Should You Put Your Trust in Voice Authentication Technology?


When it comes to digital security, we're in the midst of a transition. We're essentially advancing from passwords and security questions to biometrics, which in turn can take the form of facial recognition, fingerprint ID, or voice authentication. By and large, these options offer greater convenience, quicker access, and in many respects, better security.

But if you're running a business with digital security needs, should you put your trust in voice authentication tech? Here are a few factors to consider in answering that question.


Preserved Privacy

Arguably the central question about biometrics security has been whether or not it can preserve privacy. It's a fair question, but one that applies primarily to fingerprint scans and facial recognition. As our article on voice biometrics and security points out, there is more privacy where the voice is concerned. That article noted "substantiated concerns about facial biometrics" and fingerprints regarding profiling, misidentification, and facial and fingerprint data storage. By contrast, "the part of speech that is collected to authenticate a person" is also saved — but only in a file that is useless on its own.


This doesn't mean that privacy violations or vulnerabilities are entirely impossible. Still, it's clear that voice authentication preserves privacy far more effectively than other biometrics, which is one reason to trust it with your business.


Ongoing Improvement

Another reason to trust in voice authentication is that it's bound to become more reliable and secure in time. This is because of the expected growth and improvement in the field of cybersecurity in the next several years. Alongside voice authentication and other emerging technologies, there is a rapidly growing demand for cybersecurity skills in virtually every essential industry. The need for workers in the field almost doubled from 2013 to 2019 — and growth moving forward is looking even better. This means that we will inevitably be seeing new solutions and more sophisticated digital security protocols for the foreseeable future. And these improvements will include refining any safety or security concerns that arise around specific voice authentication applications.


Another significant contributor to the ongoing improvement of voice authentication and any voice technology is the rapid advancement of data science and data science education movement. Making data science education more accessible through in-person and online degrees has led to a growing number of students pursuing advanced degrees in this field. As more data science experts emerge in the future, we can look forward to data science advancement, which is the key to the evolution of voice authentication technology. Those who undertake an online master's in business data analytics are being trained in key database principles, advanced analytics, data modeling, and other key skills in this highly specialized field. And as more data science experts emerge in the future, we can look forward to the advancement of data science, which is the key to speech recognition and the evolution of other voice technologies.


Voiceprint Exploitation

Despite the security benefits mentioned above, there are some concerns about voiceprint identification. A voice if more unique and identifiable as a fingerprint when analyzed by the right technology. And it's a given that cybercriminals, with interest in exploiting biometrics, are working to make use of that technology and find ways to seize and make use of voiceprints.


This doesn't mean that voice authentication is untrustworthy — only that it has some potential vulnerabilities. The good news is that when used for identification or password purposes, authentication systems pay attention to what is said, rather than just who's saying it. For this reason, even a hacked voiceprint — which is still very uncommon and unlikely — isn't necessarily enough to constitute a breach of an authentication system.


Altogether, voice authentication offers promising and advanced biometrics solutions that are likely to become more and more normal moving forward. And many of the world's largest industries and enterprises are increasingly learning to trust and leverage this emerging biometric technology.
