Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing authentication media with preset reproduction information are vulnerable to counterfeiting, as once the information is known, it can be easily replicated, lacking effective deterrents against tampering and counterfeiting.

Innovation Solution

An authentication medium featuring a laminate structure with personal identification information recorded in one region and check data generated from this information displayed as reconstructed images in a hologram structure in another region, where the hologram structure overlaps with the personal identification information, making it difficult to tamper with the information without corrupting the hologram and thus detectable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If preset reproduction information is displayed on a hologram, then authenticity verification is enabled, but the authentication medium becomes vulnerable to counterfeiting once the information is known

Engineering Contradiction:

Improveauthenticity verificationVSAvoidcounterfeiting vulnerability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the parameter of reproduction information from static/preset to dynamic/generated. The hologram structure generates check data by reading personal identification information and generating check information, then displaying this dynamically generated check data as reconstructed images. This parameter change ensures that the verification information is unique to each authentication medium and cannot be replicated by counterfeiters who do not possess the personal identification information.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces an intermediary processing step between the personal identification information and the hologram display. The hologram structure reads the personal identification information, generates check information through a specific process, and then displays this generated check data. This intermediary generation process acts as a mediator that transforms static personal information into dynamic verification data, preventing direct copying by counterfeiters.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If personal identification information is recorded on the authentication medium, then identification functionality is provided, but tampering detection capability is reduced

Engineering Contradiction:

Improveidentification functionalityVSAvoidtampering detection

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent merges the personal identification information storage function with the hologram verification function. The hologram structure is configured to read the personal identification information recorded on the authentication medium and generate check data based on this information. By combining these functions, the system ensures that any tampering with the personal identification information will be detected during hologram verification, as the check data generation depends on the integrity of the stored information.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a feedback mechanism where the hologram structure reads the personal identification information, generates check information, and displays the check data for verification. This feedback loop allows the system to continuously verify the integrity of the stored personal identification information. When tampering occurs, the check data generation process will produce inconsistent results, providing immediate feedback about the tampering condition.

Inventive Principle:

Principle #23Feedback
