Blockchain Vehicle Data Privacy via Segmentation and Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-related information processing systems based on blockchain do not adequately protect the privacy and security of vehicle owners, as they allow unauthorized access and transmission of personal and property-related information.
Innovation Solution
A method and apparatus that utilize blockchain technology to embed user identifiers into vehicle-related information, ensuring only the information owner can transmit or access their data, thereby restricting unauthorized transactions and protecting personal and property safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle-related information is stored and transacted on blockchain to ensure transparency and traceability, then transaction reliability is improved, but vehicle owners' privacy and security are compromised
Solution Approach 1:
The patent segments vehicle-related information into two categories: public information (vehicle basic info, transaction records) and private information (owner personal info, contact details). Only public information is stored on the blockchain, while private information is stored off-chain in encrypted form. This segmentation allows maintaining transaction transparency without exposing sensitive personal data to the entire network.
Solution Approach 2:
The patent introduces a privacy protection layer as an intermediary between the blockchain and the data storage system. This intermediary uses encryption technology and access control mechanisms to filter and protect private information, allowing the blockchain to maintain its transparency function while preventing direct exposure of sensitive data.
2Extent of automation
If blockchain technology is used to enable decentralized vehicle information transactions, then system autonomy is improved, but unauthorized access to personal information increases
Solution Approach 1:
The patent applies different access control policies to different data types. Public vehicle information is accessible to all network participants, while private owner information has restricted access limited to authorized users only. This local quality differentiation allows the system to maintain autonomy for public transactions while preventing unauthorized access to private data.
Solution Approach 2:
The patent implements preliminary authentication and authorization actions before allowing any access to vehicle information. Users must undergo identity verification and obtain access permissions before they can query or transaction private information. This preliminary action prevents unauthorized access attempts before they can occur.
3Loss of information
If vehicle information is made accessible on blockchain for market transactions, then information availability is improved, but personal safety risks increase
Solution Approach 1:
The patent extracts private personal information from the blockchain storage and transfers it to encrypted off-chain storage. Only essential public vehicle information remains on the blockchain for market transactions. This extraction eliminates the risk of personal safety threats while preserving the availability of necessary transaction information.

AI summary
Embodiments of the present disclosure discloses a method and an apparatus for processing vehicle-related information based on blockchain, and a computer device and a computer readable storage medium, which are used for prohibiting or restricting others other than the information owner from using the blockchain network to trade and spread privacy information of the information owner. The method according to an embodiment of the present disclosure includes: a node of a blockchain network may obtain vehicle-related information of a user, embed an identifier of the belonged user into the vehicle-related information of the user, deposit the vehicle-related information embedded with the identifier of the belonged user in a blockchain as a transaction object based on the blockchain network. When the transaction on the vehicle-related information embedded with the identifier of the belonged user is detected, whether the seller of the transaction is the user corresponding to the embedded belonged identifier, if it is not continuation of the transaction is prohibited or restricted.
