Biometric Contact Filtering for Mobile Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals face inconvenience and poor privacy protection due to repeated unlocking requirements, which disrupt user experience and do not effectively prevent unauthorized access to sensitive information.
Innovation Solution
Implementing a biometric recognition system that detects and matches user biometric characteristics with preset data to determine whether to display sensitive contact information, allowing authorized users to access designated contact information while hiding it from others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gesture/digital lock is used to protect privacy, then privacy protection is improved, but user convenience deteriorates due to repeated unlocking requirements
Solution Approach 1:
The system automatically performs biometric recognition and contact information filtering without requiring user intervention. The terminal device autonomously identifies the current user through biometric characteristics and displays appropriate contact lists, eliminating the need for manual unlocking operations while maintaining privacy protection.
Solution Approach 2:
The patent replaces the mechanical gesture/digital lock system with a biometric recognition system. Instead of requiring users to perform sliding gestures or enter digital passwords, the system uses biometric characteristics (fingerprint, facial recognition, iris, etc.) for automatic authentication and contact information management.
2Ease of operation
If biometric recognition is implemented, then user convenience is improved by reducing repeated unlocking, but device complexity increases
Solution Approach 1:
The biometric recognition system serves multiple functions: it identifies the current user, automatically filters contact information, and manages display content. This multi-functional approach consolidates what would otherwise require separate systems for authentication and contact management, reducing overall system complexity despite the advanced biometric capabilities.

AI summary
An information display method including: detecting a biometric characteristic of a current user of a terminal; determining whether the biometric characteristic matches a preset biometric characteristic; and determining, based on a judgment result, whether to display first information of a designated contact in the terminal.
