially change your healthcare data. The motivations for doing this are anyone’s guess–but those that do these things channel George Mallory with a ‘because it’s there’ attitude. In reading about this a bit, it is interesting that little Estonia has invested in a presumably hack-proof digital health data infrastructure using block chain technology. It goes to show that it’s always worth looking to outside examples to be inspired to fix healthcare. But I do wonder– if someone hacked health data as to change it in a production system, do the QA and analytics processes exist capable to detect such changes? Do they in your organization?
