Solution Overview

Problem

Current security and value documents with RFID functionality lack adequate protection against unauthorized data reading, and existing display methods are inefficient in terms of data storage and verification security.

Innovation Solution

A value or security document with an electronic display device that shows an image sequence of the owner from different views, controlled by an electronic circuit, which can be activated and navigated using a user interface, and powered through a contactless energy interface, allowing for secure visual and machine verification with reduced data storage requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single two-dimensional image is displayed on the display device, then the data storage requirement is minimal, but the security verification reliability is insufficient

Engineering Contradiction:
Improvesecurity verification reliabilityVSAvoiddata storage requirement
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent divides the verification process into multiple sequential images (first image, second image, third image) showing different views of the owner's face. Each image is displayed separately in sequence rather than storing all images simultaneously, reducing data storage requirements while maintaining verification reliability through multi-view assessment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display device dynamically switches between different images in sequence (first image for a certain period, then second image, then third image). This dynamic sequential display allows the system to present multiple verification views over time without requiring all images to be stored and processed simultaneously, optimizing the balance between verification reliability and data storage efficiency.

Inventive Principle:
Principle #15Dynamics

2Reliability

If access control mechanisms are implemented to protect against unauthorized reading, then the security protection is improved, but the device complexity increases

Engineering Contradiction:
Improvesecurity protectionVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary access control checks before allowing any data reading or display operations. The control unit first verifies whether the reading device is authorized to access the document data, and only if authentication succeeds does it proceed to display images or transfer data. This preliminary security check prevents unauthorized access without requiring complex continuous monitoring systems.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control unit acts as an intermediary between the reading device and the stored data/images. It mediates the interaction by first evaluating access rights, then controlling whether images are displayed or data is transferred. This intermediary approach simplifies the overall system architecture by centralizing security management in a single control unit rather than distributing complex security mechanisms throughout the system.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If multiple images from different views are displayed sequentially, then the verification security is enhanced, but the verification time increases

Engineering Contradiction:
Improveverification securityVSAvoidverification time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent displays images in a periodic sequential manner: first image for a certain period of time, then switches to second image for a certain period, then to third image. This periodic display allows verification authorities to review multiple images at their own pace without forcing rapid sequential presentation, balancing thorough verification with acceptable time requirements. The periodic action enables deliberate viewing of each image while maintaining the security benefit of multi-view verification.

Inventive Principle:
Principle #19Periodic action
