Solution Overview
Problem
Current authentication technologies lack robust and versatile methods for verifying the authenticity of articles using woven patterns, which are not adequately distinguishable or scalable for secure identification.
Innovation Solution
A woven authentication pattern comprising twisted threads with contrasting optical or visual properties, forming spiralling or helical elements, is used in conjunction with a processor-based system to capture and compare images with reference patterns for authenticity verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication methods are used, then implementation is simple, but security and distinguishability are insufficient
Solution Approach 1:
The authentication pattern is segmented into multiple distinct elements including spiralling elements, partitioning elements, and pattern forming elements. Each element serves a specific function in creating a unique, complex pattern that enhances security while maintaining structured organization for verification
Solution Approach 2:
The pattern incorporates asymmetric design through spiralling elements with varying degrees of spiralization, non-uniform distribution of pattern forming elements, and irregular spacing between elements. This asymmetry creates highly distinguishable patterns that are difficult to replicate, thereby enhancing authentication security
2Adaptability or versatility
If woven patterns are used for authentication, then scalability is improved, but distinguishability and security features are insufficient
Solution Approach 1:
Different regions of the woven pattern exhibit distinct local characteristics through variations in element type, spacing, density, and optical properties. Each local region contributes unique features to the overall pattern, enabling both scalability across different authentication devices and high distinguishability through localized variations
Solution Approach 2:
The authentication pattern utilizes composite woven structures combining threads with contrasting optical properties (such as fluorescent and non-fluorescent threads, or threads with different reflectivity). This composite approach enhances both the scalability of the authentication system and the reliability of pattern distinguishability through multi-property characterization
3Ease of operation
If simple patterns are used, then ease of verification is improved, but security and uniqueness are compromised
Solution Approach 1:
The verification system captures an optical image of the complex woven authentication pattern and creates a digital representation for comparison with reference patterns. This copying approach allows sophisticated security features to be verified through simple image capture and computational comparison, maintaining ease of operation while ensuring high authentication uniqueness
Solution Approach 2:
The manual visual inspection process is replaced with automated image processing and pattern recognition algorithms. The system substitutes mechanical/optical verification with computational analysis, enabling complex patterns to be verified easily through automated comparison while maintaining high security and uniqueness standards
