Voiceprint Authentication via Automated Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems that rely on PINs for authentication fail to uniquely identify users, leading to unauthorized transactions and increased risk of fraud, especially in electronic and remote transactions.
Innovation Solution
A biometric authentication system using voiceprints is implemented, where users register and authenticate through voice data captured during automated calls, comparing the captured voiceprints with stored registered voiceprints to authorize secure transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a PIN-based authentication system is used, then the system is simple to operate and implement, but the system cannot uniquely identify users and is vulnerable to unauthorized access
Solution Approach 1:
The patent replaces the mechanical PIN entry system with an acoustic voiceprint recognition system. The voice-based authentication captures unique vocal characteristics through automated calls and compares them against stored voiceprints, providing biometric-level security without requiring complex hardware changes at the user end.
Solution Approach 2:
The system introduces an automated calling system as an intermediary between the user and the authentication process. This intermediary captures voice data during a natural phone conversation, eliminating the need for users to directly interact with complex authentication hardware while ensuring secure verification through voiceprint comparison.
2Reliability
If voiceprint authentication is implemented, then user identification reliability is improved, but the system complexity and implementation cost increase
Solution Approach 1:
The voiceprint authentication system operates autonomously through automated calling sequences that independently capture, process, and verify voice data without requiring manual intervention from authentication specialists or complex user setup procedures. The system serves itself by automatically managing the entire verification process.
Solution Approach 2:
The automated calling system serves multiple functions: it acts as a communication channel, a voice data capture device, an authentication verifier, and a user identification tool. This multi-functionality eliminates the need for separate dedicated hardware for each function, reducing overall system complexity while maintaining high identification accuracy.

AI summary
The systems and methods described herein allow an electronic transaction to be performed upon determining, via biometric data, that an authorized individual is conducting the transaction. This may involve receiving, by a computer system, a request to authorize an electronic transaction for an account. The computer system is configured to access a phone number, which is stored in computer memory and associated with the enrolled user of the account. An automated and outward call to the phone number is performed by the computer system. The computer system is configured to capture a voiceprint in association with voice data received from the automated call. The captured voiceprint is compared to a registered voiceprint, which is stored in the computer memory in association with the enrolled user. The computer system responds to the request to authorize the secure electronic transaction based on said comparison.
