Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional biometric devices are used for authentication, then user identification can be performed, but security vulnerabilities arise from fake inputs such as pictures or molds
Solution Approach 1:
The patent combines multiple authentication modalities (fingerprint recognition, facial recognition, or other biometric methods) with liveness detection technology into a unified authentication system. This integration ensures that both identity verification and liveness confirmation are performed together, preventing fake inputs from bypassing security while maintaining user convenience.
Solution Approach 2:
The patent introduces an intermediary liveness detection mechanism that acts as a mediator between the user and the authentication system. This intermediary layer analyzes physiological signals (such as blood flow, skin temperature, or micro-expressions) to determine whether the user is genuinely present, thereby blocking fake inputs without requiring changes to the core biometric authentication process.
2Reliability
If multiple authentication layers are added to prevent fake inputs, then security is improved, but system complexity increases
Solution Approach 1:
The patent segments the authentication process into distinct modular components: identity verification module and liveness detection module. Each module operates independently but contributes to the overall authentication decision. This segmentation allows the system to maintain high security through multiple layers while managing complexity through modular design, where each component can be developed, tested, and maintained separately.
3Reliability
If complex ECG-based biometric authentication is implemented, then robust security against fake inputs is achieved, but computational complexity and processing time increase
Solution Approach 1:
The patent implements partial ECG-based authentication by measuring only specific physiological parameters (such as heart rate variability or specific waveform characteristics) rather than performing complete ECG analysis. This approach provides sufficient liveness detection capability to prevent fake inputs while significantly reducing computational complexity and processing time compared to full ECG-based authentication systems.
