Optical Marking Verification for Glass Container Authenticity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for marking glass items, such as hot-marking and safety labels, fail to ensure the authenticity of the marking as they can be replicated on counterfeit items, leading to difficulties in identifying unique glass containers during recycling and traceability processes.
Innovation Solution
A method that involves identifying the position and shape of markings on glass containers, correlating these characteristics in a database, and using an optical detection system to verify the authenticity of the markings by measuring intrinsic characteristics like depth and curvature of cavities, thereby distinguishing between original and counterfeit items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hot-marking or safety labels are used to mark glass items, then the marking cannot be removed without damage or tearing, but the marking can be replicated on counterfeit items
Solution Approach 1:
The invention changes the parameters used for identification from the marking content itself to the marking's physical characteristics (position coordinates and shape parameters). By recording the precise position (x, y, z coordinates) and shape parameters of the marking, the system creates a unique identifier that cannot be replicated even if the marking content is copied, thus resolving the contradiction between marking security and unique identification capability
Solution Approach 2:
The invention replaces the traditional approach of relying on marking content or physical attachment security with an optical measurement and data correlation system. An optical system measures the marking's position and shape, and a database correlates these measurements with item identification, substituting mechanical marking security with an information-based identification system that provides unique verification
2Quantity of substance
If the same marking is copied on counterfeit items, then the marking appears identical, but the position and shape show slight inaccuracies
Solution Approach 1:
The invention implements a feedback mechanism where the optical system continuously measures the actual position and shape of markings, compares them against reference data stored in the database, and uses this comparison to identify counterfeit items. The system measures marking characteristics, processes the data through correlation algorithms, and provides feedback that enables authentication decisions, creating a closed-loop verification system

AI summary
Disclosed is a method for associating a marking with an object, including the following steps: —identifying the position of at least two different elements of the marking in relation to the marking and/or the object; and—measuring a relative distance between at least two identified elements; then—recording in a database the position of at least two identified elements, and the relative distance between the identified elements so that the position of two identified elements is correlated with the measurement relating to their distance.
