Dynamic Optical Security Element Verification via Digital Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for authenticating objects prone to counterfeiting, such as documents and products, are inadequate in ensuring the authenticity of optically variable security elements, which change with orientation and movement, as they often rely on manual comparison and lack real-time updates and flexibility.
Innovation Solution
A control device equipped with a display screen, position and movement sensors, and communication means to generate and display a simulation of the nominal security element, allowing for dynamic comparison with the actual element, ensuring authenticity verification through synchronized movements and orientations, with the ability to access updates via a secure server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual comparison methods are used for authenticating security elements, then the process is simple to operate, but the reliability and accuracy of authentication is insufficient
Solution Approach 1:
The patent creates a digital simulation copy of the nominal security element that reproduces its optical effects. This simulation is displayed on a screen and can be manipulated to match various orientations and movements, allowing controllers to compare the actual security element against the simulated reference without needing physical reference elements or complex manual comparison procedures.
Solution Approach 2:
The patent replaces the mechanical system of physical reference elements and manual comparison with a digital system. The simulation is generated and displayed electronically, and controllers interact with it through a graphical interface, substituting physical manipulation with digital control and comparison.
2Adaptability or versatility
If physical nominal security elements are distributed to controllers for comparison, then the comparison can be performed with real reference, but the system cannot be updated and new security elements cannot be added
Solution Approach 1:
The patent implements a dynamic system where the simulation of the nominal security element can be updated and modified remotely. The simulation is not static like a physical reference element but can be regenerated and redistributed to controllers as needed, allowing the system to adapt to new security elements while maintaining digital reference accuracy.
Solution Approach 2:
The digital simulation serves multiple functions: it acts as a reference for comparison, can be updated to represent new security elements, and can be distributed to multiple controllers simultaneously. This universal digital reference replaces the need for multiple physical reference elements.
3Productivity
If controllers use physical reference elements for comparison, then the optical properties can be directly observed, but the process is time-consuming and not flexible
Solution Approach 1:
The patent creates a digital simulation copy of the nominal security element that reproduces its optical effects. This simulation is displayed on a screen and can be manipulated to match various orientations and movements, allowing controllers to compare the actual security element against the simulated reference without needing physical reference elements or complex manual comparison procedures.
4Reliability
If the security element is made difficult to remove from the document, then counterfeiting is prevented, but the element cannot be transferred for authentication purposes
Solution Approach 1:
The patent creates a digital simulation copy of the nominal security element that reproduces its optical effects. This simulation is displayed on a screen and can be manipulated to match various orientations and movements, allowing controllers to compare the actual security element against the simulated reference without needing physical reference elements or complex manual comparison procedures.
