Solution Overview
Problem
Conventional foldable electronic devices typically integrate only one biometric sensor, limiting access restriction approaches and the security of information with varying security levels stored within the device.
Innovation Solution
A foldable display device with two biometric sensors, one in each display region, allowing for enhanced access restriction methods by utilizing multiple biological features for authentication, such as fingerprints, iris recognition, or face features, and enabling different security levels based on matched biological data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only one biometric sensor is integrated in the electronic device, then the device complexity is reduced and manufacturing is easier, but the access restriction approaches are limited and security protection is insufficient
Solution Approach 1:
The patent divides the single biometric sensing function into multiple separate biometric sensors (first biometric sensor and second biometric sensor) positioned at different locations on the display. This segmentation allows each sensor to independently perform authentication, enabling multiple access restriction approaches while maintaining manageable device complexity through modular sensor integration
2Adaptability or versatility
If multiple biometric sensors are integrated in the electronic device, then multiple access restriction approaches are achieved and security is enhanced, but the device complexity increases
Solution Approach 1:
The patent implements multi-functionality by integrating multiple biometric sensors that can perform different authentication functions (fingerprint recognition, iris recognition, face features). Each sensor serves as an independent authentication channel, allowing the device to adapt to different security requirements and provide versatile access restriction approaches for information with varying security levels
3Ease of manufacture
If one biometric sensor is used, then the manufacturing process is simpler, but the protection of information with different security levels is limited
Solution Approach 1:
The patent implements dynamic security by allowing the system to selectively activate different biometric sensors based on the security level of the information being accessed. The controller can dynamically choose which sensor to use for authentication, providing adaptable protection for information with varying security levels while maintaining a standardized manufacturing process for integrating multiple sensor types
