"A voice identification system used by the Australian government for millions
of people has a serious security flaw, a
Guardian Australia investigation has
found.
Centrelink and the Australian Taxation Office (ATO) both give people the option
of using a “voiceprint”, along with other information, to verify their identity
over the phone, allowing them to then access sensitive information from their
accounts.
But following reports that an AI-generated voice trained to sound like a
specific person could be used to access phone-banking services overseas,
Guardian Australia has confirmed that the voiceprint system can also be
fooled by an AI-generated voice.
Using just four minutes of audio, a Guardian Australia journalist was able to
generate a clone of their own voice and was then able to use this, combined
with their customer reference number, to gain access to their own Centrelink
self-service account.
The voiceprint service, described as the “digital representation of the sound,
rhythm, physical characteristics and patterns of your voice”, was used by 3.8
million Centrelink clients as of the end of February, and more than 7.1 million
people had verified their voice with the ATO."
