AI Fools Voice Recognition Used To Verify Identity By Australian Tax Office

A voiceprint program used by millions of Australians to access data held by government agencies can be fooled by an AI-generated voice, reports the Guardian. From the report: 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. 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. Anyone trying to use voiceprint also needs to know the account-holder's customer reference number, which is not normally publicly available, but the number is not treated as securely as a password and is included in correspondence from Centrelink and other service providers, such as childcare centers. The self-service phone system allows people to access sensitive material such as information on their payment of benefits and to request documents to be sent by mail, including replacement concession or healthcare cards. Services Australia declined to say if the voiceprint technology would be changed or removed from Centrelink.
