Solution Overview

Problem

Current authentication methods for callers in financial institutions are inadequate as they rely on easily accessible information, leading to potential unauthorized access and increased operational costs due to the need for repetitive questioning.

Innovation Solution

A system that uses voice recognition to authenticate callers by obtaining and comparing voice prints, calculating initial scores and confidence intervals to determine authentication, thereby reducing reliance on easily compromised information and streamlining the authentication process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional authentication methods asking identifying information are used, then authentication can be performed, but the information is easily accessible and can be compromised by fraudulent callers

Engineering Contradiction:
Improveauthentication securityVSAvoidinformation compromise
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces traditional mechanical/question-based authentication with acoustic/voice-based authentication. The system captures voiceprints of callers and compares them against stored voice profiles to authenticate identity, substituting the mechanical process of answering questions with acoustic pattern recognition that is much harder to replicate fraudulently.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If multiple identifying questions are asked to enhance security, then authentication accuracy improves, but call center operational costs increase due to time consumption

Engineering Contradiction:
Improveauthentication accuracyVSAvoidcall center efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The voiceprint authentication system performs self-service authentication automatically without requiring manual intervention from call center operators. The system independently captures, processes, and verifies voiceprints, freeing operators from repetitive authentication tasks and improving overall call center productivity while maintaining high authentication accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical process of operators asking and listening to answers with automated acoustic pattern recognition. The system automatically captures voiceprints, compares them against stored profiles, and makes authentication decisions without human intervention, significantly reducing the time operators would spend on each authentication interaction.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If voice recognition is used for authentication, then security is enhanced and repetitive questioning is reduced, but the system complexity increases

Engineering Contradiction:
Improveauthentication securityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a universal voiceprint authentication system that can be applied across multiple authentication scenarios and customer interactions. The same voice capture and comparison mechanism serves various authentication needs (account access, transaction verification, customer service authentication), making the system versatile and justifying the added complexity through multi-functional utility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Systems and methods for authenticating callers are disclosed that may obtain identifying data and a voice print, and compare the voice print to one or more stored voice prints. Further, one or more initial scores may be calculated based on the data and the comparison, and a confidence interval score may also be calculated. The systems and methods may determine whether to authenticate based on the one or more initial scores and the confidence interval score.
