Laser-Engraved Security Feature on Textile Passport Connecting Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional passport book constructions are not sufficiently secure against data page exchange and manipulation, making it difficult to detect forgery.
Innovation Solution
A data carrier system featuring a textile or flexible connecting element with a laser-engraved security feature that integrates information components on both the data page and the connecting element, ensuring that the security feature is destroyed when the data page is exchanged, thereby making counterfeiting visible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a data page is inserted into a passport book using a textile or flexible connecting element, then the data page can be turned over like a normal page, but the construction is not sufficiently secure against data page exchange and manipulation
Solution Approach 1:
The patent merges the security feature directly into the connecting element by laser-engraving it onto the textile or flexible material. This integration ensures that the security feature cannot be separated from the connecting element, and thus cannot be transferred to a counterfeit data page. The security feature becomes an inherent part of the mechanical connection structure.
Solution Approach 2:
The security feature is laser-engraved onto the connecting element during the manufacturing process, before the data page is inserted into the passport book. This preliminary creation of the security feature ensures it is permanently associated with the original data page and connecting element combination, making any subsequent manipulation or exchange detectable.
2Ease of manufacture
If conventional constructions are used without integrated security features in the connecting element, then manufacturing is simpler, but it is difficult to detect forgery when data pages are exchanged
Solution Approach 1:
The laser-engraving process creates visual changes in the connecting element through color variations, burning patterns, or material transformation. These visual changes form the security feature that can be easily detected by inspectors during verification, allowing them to identify whether a data page has been exchanged or manipulated.
Solution Approach 2:
The connecting element acts as an intermediary carrier of the security feature. Instead of placing security features directly on the data page (which could be copied), the security feature is placed on the connecting element that physically attaches the data page to the passport. This intermediary position makes the security feature difficult to replicate without the original connecting element.
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
The system significantly enhances security against data page replacement by creating a seamless security feature that is difficult to replicate, thus preventing forgery and ensuring the authenticity of the data carrier.
Implementation Method 1
An overlapping area between the data page and the connecting element can be processed with a laser and laser-engraved according to the invention
