Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for uniquely characterizing physical works of art, such as paintings, are prone to counterfeiting and do not ensure the authenticity of the work over time due to variations in digitization processes and physical alterations, and lack robust identification methods.
Innovation Solution
A method involving the application of a substrate containing randomly dispersed micro-RFID transponders within a work of art, which are detected using an RFID system to generate a unique digital fingerprint, processed into a hash, and stored in a blockchain for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digitization processes are used to characterize physical works of art, then identification speed and ease of operation are improved, but measurement precision and reliability deteriorate due to variations in digitization and physical alterations
Solution Approach 1:
The work of art is divided into multiple segments, each containing micro-RFID transponders with unique identification codes. Instead of relying on a single digitized representation, the system segments the authentication into multiple independent RFID tags distributed throughout the artwork, where each tag contributes to the overall digital fingerprint.
Solution Approach 2:
Micro-RFID transponders are introduced as intermediary elements embedded within the artwork substrate. These transponders serve as a mediator between the physical artwork and its digital representation, providing a reliable bridge that connects the physical object to its authenticated digital identity without direct physical contact during verification.
2Device complexity
If traditional identification methods are used, then device complexity is reduced, but reliability and security against counterfeiting worsen
Solution Approach 1:
The identification system uses a composite approach combining multiple RFID transponders with unique codes embedded in the artwork substrate. This composite structure integrates several identification elements that work together to create a robust authentication system, where the combination of multiple coded transponders provides security against counterfeiting while maintaining reasonable system simplicity.
Solution Approach 2:
The RFID transponders with unique identification codes are embedded in the artwork substrate during the creation or early stages of the artwork, before any potential counterfeiting can occur. This preliminary action ensures that the authenticating elements are already in place and cannot be added later by counterfeiters, providing inherent security from the outset.
3Measurement precision
If physical contact methods are used to verify artworks, then measurement precision is improved, but the artwork may be damaged and ease of operation worsens
Solution Approach 1:
The system replaces mechanical contact-based verification methods with electromagnetic field-based RFID detection. Instead of physically touching or closely examining the artwork, the verification system uses electromagnetic fields to communicate with the embedded RFID transponders, eliminating the need for physical contact while maintaining verification accuracy and improving operational convenience.
4Reliability
If multiple transponders are dispersed in the substrate, then reliability and uniqueness are improved, but device complexity and manufacturing complexity increase
Solution Approach 1:
The system changes the parameter of transponder quantity from a single identifier to multiple distributed identifiers. By incorporating multiple micro-RFID transponders with unique codes throughout the substrate, the system achieves higher reliability and uniqueness. The reading system is designed to detect and process signals from multiple transponders, creating a composite digital fingerprint that is more robust and harder to replicate than a single identifier.

AI summary
A method for univocal characterization of a handwork, optionally the handwork being a work of art, provides application of a substrate or paint containing transponders dispersed therein. A detection system reads identifiers of the transponders detectable in position and measures among parameters selected from RSSI, reading speed, response time, distance and/or proximity from/to neighboring transponders. A pattern consisting of or based on characterization information is stored as a reference pattern or identification pattern of the handwork. A recognition scan is carried out by acquiring the same parameters on a portion of the handwork. The pattern of the parameters in the recognition scan is compared with the reference pattern to determine authenticity of copy of the handwork.
