Article Authenticity Confirmation via Surface Irregularities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for confirming the authenticity of articles, such as using non-contact IC chips or irreproducible fine characteristics, face challenges including high costs, vulnerability to forgery once manufacturing techniques are learned, and difficulty in applying to shape-changing materials like fabrics and leathers due to precision and stability issues.
Innovation Solution
An article confirmation method that reads and compares irreproducible fine characteristics, such as random patterns, using a device with a reading unit and protection material to stabilize and protect the patterns, allowing for precise authenticity determination without the need for additional components like IC chips or special inks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If non-contact IC chips are embedded in articles for authenticity confirmation, then convenience is improved (no contact needed), but manufacturing cost increases and device complexity increases
Solution Approach 1:
The invention extracts the authenticity confirmation function from complex embedded systems (IC chips) and implements it using only the article's inherent surface characteristics. By reading irregularities directly from the article surface without any embedded components, the system achieves convenience while eliminating the need for complex manufacturing and reading devices.
Solution Approach 2:
The article itself serves as the authentication element through its unique surface irregularities, eliminating the need for external authentication components. The surface characteristics automatically provide the authentication data when scanned, making the system self-sufficient and reducing overall complexity.
2Reliability
If IC chips are embedded in articles for authenticity confirmation, then forgery prevention is improved, but manufacturing cost increases
Solution Approach 1:
The invention replaces expensive, permanent authentication components (IC chips) with inexpensive, inherent surface characteristics of the article. The surface irregularities are naturally present and require no additional manufacturing steps, making authentication extremely cost-effective while maintaining security.
Solution Approach 2:
The invention extracts the authentication function from manufactured components and derives it from the article's natural surface characteristics. This eliminates the need for expensive embedding processes while maintaining forgery prevention capabilities through unique, naturally occurring patterns.
3Ease of manufacture
If irreproducible fine characteristics are used for authenticity confirmation, then manufacturing cost is reduced, but measurement precision deteriorates when the article changes shape
Solution Approach 1:
The invention makes the authentication system dynamic by adapting to the article's current shape state. The reading device adjusts to capture surface irregularities regardless of the article's form, allowing accurate authentication even when the article is folded, bent, or deformed, thus maintaining precision while keeping manufacturing simple.

AI summary
An article confirmation method has reading irreproducible fine characteristics from a genuine article, reading irreproducible fine characteristics from an article to be confirmed, comparing the irreproducible fine characteristics between the genuine article and the article to be confirmed, and determining authenticity of the article to be confirmed based on a comparison result.
