Blockchain Logistics Tracking with Encrypted Ownership Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain-based logistics systems fail to ensure privacy of logistics information, allowing third parties to access product authenticity tracking, which limits end consumers' ability to verify product authenticity directly.
Innovation Solution
A blockchain-based logistics management method that uses encrypted ownership information and zero-knowledge proof algorithms to secure transaction data, allowing consumers to decrypt and verify ownership information while maintaining privacy, enabling them to track the logistics movement path and confirm product authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a public blockchain is used for logistics tracking, then transparency and accessibility of logistics information is improved, but privacy of logistics information deteriorates as third parties can access sensitive data
Solution Approach 1:
The patent segments information into two categories: logistics movement path information (public) and ownership information (private). This segmentation allows different parts of the logistics data to have different access permissions, enabling consumers to track products while protecting sensitive ownership details from unauthorized access.
Solution Approach 2:
The patent introduces an intermediary verification mechanism where the blockchain network verifies the authenticity and ownership status of products without exposing detailed ownership information to the public. This intermediary role allows transparency in tracking while maintaining privacy through cryptographic verification.
2Object-affected harmful factors
If a closed or permissioned blockchain is used for logistics management, then privacy of logistics information is improved, but accessibility and direct verification capability for end consumers deteriorates
Solution Approach 1:
The patent segments information access rights so that consumers can access logistics movement path information freely while restricted access is maintained for detailed ownership information. This selective accessibility enables consumer verification without requiring complex permission management.
Solution Approach 2:
The patent creates a public copy of essential tracking information (logistics movement path) that consumers can access freely, while the original detailed ownership information remains private. This copying approach enables verification capability without exposing sensitive data.
3Reliability
If all logistics information is made publicly accessible on blockchain, then product authenticity verification is improved, but information security and commercial sensitivity deteriorates
Solution Approach 1:
The patent segments information into authenticity verification data (public) and sensitive ownership data (private). The logistics movement path and product identification information are made public for verification, while detailed ownership information remains private, enabling authenticity verification without compromising information security.
Solution Approach 2:
The patent applies different quality levels of information disclosure to different parts of the logistics data. Essential verification information is disclosed publicly with high quality, while sensitive ownership information is protected with restricted access, creating local quality variations in information availability.
Data Source
AI summary
Disclosed is a logistics management method and apparatus using a blockchain, in which a logistics movement path can be tracked while privacy for logistics information is ensured. The disclosed logistics management method using a blockchain includes generating first transaction information for registration of a target unit including at least one child unit, transmitting the first transaction information to a blockchain network, generating second transaction information according to transfer of ownership of the target unit, and transmitting the second transaction information to the blockchain network.
