Laser-Engraved Security Markings for Anti-Counterfeit Documents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security documents lack effective protection against counterfeiting and falsification, particularly in the form of personalizing data that is easily replicable and not inherently secure.
Innovation Solution
A securing element is introduced with a first personalized marking on a substrate, containing a second personalized marking as an unmarked fragment, creating a first identification entry that is both visually and tactilely recognizable, and optionally a third marking for a second identification entry, all produced through laser engraving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personalizing data is placed on security documents using conventional methods, then the documents can be personalized with identification information, but the documents become vulnerable to counterfeiting and falsification
Solution Approach 1:
The patent embeds a second personalized marking containing identification entry 2 inside the first personalized marking containing identification entry 1. This nested structure creates multiple layers of security where the inner marking is hidden within the outer marking, making counterfeiting difficult while maintaining manufacturability through integrated laser processing
Solution Approach 2:
The personalizing data is divided into multiple separate identification entries (identification entry 1 and identification entry 2) placed at different locations within the security document. This segmentation allows for independent verification of different data elements and increases security against falsification
2Reliability
If multiple layers of security markings are added to protect against counterfeiting, then document security improves, but the manufacturing process becomes more complex
Solution Approach 1:
The patent combines multiple security functions into a single integrated laser marking process. The first and second personalized markings are created in one manufacturing step using laser beam processing, merging what would traditionally require multiple separate operations into a unified process that reduces overall system complexity
3Productivity
If conventional laser marking is used for personalization, then the marking process is simple and fast, but the markings are easy to replicate and falsify
Solution Approach 1:
By nesting identification entry 2 within identification entry 1, the patent creates a multi-layered security structure that maintains the speed of conventional laser marking while dramatically increasing falsification resistance. The nested structure requires precise replication of both outer and inner markings, which is difficult to achieve with counterfeit methods
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the security of documents by making personalizing data difficult to replicate and falsify, providing additional layers of protection through unique and complex markings that are both visually and tactilely distinct.
Implementation Method 1
Lasers have been used for many years to personalize documents. Thanks to that, it is possible to make long-lasting and irreversible markings of the document in the form of photolithography or text data
Implementation Method 2
a plastic substrate is blackened using a suitably guided laser beam
