Multilayer Identification Document Data Page Security Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data pages in identification documents face security gaps and complex manufacturing processes that increase costs and complexity.
Innovation Solution
A multilayer structure for a data page comprising at least one opaque first layer with through openings and a transparent second layer that extends into the openings, forming a security element visible on the edge part and in the openings, thereby enhancing security by repeating the security element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing security element arrangements are used in data pages, then security against tampering is provided, but security gaps remain and manufacturing complexity increases
Solution Approach 1:
The patent merges the security element with the hinge structure by integrating it into the transparent layer that forms both the hinge and the window. This single integrated structure eliminates the need for separate security elements and reduces manufacturing steps while maintaining security against tampering.
Solution Approach 2:
The transparent layer serves multiple functions simultaneously: it forms the hinge structure, creates the window through opening, and carries the security element. This multi-functionality reduces the number of separate components and manufacturing steps required.
2Reliability
If multiple lamination steps are used to manufacture data pages, then security features can be implemented, but manufacturing costs and process complexity increase
Solution Approach 1:
The patent combines multiple manufacturing operations into a single lamination step. The opaque layer, transparent layer with security element, and window formation are all achieved in one process, eliminating the need for multiple sequential lamination steps and reducing both cost and complexity.
Solution Approach 2:
The security element is pre-integrated into the transparent layer before the final lamination process. This preliminary integration ensures that the security feature is already in place and properly positioned, eliminating the need for additional post-processing steps.
3Ease of manufacture
If security elements are placed only on the hinge or only on the data area, then manufacturing is simpler, but security is reduced due to visible gaps
Solution Approach 1:
The security element is positioned to span both the hinge area and the data area continuously. This continuous placement eliminates visible gaps and ensures security coverage across the entire document, while the single-layer integration maintains manufacturing simplicity.

AI summary
The invention relates to a multilayer structure intended to be inserted in an identification document and comprising at least one first layer at least partially opaque forming a data area, the first layer comprising at least one through opening integrally confined by at least partially opaque material of the first layer, and a second layer at least partially transparent extending at least partially on the data area in order to extend into the through opening, the second layer comprising a part extending beyond the first layer and forming an edge part, the second layer comprising at least one element forming a security element, the security element being present and/or visible on and/or in the edge part and in the through opening of the first layer.
