Graded Voice Password Authentication via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice encryption methods require users to input multiple different voice passwords for graded security verification, leading to a tedious user experience and increased likelihood of forgetting or confusion.
Innovation Solution
Establishing a corresponding relationship between security grades and voice passwords, where each voice password is a part or all of a preset password, allowing users to input the preset password once to access various security grades based on predefined length truncations, simplifying the verification process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple different voice passwords are required for different security grades, then security verification can be performed at different levels, but user operation complexity increases and user experience deteriorates
Solution Approach 1:
The voice password is segmented into multiple portions, where each portion corresponds to a different security grade. The system divides the complete voice password into N portions, with each portion being usable for authentication at a specific security level, allowing users to access different security grades without needing to remember multiple separate passwords
Solution Approach 2:
A single voice password serves multiple functions by providing access to different security grades. The complete voice password can be used for the highest security grade, while portions of it can be used for lower security grades, making one password structure serve multiple authentication purposes
2Adaptability or versatility
If multiple different voice passwords are required for different security grades, then graded cipher management is achieved, but the quantity of information to remember increases
Solution Approach 1:
The voice password information is segmented into N portions, where each portion corresponds to a specific security grade. This segmentation allows the system to manage graded cipher access while reducing the information burden on users, as they only need to remember one complete voice password instead of multiple separate passwords
Solution Approach 2:
The system pre-divides the voice password into multiple portions during setup, so that when authentication is needed, the user simply provides the complete voice password and the system automatically determines which portion to use based on the required security grade, eliminating the need for users to pre-remember multiple different passwords

AI summary
Provided are a method and apparatus for managing a graded cipher. The method includes that: a corresponding relationship between different security grades and corresponding voice passwords is established, herein the voice password corresponding to each security grade in the corresponding relationship is a part or all of a preset voice password; and a voice password is received from a user, and the obtained corresponding relationship is searched for the security grade corresponding to the voice password matched with the received voice password.
