Cybercriminals Can Break Voice Authentication With 99% Success Rate
HelpNet Security, Thursday, July 6,2023
Computer scientists at the University of Waterloo have discovered a method of attack that can successfully bypass voice authentication security systems with up to a 99% success rate after only six tries.
Voice authentication - which allows companies to verify the identity of their clients via a supposedly unique 'voiceprint' - has increasingly been used in remote banking, call centers and other security-critical scenarios.
'When enrolling in voice authentication, you are asked to repeat a certain phrase in your own voice. The system then extracts a unique vocal signature (voiceprint) from this provided phrase and stores it on a server,' said Andre Kassis, a Computer Security and Privacy PhD candidate and the lead author of a study detailing the research.
