Voiceprint Login System with Dynamic Character Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional login methods using passwords or gestures are insecure due to ease of compromise and memory burdens, while voiceprint authentication is unreliable due to environmental noise and channel differences, particularly in sensitive fields like finance.
Innovation Solution
A voiceprint login method using artificial intelligence that generates a login string with character replacements based on user preferences, allowing users to read and authenticate via speech recognition, combining voiceprint authentication with character replacement for enhanced security and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional password or gesture login is used, then the login process is simple and familiar to users, but the security is poor because passwords can be easily compromised and users must remember multiple complex passwords
Solution Approach 1:
The patent combines voiceprint authentication with character replacement technology into a unified login system. The voice authentication module captures and verifies voice characteristics, while the character replacement module dynamically substitutes characters in login strings based on user preferences and security requirements. This merging creates a multi-layered authentication mechanism that simultaneously improves security through voice verification and simplifies operation by allowing users to define custom replacement rules once, which then apply automatically to all login attempts.
2Reliability
If voiceprint authentication is used alone, then the operation is simple for users, but the reliability is poor due to environmental noise and channel differences affecting recognition accuracy
Solution Approach 1:
The system merges voice authentication with character replacement verification to create a hybrid authentication mechanism. The voice module captures speech and extracts voiceprint features, while the character replacement module provides an additional verification layer by comparing the transcribed text against the expected login string with customized character substitutions. This combination compensates for voice recognition limitations caused by noise or channel variations, as the character verification provides redundancy that improves overall reliability without requiring a completely complex new system.
Solution Approach 2:
The character replacement system acts as an intermediary verification layer between the voice recognition module and the authentication decision. When voice recognition transcribes user input, the system applies character replacement rules to both the transcribed text and the expected login string, then compares them. This intermediary processing step helps bridge gaps caused by environmental noise or recognition errors, as the replacement rules provide a standardized transformation that both sides must satisfy, thereby improving reliability without directly modifying the voice recognition algorithm itself.
3Reliability
If multiple complex passwords with special characters are set for different objects, then the security is improved, but the memory burden for users increases significantly
Solution Approach 1:
The system implements self-service through automated character replacement rules that users configure once during setup. Instead of requiring users to manually create and remember multiple complex passwords, the system automatically applies user-defined replacement rules to generate secure login strings. For example, a user might define that certain characters should be replaced with symbols or other characters, and the system automatically applies these rules to all login scenarios. This eliminates the need for users to memorize multiple complex passwords while maintaining high security through the automated generation of unique, secure login strings for each object.
Solution Approach 2:
The system changes the parameter of password complexity from a static requirement (users must create complex passwords) to a dynamic transformation (system automatically applies replacement rules). By parameterizing the character replacement behavior based on user preferences and security policies, the system generates secure but memorable login strings. The same base password can be transformed into different secure variants for different objects through parameter-based character replacement, eliminating the need for users to remember multiple complex passwords while maintaining high entropy and security.

AI summary
Disclosed is an artificial intelligence based voiceprint login method. The method comprises: S1: receiving a login request from a user and acquiring user information of the user; S2: generating a login string and replacing at least one character in the login string according to character replacement control information corresponding to the user information; S3: providing the user the replaced login string and receiving voice information of a login string read by the user; and S4: performing login authentication on the user according to the voice information of the login string read by the user. The method on one hand increases voiceprint password security by combining a voiceprint and user-defined characters to replace a voiceprint authentication corresponding to normal information, on the other hand, the method hides characters that a user wishes to hide to satisfy a psychological need of the user in which the user may not wish to directly show all the passwords, improving user experiences and increasing password security. Also disclosed is an artificial intelligence based voiceprint login device.
