Replacing KBA with Voice Biometrics for 8 Million Customers

The Challenge

An Indian bank's knowledge-based authentication (KBA) was failing — fraud losses from KBA bypass were rising, and average authentication time of 90 seconds was driving customer abandonment.

The Solution

ALPANDIA's voice biometrics enrolled 8 million customers using existing call recordings, then authenticated callers in under 3 seconds using voice prints — eliminating KBA entirely for enrolled customers.
