See-through Identification Document with Filtering Device for Anti-counterfeiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identification documents with see-through portions can be easily modified or falsified, as the security markings are visible from both sides and can be reproduced or replaced, compromising their security.
Innovation Solution
Incorporating a filtering device on one side of the see-through portion to reveal hidden personalized information only when viewed through that side, while maintaining visibility of the first personalized information from both sides, making it difficult to modify or replace the embedded information without affecting the original.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If security markings are made visible from both sides of the see-through portion, then authentication can be performed from either side, but the security markings can be easily reproduced or replaced by infringers
Solution Approach 1:
The patent divides the security information into two distinct layers: first personalized information visible from both sides for basic authentication, and second hidden personalized information visible only through the filtering device for enhanced security verification. This segmentation allows different authentication levels while preventing complete reproduction by infringers.
Solution Approach 2:
The filtering device acts as an intermediary element that reveals the hidden second personalized information. Without this intermediary filtering device, the second information remains invisible, thus preventing infringers from reproducing it even if they have access to the see-through portion.
2Reliability
If hidden personalized information is inserted into the first personalized information, then modification detection becomes possible, but the hidden information cannot be viewed without the filtering device
Solution Approach 1:
The patent applies different visibility properties to different parts of the personalized information. The first personalized information has the quality of being visible from both sides, while the second hidden personalized information has the quality of being visible only through the filtering device. This local differentiation of visibility properties enables both ease of authentication and security against modification.
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 identification documents by ensuring that hidden personalized information can only be viewed with the filtering device, making it nearly impossible to modify or replace the see-through portion without detection, thus protecting the identity-linked information.
Implementation Method 1
a filtering device is provided on the second side of the see-through portion, in order to reveal the hidden second personalized information, which appears superimposed onto the first personalized information, when viewed from said second side

AI summary
The invention relates to an identification document comprising a see-through portion (10) having a first side (S1) and a second side (S2), said see-through portion comprising first personalized information (11), said identification document being made so that the see-through portion enables to visualize different personalized information from its both sides, in such a manner that it becomes impossible for an infringer either to modify the personalized information or to remove the see-through portion and to replace it by another completely falsified see-through portion. For that, the first personalized information (11) comprises a second personalized information (12), which is hidden into it when viewed from the first side (S1),a filtering device (16) is attached on the second side (S2) of the see-through portion (10), in order to reveal the hidden second personalized information (12), which appears superimposed onto the first personalized information (11) when viewed from said second side (S2), while it remains hidden when viewed from the first side (S1).
