While it’s certainly possible to sometimes do biometrics well, a long line of companies frequently… don’t. Voice print authentication is particularly shaky, especially given the rise of inexpensive voice deepfake technology. But, much like the continued use of text-message two-factor authentication (which is increasingly shown to not be secure), it apparently doesn’t matter to a long list of companies.
Banks and telecom giants alike have started embracing voice authentication tech at significant scale despite the added threat to user privacy and security. And they’re increasingly collecting user “voice print” data without any way to opt out:
“despite multiple high-profile cases of scammers successfully stealing money by impersonating people via deepfake audio, big banks and ISPs are rolling out voice-based authentication at scale. The worst offender that I could find is Chase. There is no “opt in”. There doesn’t even appear to be a formal way to “opt out”! There is literally no way for me to call my bank without my voice being “fingerprinted” without my consent.”
