Split Security Element for Passport Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Identity documents, such as passport booklets, face challenges in verifying the correct assignment of carrier parts, particularly when the data page is manipulated and incorporated into another booklet, leading to mismatched visa pages and covers.
Innovation Solution
A security element comprising multiple partial elements with distinct information that can be moved into a verification position to form authenticity information, allowing for easy verification of correct carrier part assignment, with the option of additional elements providing further authenticity information through overlapping and complementary partial information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the data page is cut out and incorporated into another passport booklet, then the data page can be reused or forged, but the visa pages and cover no longer match the data page, creating a verification problem
Solution Approach 1:
The security element is divided into multiple partial elements (first partial element with first partial information, second partial element with second partial information, and third partial element with third partial information) that are distributed across different carrier parts. Each partial element contains a portion of the authenticity information, and only when all carrier parts are correctly assembled do the partial elements align to reveal the complete authenticity information. This segmentation prevents forgery because manipulating just one carrier part cannot produce the complete authentic security element.
2Reliability
If traditional security features are used, then verification of carrier part assignment is possible, but the verification process is complex and time-consuming
Solution Approach 1:
The patent combines multiple verification functions into a single integrated security element that can be verified through one simple alignment action. The first, second, and third partial elements are positioned such that when the carrier parts are correctly assembled, all partial elements automatically align at the same location to display the complete authenticity information. This merging of multiple security features into one verifiable element simplifies the verification process while maintaining high reliability.
Solution Approach 2:
The authenticity information is pre-divided into partial information segments that are embedded in the respective carrier parts during manufacturing. The partial elements are positioned and oriented in advance so that correct assembly automatically brings them into alignment without requiring additional verification steps. This preliminary arrangement of the security elements eliminates the need for complex verification procedures during inspection.
3Reliability
If multiple security features are added to prevent forgery, then security against manipulation is improved, but the structure becomes more complex
Solution Approach 1:
The security element serves multiple functions simultaneously: it provides authenticity verification, detects carrier part manipulation, and ensures correct assembly of passport components. The same partial elements that verify authenticity also indicate whether the carrier parts are correctly assigned. This multi-functionality is achieved through the intelligent design of the partial information segments, which are positioned to serve both verification and assembly guidance purposes, thereby avoiding additional structural complexity.

AI summary
The invention relates to a security element (1) with authentication information (2) for checking the correct combination of two support parts (3, 4, 5), characterized in that the security element (1) comprises at least one first partial element (6) comprising first partial information (7) and a second partial element (8) comprising second partial information (9). The first partial element (6) can be associated with a first support part (3) and the second partial element (8) can be associated with a second support part (4), both partial elements (6, 8) can be moved from a starting position into a checking position in which both partial elements (6, 8) overlap. The first partial information (7) and the second partial information (9) represent the authentication information (2) when in the checking position.
