Voice Print Authentication System for Secure Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for speech recognition and speaker identification are segmented, limiting their ability to perform both functions simultaneously, and there is a need for a secure means to authenticate users accessing secure information over networks, as traditional methods are vulnerable to identity theft.
Innovation Solution
A system and method for voice authentication that includes an enrollment process to create a voice print identification and an authentication process using a voice recording, where the voice analysis system compares the client's voice sample to stored voice prints to verify identity, allowing secure access to network information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If speech recognition and speaker identification are implemented as separate systems, then each system can be optimized for its specific function, but the overall system complexity increases and the ability to perform both functions simultaneously is limited
Solution Approach 1:
The patent combines speech recognition and speaker identification into a single integrated system. The speech processing module handles both word recognition and speaker verification using unified algorithms and a single system architecture, eliminating the need for separate systems and reducing overall complexity while maintaining the ability to perform both functions simultaneously.
Solution Approach 2:
The speech processing module is designed with multi-functionality to perform both speech recognition and speaker identification tasks. The system uses universal algorithms that can operate in different modes depending on whether the task is to recognize what was said or to verify who said it, allowing one system to serve multiple purposes.
2Reliability
If traditional authentication methods are used, then implementation is simple, but security against identity theft is vulnerable
Solution Approach 1:
The patent replaces traditional mechanical authentication methods (such as passwords or physical tokens) with a biometric-based voice authentication system. The speaker identification module analyzes unique acoustic characteristics of the user's voice to verify identity, providing enhanced security against identity theft while maintaining user convenience.
3Measurement precision
If speech authentication uses stringent matching, then verification accuracy improves, but processing time increases
Solution Approach 1:
The system performs voice authentication in stages, initially using less stringent matching to quickly eliminate non-matching speakers, then applying more stringent matching only to promising candidates. This partial action approach maintains high verification accuracy while reducing overall processing time by avoiding exhaustive comparison with all possible templates.

AI summary
Systems and methods providing for secure voice print authentication over a network are disclosed herein. During an enrollment stage, a client's voice is recorded and characteristics of the recording are used to create and store a voice print. When an enrolled client seeks access to secure information over a network, a sample voice recording is created. The sample voice recording is compared to at least one voice print. If a match is found, the client is authenticated and granted access to secure information.Systems and methods providing for a dual use voice analysis system are disclosed herein. Speech recognition is achieved by comparing characteristics of words spoken by a speaker to one or more templates of human language words. Speaker identification is achieved by comparing characteristics of a speaker's speech to one or more templates, or voice prints. The system is adapted to increase or decrease matching constraints depending on whether speaker identification or speaker recognition is desired.
