AUTHENTICATION VIA A DYNAMIC PASSPHRASE
First Claim
1. A computer-implemented method for voice authentication of a customer in a self-service system, the computer implemented method comprising:
- receiving a request for authentication of the customer, the customer is enrolled in the self-service system with a text-independent voice print;
determining a passphrase from a plurality of passphrases to transmit to the customer based on comparing each of the plurality of passphrases to a text-dependent or text-independent voice biometric model;
transmitting a request to the customer to repeat the passphrase;
receiving an audio stream of the passphrase;
authenticating the customer by comparing the audio stream of the passphrase against the text-independent voice print; and
if the customer is authenticated, then storing the audio stream of the passphrase and the topic of the passphrase.

Abstract
A computerize method for voice authentication of a customer in a self-service system is provided. A request for authentication of the customer is received and the customer is enrolled in the self-service system with a text-independent voice print. A passphrase from a plurality of passphrases to transmit to the customer is determined based on comparing each of the plurality of passphrases to a text-dependent or text-independent voice biometric model. The passphrase is transmitted to the customer, and when the customer responds, an audio stream of the passphrase is received. The customer is authenticated by comparing the audio stream of the passphrase against the text-independent voice print. If the customer is authenticated, then storing the audio stream of the passphrase and the topic of the passphrase
