Dynamic Anti-Forgery Information Using Randomized Encrypted Fields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-forgery technologies, such as static security labels, are easily deciphered and provide inadequate protection against forgery due to their fixed nature.
Innovation Solution
A method involving classification of product information into numeric and text fields, encoding the text field, generating a field with a random number, encrypting it to create an initial anti-forgery field, and dynamically generating target anti-forgery information using symmetric or asymmetric encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If static security labels are used for anti-forgery protection, then the implementation is simple, but the protection effectiveness deteriorates due to ease of deciphering
Solution Approach 1:
The patent transforms static security labels into dynamic anti-forgery information by incorporating random numbers and encryption algorithms. The anti-forgery information changes with each verification process, making it impossible to decipher or reuse, thus resolving the contradiction between simple implementation and effective protection.
Solution Approach 2:
The patent changes the parameter of security information from fixed static labels to dynamic encrypted data. By using encryption algorithms and random numbers, the anti-forgery information undergoes parameter transformation that prevents deciphering while maintaining verification functionality.
2Reliability
If dynamic encryption with random numbers is used, then the anti-forgery protection effectiveness is improved, but the device complexity increases
Solution Approach 1:
The patent introduces an intermediary verification system that coordinates between the product side (containing anti-forgery information) and the verification side (containing decryption capabilities). This intermediary structure enables complex encryption while maintaining manageable system architecture through clear separation of functions.
Solution Approach 2:
The verification system is designed to handle multiple verification requests and can process different types of anti-forgery information using the same encryption framework. This multi-functionality reduces overall system complexity by reusing components across different verification scenarios.
