Voice Terminal Authentication via Multi-Server Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional voice verification technologies fail to effectively prevent unauthorized use and leakage of personal information, especially in cases of terminal loss or theft, as they lack robust authentication methods and cannot accurately recognize user voices.
Innovation Solution
A voice verification and restriction method for voice terminals that involves storing user voices in multiple authentication servers, analyzing them using a language processing module, and performing step-by-step actions based on user-defined responses to prevent unauthorized access, including function locking and emergency notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If voice information is stored in a single voice authentication server and simply compared, then the authentication process is simple and fast, but the accuracy of voice recognition is insufficient and the terminal is vulnerable to unauthorized use
Solution Approach 1:
The patent divides the voice authentication system into multiple independent voice authentication servers. Each server stores and processes voice information separately, allowing the system to compare results across multiple servers to improve recognition accuracy while distributing the computational complexity across separate entities rather than concentrating it in a single system.
Solution Approach 2:
The patent introduces a language processing module as an intermediary between the microphone and the voice authentication servers. This module pre-processes and analyzes voice information before transmission, enhancing recognition accuracy through additional processing steps while keeping the core authentication logic distributed across multiple servers.
2Reliability
If functions of the terminal are locked to prevent unauthorized use, then security is improved, but the terminal cannot be used when lost or stolen without proper authentication
Solution Approach 1:
The patent implements preliminary voice information registration and authentication setup before the terminal is lost or stolen. By pre-configuring multiple authentication servers with user voice data and establishing authentication protocols in advance, the system ensures that security measures are already in place and can be immediately activated without disrupting normal terminal usage when needed.
Solution Approach 2:
The patent changes the authentication parameter from simple voice comparison to a multi-server verification process with language processing analysis. This parameter change enhances security by requiring multiple verification points while maintaining ease of operation through automated processes that users interact with naturally through voice commands.
3Reliability
If multiple voice authentication servers are used to compare and verify voice, then voice recognition accuracy and security are improved, but the authentication process becomes more complex and time-consuming
Solution Approach 1:
The patent performs preliminary voice information analysis and processing in the language processing module before distributing queries to multiple authentication servers. This pre-processing reduces the complexity of individual server tasks and enables parallel processing across servers, improving security through multi-server verification while minimizing additional authentication time through efficient workflow design.
4Measurement precision
If a language processing module is used to analyze voice information, then voice recognition accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent positions the language processing module as an intermediary layer between the microphone and the voice authentication servers. This intermediary performs specialized voice analysis functions that enhance recognition accuracy while keeping the core authentication logic separate and distributed across multiple servers, allowing each component to specialize in its specific function without duplicating complexity throughout the entire system.

AI summary
A voice verification and restriction method of the voice terminal includes: a) voice storage step including: inputting and registering voice of a user through a microphone of the voice terminal, receiving and analyzing the input voice using a language processing module, transmitting the analyzed voice to a plurality of voice authentication servers to verify and store each voice, and learning the stored voice using an AI processor; and b) voice verification step including: mutually comparing the input voice with voice stored in at least one server among voices stored in the plurality of voice authentication servers, performing approval and a voice command when the input voice matches the stored voice, and setting restrictions on all or some of functions of the voice terminal and executing a step-by-step action designated by the user when the input voice does not match the stored voice.
