How Secure Are Voice Authentication Systems?

University of Waterloo (Canada) (06/27/23) via ACM TechNews

Computer scientists at Canada's University of Waterloo have developed an
attack that can bypass voice authentication security systems after six
attempts. They created a program able to remove the markers in deepfake
audio so it is indistinguishable from authentic audio. Although their
success rate against Amazon Connect's voice authentication system ranged
from just 10% in a four-second attack to more than 40% in an attack of less
than 30 seconds, their success …
