Blockchain Data Processing for Virtual Asset Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing offline audit method for real-right transfers in the context of virtual-asset data is vulnerable to malicious manipulation, leading to insecurity in the transfer process, especially when there is collusion between assessors and applicants, making it difficult to ensure the authenticity and security of service data.
Innovation Solution
A blockchain-based data processing method and apparatus that utilizes smart contracts to create and deploy right detection functions and statements, ensuring only authorized service nodes can access virtual-asset associated data, thereby enhancing data security through immutability and transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If offline audit method is used for real-right transfer, then the process is simple and easy to operate, but the security and authenticity of service data cannot be ensured due to malicious manipulation
Solution Approach 1:
The patent introduces a blockchain-based intermediary system that mediates between service nodes and data. The smart contract acts as an automated intermediary that enforces access control rules, verifying data access rights without human intervention. This intermediary layer ensures data security while maintaining operational simplicity for users.
Solution Approach 2:
The system implements self-service through automated smart contracts that autonomously verify data access rights and enforce security policies. The right detection function automatically identifies authorized service nodes and grants access without manual approval, enabling the system to secure itself while reducing operational complexity.
2Reliability
If blockchain-based right detection function is deployed, then the security and authenticity of virtual-asset data is ensured, but the system complexity increases due to smart contract deployment and management
Solution Approach 1:
The patent applies preliminary action by pre-deploying smart contracts with embedded right detection functions before data access operations occur. The access control logic is prepared in advance within the smart contract, so when data access is requested, the verification process is already in place and ready to execute automatically, reducing the perceived complexity for end users.
Solution Approach 2:
The smart contract serves multiple functions: it stores data, verifies access rights, executes right detection, and manages service node authentication. By consolidating these functions into a single multi-functional smart contract, the system reduces overall complexity compared to having separate components for each function.

AI summary
A block chain-based data processing method and apparatus, a device, and a readable storage medium are provided in implementations of the disclosure. The method includes the following. A real-right transfer request sent by a first service node is obtained. A smart contract is triggered and a set of second service nodes is obtained according to the real-right transfer request. A right detection function name and a right detection statement are created according to the set of second service nodes and a data access right for virtual-asset associated data. Upon obtaining a data access request for the virtual-asset associated data from a first target service node, a data access right of the first target service node is detected through the right detection statement corresponding to the right detection function name. Upon detecting that the first target service node has the data access right for the virtual-asset associated data, the virtual-asset associated data is returned to the first target service node. As such, with the disclosure, the security of service data can be ensured, and the security in transferring real right of an item can be improved.
