“My voice is my password” and similar phrases have begun to be used for secure voice authentication for banks and health insurers and other critical services that require security and privacy.
It’s likely that several of your own service providers will roll this out in the next couple of years. Progress, right?
The problem is that in the short time since voice identification models have become mainstream and slick enough to be used in call centers, voice spoofing technology has exploded. It is now trivial to create voice tracks saying whatever you want them to say without human ears being able to tell any difference, and increasingly, fooling the voice authentication models too.
Worse, we are probably only a few years from trivial video spoofing with the same qualities.
I support the idea of moving away from passwords and improving security, but I struggle to understand how voice authentication is anything other than a tiny blip in the timeline before it becomes the easiest vector for fraud yet.
