Anti-counterfeiting Article with HVS Texture Camouflage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-counterfeiting measures are costly, complex, and do not facilitate quick, unobtrusive detection for trained inspectors, who need to identify counterfeit products without drawing attention, as crude counterfeiting methods like offset presses produce indistinguishable packages.
Innovation Solution
Incorporating a human visual system (HVS)-perceivable target with a surrounding texture that provides gentle stimulus modulation, where the target has higher saliency than the texture, allowing the texture to camouflage the target, and its location is determined by serial numbers or other information, enabling quick and unobtrusive detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If marking products with serial numbers and fluorescent inks is done, then anti-counterfeiting protection is improved, but detection speed and unobtrusiveness deteriorate
Solution Approach 1:
The patent uses color changes in the human visual system by employing a target with higher saliency color than the surrounding texture. The texture produces gentle HVS stimulus modulation while the target maintains higher color saliency, enabling quick detection through color contrast without requiring inspectors to search for serial numbers or fluorescent markers.
Solution Approach 2:
The patent creates a visual copy of the product package featuring a target surrounded by texture. This visual copy encodes anti-counterfeiting information through the spatial relationship between the target and texture, allowing inspectors to quickly identify counterfeit products by recognizing the pattern rather than searching for traditional markers.
2Reliability
If marking products with holograms and micro-displacement of glyphs is done, then anti-counterfeiting protection is improved, but packaging complexity and cost increase
Solution Approach 1:
The patent applies local quality by creating a specific visual pattern where a target element is surrounded by texture with different HVS stimulus modulation. This localized pattern encoding provides anti-counterfeiting protection through the specific spatial relationship between target and texture, avoiding the need for complex holograms or micro-displacement glyphs while maintaining security.
Solution Approach 2:
The patent uses parameter changes in the visual system by manipulating the saliency and stimulus modulation parameters of the target and texture. By adjusting these visual parameters, the patent creates an anti-counterfeiting mechanism that is simple to implement but effective, avoiding complex packaging modifications.
3Ease of manufacture
If crude counterfeiting with offset presses is used, then counterfeiting cost is reduced, but product distinguishability deteriorates
Solution Approach 1:
The patent employs asymmetry by creating an uneven visual pattern where a distinct target is surrounded by texture. This asymmetric pattern is difficult for crude counterfeitors using offset presses to replicate accurately, as the specific spatial relationship between the target and texture requires precise positioning that is costly to produce, thereby distinguishing legitimate products from counterfeits.
Data Source
AI summary
An object is protected against counterfeiting by an article including an HVS-perceivable target and HVS-perceivable texture surrounding the target. The texture produces a gentle HVS stimulus modulation. Color of the target has a higher saliency than that of the texture, whereby the texture provides camouflage for the target. Location of the target with respect to the texture is a function of a serial number or other information about the object.
