Solution Overview

Problem

Current user authentication methods, such as entering account numbers and passwords, are vulnerable to illegal access and misuse of personal information, posing significant safety concerns.

Innovation Solution

A method and apparatus for authenticating users using voiceprint authentication, where a user terminal receives an authentication request, determines if the user operation matches a preset operation, sends voicing material for reading, and authenticates the user based on the user identification and authentication voice, including voiceprint feature extraction and similarity calculations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional authentication methods (account number and password) are used, then the authentication process is simple and fast, but the security and reliability of user information is compromised

Engineering Contradiction:
Improveauthentication securityVSAvoidauthentication process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical authentication (keyboard input of passwords) with acoustic field-based authentication (voiceprint recognition). The voice authentication system uses acoustic signals to identify users, substituting the mechanical interaction of typing passwords with natural voice commands, thereby enhancing security while maintaining user convenience

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

Solution Approach 2:

The patent changes the authentication parameter from static information (passwords that users type) to dynamic biometric parameters (voice characteristics that naturally vary). By using voiceprint features such as pitch, tone, and speech patterns that change with each utterance, the system achieves higher reliability while the automated voice processing keeps the complexity manageable

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If voiceprint authentication is implemented, then the security and accuracy of user verification is improved, but the authentication process time and system complexity increase

Engineering Contradiction:
Improveuser identity verification accuracyVSAvoidauthentication process time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-collecting and storing voiceprint templates during user registration before actual authentication is needed. When authentication is required, the system only needs to compare the new voice sample against the pre-stored template, significantly reducing the time required during the actual authentication process while maintaining high verification accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by creating a digital replica (voiceprint template) of the user's voice characteristics during registration. This template serves as a reference copy that can be quickly compared against future voice samples, enabling fast and accurate authentication without requiring complex real-time analysis of raw voice signals

Inventive Principle:
Principle #26Copying

AI summary

The present disclosure discloses a method and an apparatus for authenticating a user. A specific embodiment of the method comprises: receiving an authentication request sent by a user terminal, wherein the authentication request comprises a user identification of a user of the user terminal and operation information related to user operation; determining whether the user operation matches a preset to-be-authenticated operation according to the user identification and the operation information; sending voicing material to the user terminal for reading by the user in response to determining that the user operation matches the preset to-be-authenticated operation, so that the user terminal acquires corresponding authentication voice of the user; receiving the authentication voice sent by the user terminal; and authenticating the user according to the user identification and the authentication voice.
