Voice Authentication Server for Secure Identity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current identity verification methods, such as two-factor authentication and identity document checks, are burdensome and time-consuming, especially for bank account openings and password resets, often requiring physical presence and multiple steps, which can be inconvenient and insecure.
Innovation Solution
A method and system for secure voice authentication using a voiceprint, where users can authenticate through voice recognition, leveraging an existing telecommunications provider's database for identity verification, allowing voice-based two-factor authentication for online services, eliminating the need for physical presence and reducing the complexity of traditional verification processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional two-factor authentication and identity document checks are used, then security is improved, but user convenience and time efficiency deteriorate
Solution Approach 1:
The patent replaces physical document verification and mechanical authentication processes with voice-based biometric authentication. The voiceprint analysis system substitutes the need for physical presence at post offices or branch offices, allowing users to authenticate remotely through voice commands while maintaining security through biometric verification.
Solution Approach 2:
The patent introduces a voiceprint database and automated voice analysis system as an intermediary between the user and the authentication service. This intermediary processes voice recordings, compares them against stored voiceprints, and automatically verifies identity without requiring human operators to manually check documents or perform authentication steps.
2Reliability
If physical presence and document verification are required, then authentication reliability is improved, but time consumption and process complexity increase
Solution Approach 1:
The patent performs preliminary voiceprint capture and storage during the initial account setup or identity registration phase. Once the voiceprint is enrolled in the database, subsequent authentication processes can quickly compare new voice inputs against the pre-stored reference without requiring time-consuming document verification or physical presence, thus reducing time consumption while maintaining reliability.
3Reliability
If multiple authentication factors are required, then security is improved, but device complexity and operational burden increase
Solution Approach 1:
The patent creates a universal voiceprint-based authentication system that can serve multiple authentication factors (something the user is) across different services and contexts. The same voiceprint database and analysis methodology can be applied whether authenticating for bank account opening, password reset, or transaction verification, simplifying the overall system architecture while providing multi-factor authentication capabilities.

AI summary
For improving and/or simplifying the verification of a person's identity, as it is for instance required for opening a bank account, the invention proposes a method for multi-factor authentication, said multi-factor authentication comprising a voice based authentication, the method comprising the steps of a) capturing a voice input provided by a user, b) transmitting an authentication request from an authentication requesting device to an authentication server (300), wherein said authentication request comprises the captured voice input, c) verifying the user's identity by the authentication server (300) based on the received voice input and generating an authentication response by the authentication server (300) depending on the result of the verification, and d) transmitting the authentication response from the authentication server (300) to a predefined response receiving device. The invention further proposes an authentication server and an authentication system, which are adapted to perform the method.
