Secure Logic chief executive Santosh Devaraj told iTWire there were serious concerns about the security and privacy principles which the My Health Record platform relied upon, as hundreds of thousands of medical practitioners would have access to the data.
And this would be with "limited access controls, including underage patients. This creates potential entry points for hackers which are subject to little-to-no security oversight", he said.
Devaraj, who earlier this month called for the government to put in place laws to make Internet of Things devices safer, said the existing MHR system had no reliable mechanism that would guarantee confidentiality and privacy of data.
My Health Record has been dogged by controversy due to its default policy of opting everybody in.
Said Devaraj: “The problem is amplified by the rapidly increasing number of IoT devices being used in the health industry, and the whole new array of attacks still to be detected. With IoT still being a largely unregulated area, medical practitioners cannot assure the integrity of the data. Even when a compromise is detected, it won’t be possible to validate if the data is genuine, and separate it from tampered records. We need effective regulatory initiatives from government addressing regulation, law, and educational aspects on the issue.”
The MHR system has also faced a row over privacy recently and the government has had to back down and change the laws governing release of data.
Devaraj said the opt-out nature was "not compatible with the opt-in nature of the Record Access Code – an optional recipient-controlled PIN which would restrict unauthorised access".
"Without having this access code as the default, most users will inadvertently leave their records exposed in the event of a breach in a single access point. Subsequently, a security failure in just one doctor’s office could provide unfettered access to the sensitive information of millions of Australians," he said.
“The implications of a breach or misuse of medical information could be severe – medical institutions have become among the most prized targets for local and international cyber criminals because of the value this data has for blackmailers and on the dark web. We’ve seen this play out in the recent hack of Singapore’s SingHealth database.”
In the incident he cited, Singapore's government health database was breached by attackers who stole the personal information of about 1.5 million people, with the data of Prime Minister Lee Hsien Long specifically targeted.
“A blockchain-based platform could deliver on the dual goals of bringing healthcare into the digital age, while maintaining the security and privacy of Australians’ sensitive information," Devaraj said.
"However, under the current security regime, I would encourage Australians to opt out, and the government to extend the opt out period to ensure the public has made a properly informed choice about their participation."
Under pressure from the opposition Labor Party, the government has now extended the date for opting out to the end of January 2019.
“The introduction of tougher penalties for those who misuse the system is unlikely to provide a major deterrent to cyber criminals, particularly those based overseas and far away from the jurisdiction and reach of the Australian federal authorities," Devaraj said. "We need to be focused on preventive, rather than punitive, measures.”
