Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blockchain technologies struggle to effectively map unique digital items to physical real-world items due to the reliance on third-party trust, which undermines their use and lack a robust method for asset provenance and end-to-end tracking.
Innovation Solution
A framework that uses spectral imaging and 3D scanning to generate unique signatures for physical items, combined with peer-to-peer network nodes for authentication, location proof, and a Blockchain Authentication and Trust Module (BATM) to ensure data integrity and trust without relying on third parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical items are mapped to blockchain using traditional methods, then item tracking is enabled, but third-party trust is required which undermines blockchain's decentralized nature
Solution Approach 1:
The physical item itself performs the identification function through its unique physical characteristics (spectral signature, 3D geometry, mass). The item 'identifies' itself by presenting these inherent properties to the scanning device, eliminating the need for embedded RFID tags, QR codes, or other artificial identification mechanisms that would require third-party issuance and management.
Solution Approach 2:
The patent replaces mechanical/electronic identification systems (RFID tags, barcodes, NFC chips) with a physics-based identification system using spectral imaging and 3D scanning. The unique physical properties of the item (molecular vibrations, geometric features) are directly measured and used for identification, substituting complex mechanical identification hardware with optical and geometric analysis.
2Measurement precision
If unique identification methods are implemented for physical items, then item authentication is improved, but the complexity of analysis equipment increases
Solution Approach 1:
The identification system is segmented into two distinct components: a simple scanning device that captures physical properties (spectral data, 3D geometry, mass) and a centralized analysis system that processes this data to generate unique identifiers. This segmentation allows the scanning device to remain relatively simple while the complex analysis and pattern recognition functions are performed by more powerful remote systems.
Solution Approach 2:
Instead of requiring complex analysis equipment at every node, the patent creates a digital copy or representation of the item's physical properties (spectral hypercube, point cloud data, mass measurement) that can be transmitted and analyzed elsewhere. The unique identification is derived from copying the item's inherent physical characteristics rather than requiring complex local analysis capabilities.
3Measurement precision
If comprehensive physical analysis is performed on items, then unique signatures are generated, but the time required for item processing increases
Solution Approach 1:
The system performs preliminary analysis by capturing multiple physical properties (spectral data, 3D geometry, mass) simultaneously during a single scanning operation. The multi-dimensional data collection is prepared in advance, allowing for rapid comparison and matching operations later. The spectral hypercube and point cloud data are pre-processed to extract key features that can be quickly compared against stored records.
Solution Approach 2:
The patent merges multiple measurement modalities (spectral imaging, 3D scanning, mass measurement) into a single integrated identification process. By combining these measurements and creating a unified unique signature from all data sources, the system achieves high identification accuracy without requiring separate processing steps for each property, thereby reducing total processing time.

Implementation Method 1
a spectral imager to assess the spectral hypercube data of the physical item, identifying irregularities in composition of the physical item, notably the radiometric measurements at various spatial frequencies
Implementation Method 2
a light source (e.g. Xenon based) to provide broad spectrum illumination on the physical item
Implementation Method 3
a range scanner (e.g. laser based) to assess the 3D spatial data of the object

AI summary
There is provided a framework to record to a blockchain unique identification (signatures) of physical items which have unique, random properties. Physical items are analysed using spectral imaging to determine the unique identifications. Hardware is shown to perform the analysis and various nodes of a peer-to-peer network are shown and described, which nodes may be configured to provide proof of location, privacy, trust and authentication. The solution can work even if the item is modified in some way if a subset of the unique properties remain.
