Voice biometric identity verification is relatively new on the mainstream stage. So, we still have quite a bit of work to do in correcting misconceptions that are floating around about the technology.
Just recently, for instance, we were notified about a report from an anti-fraud firm claiming that error rates on voice biometrics could double over the next two years. According to the report, this is because human voiceprints change subtly in pitch and speed over the course of several months or years.
“Too many companies will just deploy voice biometrics, and that’s a mistake,” the report stated. “There’s a real need for multifactor authentication, with voice biometrics just being a piece of the puzzle.”
For this reason, the report explains, companies should use multifactor authentication in conjunction with voice biometric identity verification.
So, is there any truth to this? Here’s our take on the matter:
VoiceVault strongly supports multifactor authentication, but not for the reason mentioned in the report.
It’s true, voiceprints do change subtly over time. However, VoiceVault’s voice biometric platform was designed to constantly adjust to an end user’s voiceprint. Our voice biometric engine is always learning, and is therefore less susceptible to errors.
What’s more, voice readings are easily replaceable. If some sort of major incident happens that impacts an end user’s voice, like accident or injury, that person could simply re-enroll without a hassle.
As for multifactor authentication, we recommend it more for reasons related to security and convenience. Voice biometric authentication, for instance, is not optimal for every type of environment — like a crowded or noisy room. In this type of environment, users may have an easier time using a fingerprint scanner or even a traditional password. So it’s nice to offer end users a variety of login options.
What’s more, multifactor is a great way to enhance security. It’s possible to set up an account so that an end user has to use two or more authentication solutions before being granted access into a private account.
