Security Hinge Data Page for Biometric Passports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in creating a secure connection for data pages in book-shaped security documents, particularly those with biometric chips, as traditional sewing methods fail due to the thickness and material properties of the plastic used, and there is a high risk of forgery and counterfeiting.
Innovation Solution
A data page design featuring a data section with a fastening area and a hinge section, where the fastening area has a gradation that accommodates the hinge section, incorporating security features like cavities and RFID elements, and using thermally deformable materials for a secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional sewing methods are used to connect data pages, then the connection is durable and secure, but the thick plastic material with biometric chips cannot be easily sewn due to material properties and great thickness
Solution Approach 1:
The data page is divided into a data section and a hinge section with different thicknesses. The hinge section is thinner and more flexible, allowing it to be connected with traditional sewing methods, while the data section maintains the required thickness for biometric chips.
Solution Approach 2:
Different sections of the data page have different local properties: the hinge section is made thinner and more flexible for sewing, while the data section maintains standard thickness for chip accommodation. This local differentiation resolves the contradiction between sewability and chip accommodation.
2Strength
If hinges are thermally joined to the fastening area, then a material bond is created that cannot be separated without damage, but this thermal process adds complexity to the manufacturing process
Solution Approach 1:
The hinge section is thermally joined to the fastening area by heating the hinge section to its melting point, causing it to transition from solid to liquid phase and bond with the fastening area. This phase transition creates a strong material bond that integrates the hinge permanently into the data page.
3Reliability
If security features are incorporated into the fastening area between the hinge section and data section, then forgery protection is enhanced, but the production process becomes more complex
Solution Approach 1:
The security feature is integrated into the fastening area during the initial manufacturing process, before the hinge section is attached. This preliminary incorporation of security features ensures they are built-in and cannot be added later, enhancing forgery protection while streamlining the overall production process.
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 security against forgery by providing a durable and detectable connection that is difficult to replicate, with visible and hidden security features that verify authenticity, and ensures long-lasting attachment.
Implementation Method 1
Thermal joining creates a material bond between the hinge section 20 and the fastening area 12
