Emergency Telecom Voice Verification to Replace PIN Authentication

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing emergency telecommunications services, such as the Government Emergency Telecommunications Service (GETS), face inefficiencies and security vulnerabilities due to manual entry of PINs, which increase call setup time, complexity, and susceptibility to errors and misuse, leading to potential loss of prioritized network access during emergencies.

Innovation Solution

Implementing voice verification using voice biometrics for authentication, allowing users to enroll in a voice verification system, where a voice passphrase is used instead of a PIN for secure, multi-factor authentication, reducing call setup time and complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual PIN entry is used for authentication, then security is provided, but call setup time increases and complexity increases

Engineering Contradiction:

ImprovesecurityVSAvoidcall setup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical manual PIN entry system with an automated voice biometric authentication system. The voice recognition system automatically captures, processes, and verifies user identity through voice patterns, eliminating the need for manual keypad entry and reducing call setup time while maintaining security through biometric verification.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The voice biometric system enables self-service authentication where the user's own voice characteristics serve as the authentication credential. The system automatically extracts voice features, compares them against stored biometric data, and completes authentication without requiring manual intervention or complex user actions, thereby reducing both time and complexity.

Inventive Principle:

Principle #25Self-service

2Reliability

If manual PIN entry is used for authentication, then security is provided, but device complexity increases

Engineering Contradiction:

ImprovesecurityVSAvoidauthentication complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent substitutes the complex manual PIN entry process with an automated voice biometric system that handles authentication through automated voice capture, feature extraction, and pattern recognition. This reduces the operational complexity for users while maintaining robust security through sophisticated biometric verification algorithms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system utilizes the user's inherent voice characteristics as a self-contained authentication mechanism, eliminating the need for users to remember or manually enter complex PINs. The voice biometric system automatically performs all authentication steps, simplifying the user experience while maintaining security through unique biological trait verification.

Inventive Principle:

Principle #25Self-service

3Reliability

If manual PIN entry is used for authentication, then authentication is achieved, but susceptibility to errors increases

Engineering Contradiction:

Improveauthentication accuracyVSAvoiderror susceptibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces error-prone manual PIN entry with automated voice biometric authentication that captures voice patterns directly. This eliminates human errors such as incorrect digit entry, forgetting PINs, or misalignment with automated voice systems, thereby improving authentication accuracy and ease of operation through automated biometric verification.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The voice biometric system leverages the user's own voice as a unique, error-resistant authentication credential. Since voice patterns are inherently unique and difficult to replicate or mistake, this self-service approach minimizes authentication errors while simplifying the user experience through natural voice-based verification.

Inventive Principle:

Principle #25Self-service

AI summary

A method comprises receiving a first call from a user device operated by an emergency personnel, receiving a personal identification number associated with the emergency personnel from the user device, validating the personal identification number by verifying that the personal identification number is stored at a data store in association with an active account, wherein the active account is associated with the emergency personnel, transmitting a first prompt for voice verification registration to the user device, receiving a response from the user device to perform the voice verification registration in response to the first prompt, and either performing voice verification with the user using the user device or transmitting a prompt for a requested destination to the user device based on the response.
