Security Seal Using Shredded Banknote Snippets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for securing documents and products against counterfeiting are inadequate, as they can be easily replicated or imitated using accessible technologies, and existing security features can be removed or reused, failing to provide robust protection against forgery.
Innovation Solution
A method involving a security seal created using shredded banknote snippets with high-tech security features, arranged randomly on a carrier layer, which is then applied to an original object, providing a unique and irreproducible authentication mechanism that integrates additional forgery-proof features like holograms and codes, ensuring the seal is inseparable and tamper-proof.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional security seals (embossing stamps, sealing wax, holograms) are used, then the authentication process is simple and accessible, but the security against counterfeiting is insufficient as these can be easily replicated
Solution Approach 1:
The security seal is segmented into multiple independent layers: a carrier layer with randomly arranged banknote shreds, a hologram layer with micro-relief structures, and a protective coating. Each layer contributes unique security features that are difficult to replicate individually, and their combination creates a multi-layered authentication system that significantly increases counterfeiting difficulty while maintaining visual accessibility.
Solution Approach 2:
The invention combines heterogeneous materials with different security properties: shredded banknotes containing embedded security threads and watermarks, holographic foil with micro-relief patterns, and transparent protective coatings. This composite structure integrates multiple authentication mechanisms into a single seal, providing robust counterfeiting protection while preserving ease of visual verification.
2Productivity
If security seals are pre-produced using integrated machines and devices, then manufacturing efficiency is high, but security risks increase due to potential manipulation and viewing by third parties
Solution Approach 1:
Security features are prepared in advance but in a dormant state: banknotes are shredded and stored in secure containers, holographic foils are pre-cut into patterns but not yet assembled. The final assembly occurs only at the point of seal application, ensuring that all security elements are already in place before any potential manipulation risk during the actual sealing process.
Solution Approach 2:
The carrier layer acts as an intermediary that holds and protects the shredded banknotes and holographic elements until the moment of application. This intermediate carrier structure allows for secure storage and controlled dispensing of security features, separating the preparation phase from the application phase to minimize exposure to manipulation risks.
3Manufacturing precision
If graphical security features are produced in a precisely defined and reproducible manner, then consistency is achieved, but the security can be reproduced if the pattern is known or understood
Solution Approach 1:
Each security seal possesses unique local characteristics: the specific arrangement, orientation, and selection of individual banknote shreds vary randomly; the holographic pattern is locally customized with unique micro-relief structures. This local variability ensures that while each seal meets precise manufacturing standards, no two seals are identical, preventing reproduction even if one seal's pattern is discovered.
Solution Approach 2:
The security seal incorporates dynamic elements that change with viewing angle and lighting conditions: the holographic foil displays different patterns and colors from various angles, and the embedded security threads in banknote shreds exhibit shifting optical properties. This dynamic behavior creates continuously varying visual characteristics that cannot be statically reproduced.
