Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional identity authentication only compares physiological characteristics, then the authentication process is simple and fast, but it becomes vulnerable to identity theft and spoofing attacks
Solution Approach 1:
The patent segments the authentication verification into multiple independent components: physiological characteristic comparison, motion record analysis, and time interval verification. Each component processes a specific aspect of user behavior, allowing the system to comprehensively authenticate identity while maintaining modular architecture that manages complexity.
Solution Approach 2:
The patent adds temporal and motion dimensions to traditional physiological characteristic authentication. By incorporating time intervals between scans and motion patterns during scanning, the system transforms static physiological data into dynamic multi-dimensional authentication evidence, significantly improving reliability against spoofing attacks.
2Measurement precision
If multiple physiological characteristics and motion records are scanned and compared, then authentication accuracy improves, but the scanning time and processing complexity increase
Solution Approach 1:
The patent performs preliminary actions by pre-establishing time interval thresholds and motion record criteria during system setup. During actual authentication, the system only needs to verify whether measured values fall within predetermined ranges, significantly reducing real-time processing complexity while maintaining high authentication accuracy.
Solution Approach 2:
The system uses the user's own natural behavior patterns (normal time intervals between authentication attempts and characteristic motion patterns during scanning) as authentication criteria. This self-service approach leverages inherent user behavior without requiring external reference data or complex comparison algorithms, improving accuracy while minimizing processing time.
3Reliability
If time interval verification is added to authenticate user identity, then security against spoofing improves, but the authentication process becomes more complex
Solution Approach 1:
The patent introduces time interval records as an intermediary verification layer between physiological characteristic scanning and final authentication decision. This intermediary component translates complex temporal analysis into simple threshold comparisons, improving anti-spoofing security while keeping the verification process manageable through standardized comparison operations.
