Paper-Based Anti-Counterfeiting Electronic Seal with Visual Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic seal technologies lack paper-based visually identifiable anti-counterfeiting functions, making them vulnerable to forgery and difficult to authenticate, especially in off-line scenarios, which hinders the widespread adoption of online contract signing.
Innovation Solution
The implementation method involves generating a seal pattern with a fixed information unit and a dynamic information unit using electronic seal functional software. The dynamic information unit includes an associated code of authorized counterpart, which is generated through communication tool number information and presented in a directly visually readable form within the seal pattern, enabling easy authentication and verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic seal patterns are created using word processing or graphic software and printed onto paper, then the convenience of electronic seal application is improved, but the anti-counterfeiting capability deteriorates because these imitated seal patterns are easily forged and difficult to authenticate visually
Solution Approach 1:
The patent applies color changes by incorporating variable color elements into the electronic seal pattern that change based on authentication status. The seal pattern includes authentication information that can be visually verified through color differentiation, allowing users to distinguish between authentic and forged seals. This resolves the contradiction by maintaining electronic seal convenience while adding visual anti-counterfeiting capability through color-based authentication indicators.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism that bridges electronic seal convenience and physical anti-counterfeiting needs. The seal pattern includes embedded authentication codes and visual indicators that act as intermediaries between the electronic seal system and the user's visual verification capability. This allows the seal to be applied electronically while providing visual cues for authentication, resolving the contradiction between ease of operation and reliability.
2Ease of manufacture
If simple copies of physical seal patterns are used for electronic seals, then the ease of creating electronic seals is improved, but the visual anti-counterfeiting function deteriorates because the printed patterns are identical and cannot be visually distinguished from forgeries
Solution Approach 1:
The patent applies dynamics by making the electronic seal pattern dynamic rather than static. The seal pattern includes variable elements that change based on authentication status, timestamp, or other parameters. This dynamic characteristic allows the seal to be easily created electronically while providing visual differentiation between authentic and forged seals, resolving the contradiction between ease of manufacture and visual anti-counterfeiting detection.
Solution Approach 2:
The patent changes parameters of the seal pattern such as color, position, or configuration based on authentication status. These parameter changes enable the seal to maintain simplicity in creation while providing visual indicators for anti-counterfeiting verification. The variable parameters allow easy electronic generation while creating detectable visual differences that prevent forgery detection difficulties.
3Reliability
If complicated electronic authenticity verification processes are used, then the anti-counterfeiting reliability is improved, but the ease of operation deteriorates because the verification process is complex and deters beginner users
Solution Approach 1:
The patent enables self-service authentication by incorporating visual indicators directly into the seal pattern that users can verify without complex electronic processes. The seal includes embedded visual cues such as color codes, patterns, or text that allow users to authenticate the seal's validity through simple visual inspection. This resolves the contradiction by maintaining high anti-counterfeiting reliability while eliminating complex verification steps, making the process accessible to beginner users.
Solution Approach 2:
The patent extracts the essential authentication information and presents it in a simplified visual format within the seal pattern itself. Rather than requiring users to navigate complex electronic verification systems, the critical authentication data is extracted and displayed as visual indicators that can be quickly assessed. This maintains anti-counterfeiting reliability while dramatically simplifying the user operation to basic visual verification.

AI summary
An implementation method for a paper-based visually identifiable anti-counterfeiting electronic seal is achieved through functional software that is configured with an authentication communication interface. An electronic seal pattern includes a fixed information part and a dynamic information part, and the later includes an associated code of stamped sample and an associated code of authorized counterpart. An operator needs to provide a communication tool number of an authorized counterpart, serving as an associated code to be embedded into the seal pattern for intuitive display. The software binds the code to stamped samples, permitting the authorized counterpart to authenticate, extract, or consult the samples through a communication tool. Using the authentication communication interface, the authorized counterpart can perform anti-counterfeiting verification on the stamped samples.
