Voiceprint and Voice Password Identity Verification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional voiceprint verification technologies cannot determine whether an inputted voice is made by a real person, making them vulnerable to identity theft through voice imitation.
Innovation Solution
A system and method that combines voiceprint identification with voice password verification, using a voice receiving module, voiceprint identification module, voice identification module, prompting module, and operation executing module to ensure that the voice signal matches a pre-built target voiceprint and a predetermined command before allowing access, thereby enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If voiceprint verification technology is used to determine speaker identity, then the speaker's voice can be used to determine the speaker's identity, but the technology is unable to distinguish whether the voice is made by a real person or is played by an audio player
Solution Approach 1:
The patent combines voiceprint verification with voice password verification into a unified identity determination system. The voiceprint identification module extracts acoustic features from the voice signal, while the voice identification module checks whether the voice content matches a predetermined command. Both verification results must be positive for the system to determine that the voice is authentic, thereby preventing audio playback attacks while maintaining accurate speaker identification.
2Ease of operation
If voiceprint verification is used for identity determination, then speaker identification can be achieved, but a person with malicious intent may record the voice of the speaker to obtain the voiceprint of the speaker in advance and steal the identity of the speaker
Solution Approach 1:
The system performs preliminary verification by checking whether the voice content matches a predetermined command before completing identity determination. This preliminary check acts as a preventive measure against voice recording attacks, as the system requires not only that the voiceprint matches but also that the voice content is authentic and not a playback of a recorded command.

AI summary
A system of determining identity based on voiceprint and voice password, and a method thereof are disclosed. In the method, after the voice signal is received, the judgment result of the voiceprint of the voice signal and the judgment result of the content of the voice signal are used to determine whether to pass the verification, and this technical solution of the present invention can confirm that the voice, identified based on the voiceprint thereof, is made by a real person, so as to improve the security of identity determination.
