Unique Identifier Authentication via Image Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods for high-value and high-volume products/documents require specialized knowledge and tools to verify authenticity, making it difficult for large numbers of people to easily authenticate goods without the need for special knowledge or tools, especially as counterfeit security devices improve in quality.
Innovation Solution
A method and system that generates and captures images of security devices, prints unique identifiers over these images, and stores them in a computer-readable memory, allowing for easy authentication by comparing captured images with previously stored images to determine authenticity based on a similarity threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex anti-counterfeiting security images with unique identification numbers are used, then authentication reliability is improved, but device complexity and difficulty of detection increase
Solution Approach 1:
The patent changes the parameter of authentication from visual inspection of complex security features to numerical comparison of unique identification numbers. This transforms the authentication process from qualitative assessment of security images to quantitative verification of ID numbers, simplifying the device while maintaining reliability
Solution Approach 2:
The patent extracts the essential authentication element (unique identification number) from the complex security device and separates it from the security image. This allows the ID number to be independently verified without requiring specialized equipment to analyze the entire security device, reducing complexity while preserving authentication reliability
2Measurement precision
If specialized knowledge and tools are required for verification, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent creates a database copy of unique identification numbers from authenticated security devices. This allows verification through simple numerical comparison rather than requiring users to possess specialized knowledge for analyzing security features. The copied ID numbers enable precise verification through straightforward data matching, making the process accessible to ordinary users
Solution Approach 2:
The patent replaces the mechanical/visual inspection system with an automated digital comparison system. Instead of requiring users to physically examine security features with specialized tools, the system uses automated optical character recognition and database comparison, substituting complex manual verification with simple automated processing that maintains precision while improving ease of operation
