Problem
Existing seals are prone to counterfeiting and lack the ability to record and verify stamped information, leading to potential disputes and liabilities.
Innovation Solution
An encrypted seal with a graphic text area, seal frame, and bar-shaped digital encryption area, utilizing a changeable encrypted code that records stamped information and employs double encryption by splitting and re-splicing code fragments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional seal textures and anti-counterfeiting fonts are used, then the seal has basic identification function, but it is prone to counterfeiting and cannot record stamped information
Solution Approach 1:
The seal is divided into multiple functional regions: a graphic text area for basic identification, a bar-shaped digital encryption area for cryptographic verification, and a check area for integrity validation. This segmentation allows each region to perform its specific function while collectively providing robust anti-counterfeiting capabilities.
Solution Approach 2:
The patent embeds multiple layers of encryption within the seal structure: the original code is first encrypted to form an encrypted code, then this encrypted code undergoes double encryption through splitting and re-splicing operations. These nested encryption layers are all contained within the compact seal design, providing enhanced security without significantly increasing overall complexity.
2Loss of information
If a bar-shaped digital encryption area with encrypted code is added, then the seal can record and verify stamped information, but the seal structure becomes more complex
Solution Approach 1:
The patent transitions from traditional two-dimensional seal designs to a three-dimensional structured approach by adding vertical layering of encryption functions. The bar-shaped digital encryption area introduces a new dimensional element that accommodates the encrypted code, allowing the seal to store and verify stamped information while maintaining a compact form factor through efficient spatial arrangement.
3Reliability
If double encryption by splitting and re-splicing code fragments is implemented, then security against counterfeiting is enhanced, but the encryption process becomes more complex
Solution Approach 1:
The encryption process is segmented into distinct operational phases: code generation, first encryption, splitting into fragments, re-splicing, and second encryption. Each phase performs a specific transformation that contributes to the overall security, allowing the complex encryption process to be systematically managed and verified.
Solution Approach 2:
The patent performs preliminary encryption operations on the code before it is embedded in the seal. The code is encrypted and split into fragments in advance, and the check area is pre-configured with verification data. This preliminary action ensures that when the seal is stamped, the verification process is streamlined and efficient.
