Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with fingerprint sensors face inefficiencies in multi-factor authentication processes, leading to resource waste and user inconvenience due to the need for sequential interfaces, which prolong the authentication time.
Innovation Solution
An electronic device with a touchscreen and fingerprint sensor that provides a user interface for unlocking, allowing simultaneous entry of security information and fingerprint authentication by displaying visual items corresponding to the security information on the fingerprint sensor area, enabling simultaneous identification and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple interfaces are provided for multi-factor authentication, then authentication security is improved, but authentication time and device complexity increase
Solution Approach 1:
The patent combines multiple authentication interfaces (fingerprint sensor interface and touchscreen interface) into a single unified interface. The fingerprint sensor area serves dual purposes: it detects fingerprint patterns for biometric authentication and displays visual items for security information entry. This merging eliminates the need for sequential interface transitions, allowing users to complete both fingerprint-based and security information-based authentication simultaneously in one location, thereby reducing authentication time while maintaining security.
2Reliability
If multiple interfaces are provided for multi-factor authentication, then authentication security is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by enabling the fingerprint sensor area to serve multiple purposes simultaneously. It functions as both a biometric sensor for fingerprint detection and a display area for visual items representing security information. This universal design allows a single component to handle both fingerprint-based authentication and security information entry, eliminating the need for separate dedicated interfaces and reducing overall device complexity while maintaining authentication security.
3Reliability
If sequential authentication interfaces are used, then authentication security is maintained, but user convenience deteriorates
Solution Approach 1:
The patent merges sequential authentication steps into a simultaneous process by combining multiple interfaces into one. Users can interact with both fingerprint sensing and security information entry within the same unified interface area, eliminating the need to navigate between separate screens or interfaces. This significantly improves user convenience by reducing the number of steps and interactions required while maintaining authentication security through the continued use of multiple authentication factors.
