Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the authenticity of articles with unique random patterns are either destructive or require complex equipment, making it difficult to preserve the articles and accurately verify their authenticity without external processing.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods are used to determine authenticity, then authenticity verification can be performed, but the articles are destroyed or complex equipment is required
Solution Approach 1:
The patent creates a compressed feature image that serves as a copy of the article's surface pattern. This compressed image contains the essential authenticity information while being much smaller in size, allowing verification without destroying the original article. The copying principle enables non-destructive authentication by working with a digital representation rather than physically altering the article.
Solution Approach 2:
The patent extracts only the essential feature information from the article's surface pattern through compression. By taking out only the necessary features (maintaining continuity in certain directions while removing redundancy), the system achieves authenticity verification without requiring complex equipment or destroying the article. The extraction principle isolates the critical authenticity markers from the overall complex pattern.
2Reliability
If existing methods are used to determine authenticity, then verification can be performed, but complex equipment is required
Solution Approach 1:
The system uses a simple camera to capture an image of the article surface and then creates a compressed version through software processing. This copying approach replaces complex physical measurement equipment with a simple optical device combined with computational algorithms, significantly reducing hardware complexity while maintaining verification accuracy.
Solution Approach 2:
The patent replaces complex mechanical measurement systems with an optical system (camera) combined with digital image processing. Instead of using complex physical instruments to measure article properties, the system uses light capture and computational compression to extract authenticity features, substituting mechanical complexity with optical and algorithmic simplicity.
3Quantity of substance
If feature information is compressed, then data size is reduced, but continuity of feature information may be lost
Solution Approach 1:
The compression process applies different levels of compression to different regions and directions of the feature image. Areas with high feature continuity (important for authenticity) maintain higher quality and less compression, while areas with lower continuity can be more aggressively compressed. This local quality approach preserves critical authenticity information while reducing overall data size.
Solution Approach 2:
The system performs preliminary analysis of the feature image to identify directions and regions of high continuity before applying compression. By preparing and analyzing the image structure in advance, the system can strategically apply compression algorithms that preserve continuity in critical directions while reducing data size in less critical areas, preventing information loss.

Data Source
AI summary
An authenticity determination support device includes an acquiring unit and a compressing unit. The acquiring unit photographs, in a solid having a unique random feature in a surface thereof, a predetermined area in the surface such that continuity of the feature is generated in a predetermined direction, and thereby acquires feature information representing the feature included in the area. The compressing unit compresses the feature information in a direction in which continuity of the feature information acquired by the acquiring unit is high.
