Identity Document with Laser-Engraved Holographic Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current identity documents lack effective security features that are difficult to counterfeit, particularly holographic features, which are prone to being detached from the document during manufacturing, making them vulnerable to counterfeiting.
Innovation Solution
An identification document with multiple layers of security materials, including pre-fabricated reflective or holographic materials, is created using a laser engraver to integrate a unique secure image seamlessly across the layers, making counterfeiting more expensive and time-consuming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If holographic security features are attached to the document base during manufacturing, then security is enhanced, but the features may be detached during manufacturing making them vulnerable to counterfeiting
Solution Approach 1:
The patent merges the holographic security feature with the optical medium by recording the hologram directly into the medium during manufacturing. This integration ensures the security feature becomes an inherent part of the document structure, eliminating detachment risks while maintaining security enhancement.
Solution Approach 2:
The holographic security feature is nested within the optical medium structure itself. The medium is tailored to accommodate holographic recording, creating a nested configuration where the security feature is embedded within the document's fundamental structure rather than being attached externally.
2Manufacturing precision
If a complex optical system is used to record a quality hologram, then hologram quality is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent changes the parameters of the optical medium itself, tailoring the medium to be suitable for holographic recording. By modifying the medium's properties rather than using a complex recording system, the patent achieves high-quality holograms while reducing optical system complexity.
Solution Approach 2:
The patent uses computer-generated holograms recorded on the optical medium. This approach replaces the need for complex optical recording systems with a digital design and direct recording process, maintaining hologram quality while reducing manufacturing complexity.
3Reliability
If holographic features are attached as separate components, then security is improved, but the document structure becomes more complex
Solution Approach 1:
The patent combines the holographic security feature with the optical medium into a single integrated structure. This merger eliminates the need for separate attachment components, reducing document structural complexity while maintaining the security benefits of holographic features.

AI summary
An identification document and method of manufacturing the same is disclosed. Specifically, the identification document includes an image area in which both a base material of the identification document and a security material are present. One or more images are written into the image area such that reliefs are created in both the base material and the security material and also such that the image is a continuous image, even across transitions from the base material and the security material.
