Security Element Partial Elements Alignment Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passport forgeries occur when the data page is removed from one passport and inserted into another, causing the visa pages and cover to no longer match the data page, leading to a need for a method to verify the correct combination of carrier parts in identity documents.
Innovation Solution
A security element is produced with movable partial elements that align and overlay each other, using electromagnetic waves to create authenticity information items, ensuring the correct assignment of carrier parts by processing one element directly and the other indirectly, allowing for the production of distinct partial information items that represent the authenticity information when combined.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the data page is removed from one passport and inserted into another, then the data page can be reused, but the visa pages and cover no longer match the data page
Solution Approach 1:
The security element is divided into multiple partial elements (first partial element, second partial element, third partial element) that are distributed across different carrier parts (cover, data page, visa pages). Each partial element contains a portion of the authenticity information, and they must be correctly assembled to reveal the complete authentic message. This segmentation prevents forgery because removing and reinserting a data page would separate the partial elements, making it impossible to reconstruct the complete authenticity information.
2Reliability
If multiple partial elements are distributed across different carrier parts, then authenticity verification is enabled, but the complexity of producing and assembling the security element increases
Solution Approach 1:
The patent replaces complex mechanical assembly mechanisms with an optical/information-based system. Instead of using intricate mechanical interlocking or alignment features, the security element uses optical transparency and information encoding. The processing means uses electromagnetic radiation to create transparent or translucent regions in the partial elements that allow visual verification when correctly assembled. This substitution of mechanical complexity with optical simplicity enables authenticity verification while reducing production complexity.
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
This method allows for simple and effective production of partial information items that, when combined, represent an authenticity information item, enabling easy verification of the correct assignment of carrier parts, thereby detecting any manipulation or mismatch.
Implementation Method 1
In a processing step, electromagnetic waves are provided by at least one processing means with which waves the first partial information item and the second partial information item are produced, wherein one of the two partial elements is processed directly with said waves, and the other of the two partial elements is processed through said one partial element
Data Source
AI summary
A method for producing an authenticity information item of a security element, which serves for checking the correct combination of carrier parts. The security element comprises at least one first partial element having a first partial information item and a second partial element having a second partial information item. The two partial elements are movable into a check position, in which the two partial elements overlay one another. The information items in the check position represent the information item. In an alignment step, the two partial elements are provided with at least one processing means, with which waves the first partial information item and the second partial information item are produced. One of the two partial elements is processed with the waves directly, and the other of the two partial elements is processed through the one partial element.
