Biometric ID Lens Arrangement for Forgery Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current identification documents lack sufficient forgery resistance and longevity, particularly in maintaining the recognizability of biometric image information, which can be manipulated or imitated, and are vulnerable to morphing attacks.
Innovation Solution
The integration of a base image and a derivative image, combined with a lens arrangement, creates a vivid three-dimensional effect, enhancing the recognition of geometric relationships and forms, and incorporating additional security features to prevent manipulation and imitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single flat biometric image is used in identification documents, then the document is easy to produce and view, but the forgery resistance and longevity are insufficient
Solution Approach 1:
The patent transitions from a two-dimensional flat image to a three-dimensional structured image by incorporating relief features and varying depths. The biometric image is created with raised or recessed areas that provide tactile and visual depth, making forgery more difficult while maintaining visual clarity for identification purposes.
Solution Approach 2:
The biometric image is divided into multiple layers or zones with different relief characteristics. Certain critical features (eyes, nose, mouth) are emphasized with greater relief or different textural properties than background areas, creating a segmented structure that enhances both security and recognition.
2Measurement precision
If light and dark highlighting is used to emphasize biometric features, then recognition is improved, but the three-dimensional overall impression and geometric relationship recognizability are insufficient
Solution Approach 1:
The patent adds a third dimension (depth/relief) to the biometric image to enhance geometric relationship recognizability. By creating physically raised or recessed features, the image provides true three-dimensional spatial information rather than relying solely on two-dimensional light and dark variations, enabling better perception of facial geometry and form.
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
This approach significantly increases forgery resistance and longevity by providing a stable and recognizable biometric image, making it difficult to imitate and manipulate, while being cost-effective without requiring new equipment or materials.
Implementation Method 1
at a first certain viewing angle α1 a first image impression is determined by the base image 15 and at a second certain viewing angle α2 a second image impression is determined by the derivative image 16

AI summary
An identification document (1) with a personalization region (3) for receiving biometric image information (5) is proposed. The personalization region (3) comprises a recording layer (11) for image information as well as a lens arrangement (20). Viewing the biometric image information (5) is effected through the lens arrangement (20). The biometric image information (5) holds basic information (12) consisting of a base image (15) and a derivative image (16) derived from the base image (15). The derivative image (16) shows or emphasizes a constituent of the base image (15) that is essential for recognition. At a first viewing angle (α1) the base image (15) is dominantly recognizable, at a second viewing angle (α1) the derivative image (16), so that in the perception of the image information combined from base image (15) and derivative image (16) a plastic overall impression arises.
