The Industrial Bank of Korea (IBK) first launched its voice biometrics authentication of its customers in June 2020. Now, IBK will be utilizing Nuance Communications technology to create what is claimed to be the banking industry’s first biometrics solution for video calls, Nuance announced this week.

Nuance’s solution, Nuance Gatekeeper, is a cloud‑native, decision‑making, AI‑powered biometric solution for frictionless authentication, according to the company website. The Gatekeeper analyzes customer voices for more than a thousand characteristics, which includes both physical traits and behavioral characteristics, such as rhythm, intonation, and pace.

IBK will incorporate the technology during both video and phone conversations to leverage biometrics for voice authentication during video calls. This comes in response to the increase in fraudulent attacks infiltrating customer accounts during the pandemic.

With Gatekeeper, IBK customers can securely communicate with customer support via phone and video chats without the fear of fraudulent behavior or voice replication. Nuance already protects 600 million consumers worldwide, its customers report that the volume of fraud attacks has risen 200-400 percent.

“With Nuance Gatekeeper, we’ve made it easier and more secure than ever for customers to bank by phone or video without having to visit our branches.” said Shinwoo Kang, Customer service strategy manager at IBK.

IBK has already enrolled more than 100,000 customers for voice biometric authentication, according to the announcement.
