Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for uniquely characterizing high-value objects like works of art are susceptible to counterfeiting and do not ensure the authenticity of the physical work over time, especially when associating digital NFTs with physical artworks.
Innovation Solution
A method involving the application of a substrate containing randomly dispersed micro-RFID transponders in a paint or resin, which creates a unique digital fingerprint detectable via radio frequency signals, allowing for a stable and immutable association with the artwork's identity, stored as an NFT.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional characterization methods are used for high-value objects, then the process is simple and inexpensive, but the methods are susceptible to counterfeiting and do not ensure authenticity over time
Solution Approach 1:
The system divides the characterization into multiple independent components: micro-RFID transponders embedded in the artwork substrate, optical sensors for detection, and blockchain for data storage. Each component performs a specific function, and together they create a robust authentication system that is resistant to counterfeiting while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The invention uses a composite substrate incorporating both optical materials (for paint or resin application) and electronic components (micro-RFID transponders). This composite structure integrates physical and digital identification layers, creating a multi-factor authentication system that combines material properties with embedded electronics to ensure both reliability and traceability.
2Stability of the object's composition
If micro-RFID transponders are embedded in the substrate, then the digital fingerprint becomes stable and immutable, but the application process becomes more complex
Solution Approach 1:
The micro-RFID transponders are embedded in the substrate during the initial manufacturing or creation phase of the artwork, rather than being added later. This preliminary integration ensures that the transponders become an intrinsic part of the substrate structure, guaranteeing stable positioning and immutable association with the artwork from its inception, while avoiding complex retrofitting processes.
3Reliability
If random dispersion of transponders is used, then the digital fingerprint becomes unique and uncopyable, but the detection process becomes more difficult
Solution Approach 1:
The system incorporates feedback mechanisms where the detection device queries the embedded transponders and receives responses that confirm their presence and positions. The random dispersion pattern itself becomes part of the unique identifier, and the feedback loop validates this pattern during detection, transforming the detection challenge into a verification process that confirms uniqueness rather than complicating it.

AI summary
The present invention relates to the univocal characterization of a handwork (100), such as a work of art, for example, through the application of a substrate or paint containing a certain number of micro transponders (110) dispersed therein. A detection system (130) reads (220) the identifiers of said transponders (110) detectable in said position and measures one or more of the following parameters for each transponder: RSSI, reading speed, response time of each transponder, its position, the distance and/ or proximity from/to neighboring transponders. A pattern consisting of or based on said information is stored (230) as a reference pattern or identification pattern of the handwork (100). A recognition scan (240) can be carried out by acquiring the same parameters on a portion of the handwork. The pattern of such parameters in the reference scan can be compared (250,260) with the reference one, in order to determine whether it is the original handwork (280) or a copy (270).
