GeoBlockchain Map Authentication for Tamper-Proof Geospatial Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing GIS systems lack a viable implementation of blockchain technology to provide secure, tamper-proof, and transparent management of geospatial data, particularly in applications like real estate and supply chain transactions, which require location-specific and immutable record-keeping.
Innovation Solution
The integration of blockchain with GIS systems, known as GeoBlockchain, enables secure, tamper-proof, and transparent management of geospatial data by encoding geographic features and transaction data into blocks, using a permissioned blockchain with spatial smart contracts to validate and visualize transactions on a map.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain technology is integrated with GIS systems to provide secure and tamper-proof management of geospatial data, then data security and immutability are improved, but system complexity increases
Solution Approach 1:
The patent combines blockchain technology with GIS systems to create GeoBlockchain, merging the security and immutability features of blockchain with the geospatial data management capabilities of GIS. This integration allows geospatial data to be stored and managed on the blockchain, providing secure and tamper-proof management while maintaining the functionality of the GIS system.
Solution Approach 2:
The patent segments the GIS system into modular components that can interact with the blockchain. By dividing the system into distinct functional modules, the complexity of integrating blockchain is reduced, and each module can be developed and maintained independently, thereby managing system complexity while achieving secure data management.
2Reliability
If geographic features and transaction data are encoded into blockchain blocks for immutable record-keeping, then data integrity and transparency are improved, but data processing time increases
Solution Approach 1:
The patent performs preliminary encoding of geographic features and transaction data into standardized formats before they are written to the blockchain. By preparing and validating data in advance, the actual blockchain writing process is accelerated, reducing the overall data processing time while maintaining data integrity and immutability.
3Reliability
If permissioned blockchain with spatial smart contracts is used to validate transactions, then transaction security and authenticity are improved, but computational requirements and energy consumption increase
Solution Approach 1:
The patent introduces spatial smart contracts as intermediaries that automatically validate geospatial transactions based on pre-defined rules and conditions. These smart contracts act as mediators between transacting parties, eliminating the need for complex manual verification processes and reducing the overall computational burden while maintaining high transaction security and authenticity through automated consensus mechanisms.
Data Source
AI summary
A method of providing a map with imbedded, authenticated data is described. A geographic feature is represented on a map with one or more of points, lines and polygons in a first layer of the map. Data corresponding to the geographic feature is provided. The provided data is encoded, in a first block, with the one or more of points, lines and polygons from the first layer of the map. The block is combined with other blocks of a blockchain. The blockchain is associated with the geographic feature on the map as represented by the one or more of points, lines and polygons in the first layer of the map.
