Voiceprint Authentication for Mobile Payment Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile payment methods, such as password and message authentication, are insecure, leading to potential economic losses and poor user experience due to the risk of password compromise.
Innovation Solution
A voiceprint authentication method that compares the user's voiceprint with a registered voiceprint to authenticate identity, eliminating the need for password input and displaying concealed characters based on user preference, enhancing security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password authentication is used for mobile payment, then the operation is simple, but the security is poor
Solution Approach 1:
The patent replaces the mechanical password input system with a voiceprint recognition system. The user's voice is captured and converted into voiceprint features for authentication, eliminating the need for manual password entry while enhancing security through biometric verification.
Solution Approach 2:
The patent introduces voiceprint features as an intermediary between the user and the authentication system. Instead of directly comparing passwords, the system extracts voiceprint features from the user's speech and compares these features to verify identity, adding a layer of security while maintaining ease of use.
2Ease of operation
If password is displayed in plaintext, then the operation is convenient, but the user experience is poor due to psychological concerns
Solution Approach 1:
The patent replaces the visual plaintext password display mechanism with a voice-based authentication mechanism. Instead of showing and typing passwords, the system captures voice input and processes it through voiceprint recognition, eliminating the psychological discomfort of plaintext exposure while maintaining operational convenience.

AI summary
The present disclosure provides a voiceprint authentication method and a voiceprint authentication apparatus. The method includes: displaying (101) a first character string to a user, in which the first character string includes a predilection character preset by the user, and the predilection character is displayed as a symbol corresponding to the predilection character in the first character string; obtaining (102) a speech of the first character string read by the user; obtaining (103) a first voiceprint identity vector of the speech of the first character string; comparing (104) the first voiceprint identity vector with a second voiceprint identity vector registered by the user to determine a result of a voiceprint authentication.
