Voice Biometrics Authentication for Data Network Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional access control systems in data networks, especially in high-risk applications like internet and mobile services, face challenges with knowledge-based security measures such as password and PIN systems, which are prone to loss and unauthorized access, and supplementary possession-based methods like tokens can be costly and inefficient.
Innovation Solution
A voice biometrics-based authentication process using a dedicated client on the user's terminal to process and compare voice samples for secure access control, eliminating the need for complex passwords and additional hardware, and serving as a second factor or standalone two-factor authentication method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If knowledge-based authentication schemes (passwords, PINs) are used, then access control can be implemented, but security is compromised due to loss and unauthorized access risks
Solution Approach 1:
The patent replaces knowledge-based authentication (passwords, PINs) with voice biometrics authentication. Instead of relying on memorized information that can be lost or stolen, the system uses voice recognition to verify user identity. The voice sample is processed through feature extraction and comparison with stored profiles to authenticate the user, eliminating the need for passwords that can be lost or intercepted.
2Reliability
If possession-based authentication means (tokens, hard tokens) are added, then security is enhanced, but cost burden increases and implementation complexity grows
Solution Approach 1:
The patent extracts the authentication function from complex possession-based systems and implements it through voice biometrics. Instead of requiring physical tokens, smart cards, or hard tokens that need to be managed, distributed, and secured, the system uses the user's voice as a natural biological identifier. This eliminates the need for additional hardware and simplifies the authentication process while maintaining security.
3Reliability
If voice-based authentication is implemented, then access control security is improved, but processing time and system resources are consumed
Solution Approach 1:
The patent implements preliminary action by pre-processing and storing voice profiles of authorized users before actual authentication is needed. During enrollment, voice samples are collected, processed, and stored as reference profiles. During authentication, the system only needs to compare the new voice sample against the stored profile using feature extraction and pattern matching, which is much faster than analyzing complete voice recordings from scratch.

Data Source
AI summary
Process for controlling the access of a user to a service provided in a data network, to protect user data stored in a data base of the service from unauthorized access, the method comprising: (a) inputting, in a VoIP session, a voice sample of the user at a user data terminal which is at least temporarily connected to the data network, (b) processing, in a first processing step, the user's voice sample using a dedicated client implemented at the user data terminal, to obtain a pre-processed voice sample or a current voice profile of the user, (c) further processing, in a second processing step, the pre-processed voice sample or the current voice profile, including a comparison step of the current voice profile with an initial voice profile stored in a data base, and (d) outputting an access control signal for granting or rejecting access to the service, taking the result of the comparison step into account.
