Mobile Terminal Biometric Privacy Protection via Content Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal privacy protection methods are either complex to set up, easily perceived by users, or fail to protect privacy when applications are used, lacking convenience and efficiency.
Innovation Solution
A method that actively obtains a user's biometric feature upon application start or unlock, displaying encrypted and unencrypted content lists based on biometric matching, ensuring privacy protection without user perception, using features like facial, iris, or fingerprint recognition, and geographic location information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual data is returned when the mobile terminal is in privacy protection mode, then privacy can be protected, but the setting is complex and tedious
Solution Approach 1:
The patent extracts the privacy protection function from complex virtual data settings and implements it through biometric authentication. When biometric verification fails, the system automatically returns virtual data without requiring users to manually configure what data to display, thus extracting the essential protection function while removing setting complexity.
Solution Approach 2:
The system performs self-service by automatically determining what virtual data to return based on biometric authentication results. The terminal itself manages the privacy protection logic without requiring user configuration, making the system self-sufficient and eliminating the need for complex user settings.
2Reliability
If different authentication manners are set for privacy mode and normal operation mode, then privacy protection can be implemented, but the mode is easily perceived by users
Solution Approach 1:
The patent applies local quality by making the authentication process context-dependent. Biometric authentication is silently performed for specific sensitive applications without alerting the user, while other applications use normal authentication. This localized approach protects privacy in critical areas while maintaining normal operation elsewhere, reducing overall perceptibility.
Solution Approach 2:
The biometric authentication system acts as an intermediary between the user and the application. Instead of directly switching between privacy and normal modes that users can perceive, the biometric mediator silently verifies identity and controls data access, making the protection mechanism invisible to users while maintaining strong security.
3Ease of operation
If authentication information is entered to unlock the lock screen, then the lock screen can be unlocked, but privacy protection cannot be implemented when the user operates an application
Solution Approach 1:
The patent performs preliminary biometric authentication before allowing access to sensitive applications. The system pre-loads and stores biometric data, then automatically verifies it when the user attempts to access protected applications. This preliminary verification ensures privacy protection is already in place before application operation begins, maintaining both convenience and security.
Solution Approach 2:
The biometric authentication system maintains continuous verification capability throughout application operation. Instead of a one-time unlock authentication, the system continuously validates biometric data during application use, ensuring privacy protection persists throughout the entire application operation period while maintaining seamless user experience.
Data Source
AI summary
A mobile terminal privacy protection method includes obtaining an application start instruction, actively obtaining a biometric feature of a user according to the application start instruction, and displaying an encrypted content list and an unencrypted content list of a corresponding application if the obtained biometric feature of the user matches a preset biometric feature. The encrypted content list of the application is generated according to encrypted content in the application, the unencrypted content list of the application is generated according to unencrypted content in the application, and the encrypted content in the application is content that is not presented when the obtained biometric feature of the user does not match the preset biometric feature.
