Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact-based fingerprint authentication is used, then authentication capability is provided, but health risks increase due to germ transmission and security vulnerabilities arise from fingerprint lifting
Solution Approach 1:
The patent replaces contact-based mechanical fingerprint sensing with optical imaging technology. A camera captures images of the user's palm, and image processing algorithms extract palm print patterns without physical contact. This substitution eliminates germ transmission risks while maintaining authentication capability through non-contact palm print recognition.
Solution Approach 2:
The patent introduces an intermediary imaging system between the user and the authentication mechanism. Instead of direct finger contact with a sensor, the system uses camera-based imaging as an intermediary to capture palm patterns, process them to extract identification features, and compare them against stored templates. This intermediary approach eliminates direct contact while preserving authentication functionality.
2Reliability
If multiple user IDs and passwords are required for different applications and resources, then access control precision is improved, but ease of operation deteriorates due to memory burden and forgotten credentials
Solution Approach 1:
The patent implements a universal authentication system where a single palm print credential can access multiple different resources and applications. The centralized authentication server validates palm prints and issues dynamic access tokens that work across various services, eliminating the need for separate credentials for each application while maintaining secure access control.
Solution Approach 2:
The patent creates a biometric copy of the user's palm print pattern as a permanent authentication identifier. This unique palm print template is stored securely and can be used to authenticate access to multiple resources without requiring the user to remember multiple passwords. The system copies the essential authentication feature (palm pattern) while eliminating the burden of managing multiple credentials.
3Ease of manufacture
If textual passwords are used for access control, then implementation simplicity is maintained, but security deteriorates due to hacking capabilities and credential theft
Solution Approach 1:
The patent replaces textual password verification with optical biometric verification. Instead of checking text strings that can be stolen or cracked, the system captures optical images of palm prints, extracts unique pattern features, and compares them against stored templates. This substitution provides stronger security while maintaining relatively simple implementation through standard camera and image processing technology.
Solution Approach 2:
The patent changes the authentication parameter from textual strings to optical biometric patterns. The system transforms the authentication domain from discrete text characters to continuous optical pattern recognition, making credentials impossible to type incorrectly or steal through traditional means. The palm print's unique optical characteristics provide inherent security that text passwords cannot achieve.
4Ease of operation
If physical keys are provided for facility access, then ease of operation is improved, but security deteriorates due to key copying and unauthorized sharing
Solution Approach 1:
The patent replaces physical keys with digital palm print credentials that exist only as data templates. The authentication system stores encrypted palm print patterns and validates them through image comparison, eliminating the ability to copy physical keys. Access is granted through secure digital verification that cannot be replicated without the original biometric template.
Solution Approach 2:
The patent substitutes mechanical physical keys with optical biometric authentication. Instead of inserting a physical key into a lock, the user positions their palm for imaging, and the system optically captures and verifies the palm print pattern. This substitution maintains ease of access while providing superior security through non-replicable biometric verification.
