Gaming Substitute Currency Pattern Matching for Counterfeit Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems fail to effectively distinguish between genuine and counterfeit substitute currency for gaming, allowing counterfeit currency to go undetected.
Innovation Solution
The substitute currency features a unique, naturally formed ground pattern and multi-layered structure with individually identifiable IDs, combined with a management system that uses image analysis and database association to verify authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a unique ID is registered in a database to detect counterfeit currency, then the ability to identify counterfeit currency improves, but the system cannot directly distinguish between genuine and fake currency when only counterfeit currency is used
Solution Approach 1:
The system performs preliminary registration of ground patterns from genuine currency during manufacturing. These pre-stored patterns serve as reference standards that enable direct comparison with unknown currency samples, allowing the system to definitively determine authenticity rather than merely detecting anomalies.
Solution Approach 2:
The system creates a digital copy (image) of the ground pattern from physical currency samples during manufacturing and stores it in the database. This digital copy serves as a reference that can be compared with images of unknown currency, enabling direct authentication without requiring physical possession of genuine currency.
2Ease of manufacture
If ground patterns are made difficult to distinguish at first glance, then the aesthetic quality and difficulty of counterfeiting improve, but the ability to detect and measure patterns becomes more difficult
Solution Approach 1:
The system replaces manual visual inspection with automated image acquisition devices (cameras) and computer-based pattern recognition algorithms. This substitution enables precise measurement and comparison of subtly different ground patterns that would be difficult to distinguish to the human eye, while maintaining the aesthetic quality and counterfeit resistance of the patterns.

AI summary
The management system for substitute currency includes a pattern acquiring device configured to acquire an image of the ground pattern of the substitute currency, a reading device configured to read an ID of the substitute currency, and a control device configured to associate a pattern of the ground pattern with the ID and store the associated pattern and ID in a database. The control device is configured to analyze the image of the ground pattern acquired by the pattern acquiring device to identify the pattern, and determine, based on the database, whether the pattern of the ground pattern of the substitute currency matches the pattern of the ground pattern associated with the ID of the substitute currency obtained from the reading device, thereby to determine authenticity of the substitute currency.
