Voice authentication systems are gaining momentum as a reliable method for verifying an individual's identity. However, a recent study conducted by computer scientists at the University of Waterloo has shed light on the potential vulnerabilities of these systems. Shockingly, these systems can be compromised with a success rate of up to 99% within six attempts, according to the study. In this article, we delve into the details of the study and its implications for the future of voice authentication.

Voice authentication, also known as "voice auth", is a biometric security measure that uses a person’s unique vocal characteristics, such as pitch, tone, and accent, to verify their identity. The system creates a voice print by analyzing these traits, which is then compared to a saved print to confirm if the user is genuine. Andre Kassis, a Computer Security and Privacy PhD student and the lead author of the study, explains the process:
“When enrolling in voice auth., you are asked to repeat a certain phrase in your own voice. The system then extracts a unique vocal signature (voiceprint) from this provided phrase and stores it on a server … For future auth. attempts, you are asked to repeat a different phrase and the features extracted from it are compared to the voice print you have saved in the system to determine whether access should be granted.”

Details of the Study
The study, spearheaded by computer scientists at the University of Waterloo, developed a method that circumvents spoofing countermeasures, potentially fooling most voice auth. systems within six attempts. This method involves creating adversarial audio samples designed to deceive the voice auth. system.
Unlocking the Secrets: Seamless Data Transference from Your Old Smartphone to the New OneUpon testing their method on 18 commercial voice auth. systems, including those used by banks, credit card brands, and voice assistants, the researchers discovered that they could bypass all of them with a success rate of up to 99% within six tries. Even the Amazon Connet voice auth. system was not spared, with a 10% success rate in a 4 seconds attack which rose to 40% in less than 30 seconds and touched 99% after six attempts.
Implications for Voice Authentication
The findings of the study have profound implications for the future of voice auth. The study highlights that voice auth. systems are susceptible to attacks and may not be as secure as previously thought. The researchers proposed that voice auth. systems should adopt more robust anti-spoofing measures to prevent the creation of adversarial audio samples.

Pindrop's Similar Findings
The researchers at the University of Waterloo aren't the only ones who have conducted such research. A team at Pindrop, an IT security company specializing in voice auth. and security, carried out a similar study, and the results align closely with the claims made above. While the University of Waterloo focused on bypassing the voice auth. system itself, Pindrop's study examined the weakness of knowledge-based authentication questions used by voice auth. systems.

The findings of these studies highlight the risks of voice auth. Fraudsters are becoming increasingly sophisticated, exploiting weaknesses in contact centres and IVRs using data breaches, smishing attacks, and generative AI. Despite these risks, voice auth. remains an easy and secure way to verify a person’s identity, more secure than traditional authentication methods like passwords and PINs, which can be easily compromised or stolen.
Best Practices for Voice Authentication
Given the potential security threats, it's essential to follow best practices to ensure the safety of voice auth. systems. Some of these practices include:
- Combining call metadata, device and behaviour analysis, and risk intelligence for secure caller authentication without their voice.
- Using number validation to simplify the authentication process and reduce fraud risk.
- Requiring secure passwords and authentication.
- Applying sound security practices when developing new products.
- Storing sensitive personal information securely and protecting it during transmission.
- Including appropriate security standards in your contracts.
Concluding Thoughts
As voice auth. continues to become prevalent, it's crucial to ensure these systems are secure and reliable. The convenience and security of verifying a person’s identity through voice auth. cannot overshadow the risks it poses. Fraudsters are becoming increasingly sophisticated, using data breaches, smishing attacks, and generative AI to exploit vulnerabilities. Therefore, following best practices and staying ahead of fraudsters is essential. Stay safe!
