Voice Authentication for Home Network Control Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home network systems are vulnerable to security breaches when controlled through external user terminals, and users face inconvenience due to complex UI configurations, especially when these systems rely on rule-based smart systems rather than AI for user authentication.
Innovation Solution
An electronic apparatus that performs user authentication based on a user voice, using a communication interface, memory, and processor to receive, analyze, and transmit control commands to external devices, enhancing security and simplifying control through AI-driven authentication and command analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authentication is performed through external user terminals using conventional methods, then user control capability is maintained, but security vulnerability increases due to terminal hacking or theft
Solution Approach 1:
The patent replaces conventional mechanical/authentication-based user verification (passwords, PINs, physical device possession) with voice-based biometric authentication. The electronic apparatus extracts voice features from the user's spoken commands and compares them against pre-stored voiceprints, enabling secure authentication without relying on external terminals that can be hacked or stolen.
Solution Approach 2:
The patent introduces voice feature extraction and comparison as an intermediary authentication layer between the user and the control system. Instead of directly trusting external terminals or simple password verification, the system mediates authentication through voice biometrics, verifying the user's identity through acoustic characteristics before allowing device control.
2Measurement precision
If conventional rule-based smart systems are used for user authentication, then system simplicity is maintained, but user preference understanding accuracy decreases
Solution Approach 1:
The patent changes the authentication parameter from simple password verification or basic voice detection to comprehensive voice feature analysis. The system extracts multiple acoustic parameters (frequency, amplitude, timbre, speech patterns) and compares them against stored voiceprints, significantly improving authentication accuracy and user preference understanding while managing complexity through structured processing.
Solution Approach 2:
The patent performs preliminary voice feature extraction and storage during the authentication phase. Voiceprints are captured and stored in advance, and the system pre-processes voice commands by extracting features before comparison, enabling faster and more accurate user preference understanding during actual interaction without adding significant real-time complexity.

AI summary
An electronic apparatus and a controlling method thereof are provided. The electronic apparatus includes a communication interface comprising communication circuitry, a memory, and a processor. The processor is configured to control the electronic apparatus to: receive a user voice for controlling an external device connected to the electronic apparatus from a user terminal through the communication interface, perform user authentication by comparing feature information obtained from the user voice with feature information pre-stored in the memory, obtain a control command for controlling the external device by analyzing the user voice based on the user being authenticated, and control the communication interface to transmit the control command to the external device.
