Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional ID and password authentication is used, then ease of operation is improved, but security reliability deteriorates due to vulnerability to hacking
Solution Approach 1:
The patent combines multiple biometric authentication methods (fingerprint, iris, voice, face recognition) into a unified authentication system. This merging of different biometric modalities creates a more secure authentication mechanism while maintaining user convenience through automated processing.
Solution Approach 2:
The patent uses composite polynomial construction combining features from multiple biometric sources (first biometric information and second biometric information) to create a composite authentication credential. This composite approach enhances security by requiring multiple biometric characteristics to be validated simultaneously.
2Reliability
If multiple types of biometric information are collected and processed, then security reliability is improved, but device complexity increases
Solution Approach 1:
The patent divides the biometric authentication system into distinct modules: first biometric information acquisition, second biometric information acquisition, feature extraction, polynomial construction, and authentication verification. This segmentation allows each component to be optimized independently while maintaining overall system security.
Solution Approach 2:
The patent introduces composite polynomials as an intermediary mathematical representation that transforms raw biometric data into a standardized authentication format. This intermediary structure simplifies the comparison process and reduces the complexity of directly handling multiple biometric data types.
3Productivity
If a small amount of biometric information is used, then processing speed is improved, but authentication accuracy may deteriorate
Solution Approach 1:
The patent transforms biometric information into polynomial parameters through feature extraction and mathematical transformation. This parameter change allows the system to work with compact numerical representations that are both space-efficient and computationally fast to process, while maintaining authentication accuracy through the mathematical properties of polynomial construction.
