Decentralized Node Privilege Verification via Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Decentralized multi-node architectures lack effective privilege management mechanisms, leading to risks of malicious data tampering and security breaches.
Innovation Solution
Implement a method where a first node receives a request from a second node for a target operation, obtains the second node's privilege from a third node, determines a threshold privilege based on the operation type, and only performs the operation if the second node's privilege is higher than the threshold, using a Distributed Hash Table system to manage and secure node privileges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a decentralized multi-node architecture is used for data processing, then system efficiency and cloud computing pressure reduction are improved, but data security and privilege management reliability deteriorate
Solution Approach 1:
The patent introduces a third node as an intermediary to manage and verify privileges between nodes. When node A wants to perform an operation on node B's data, the system queries node C (the intermediary) to verify node A's privilege level. This mediator approach maintains the decentralized architecture's efficiency while adding a security layer that prevents unauthorized operations, thus resolving the contradiction between system efficiency and data security.
2Reliability
If privilege verification through a third node is implemented, then data security is improved, but system complexity and operation time increase
Solution Approach 1:
The third node serves multiple functions: it stores privilege information, verifies operation requests, and maintains the privilege database. By making this node universal and multi-functional, the patent reduces overall system complexity compared to having separate dedicated components for each function. The same third node handles different types of privilege verifications and manages various operation types, simplifying the architecture while maintaining security.
3Reliability
If privilege verification through a third node is implemented, then data security is improved, but operation time and processing duration increase
Solution Approach 1:
The system performs preliminary actions by pre-establishing the third node with all necessary privilege information before operations occur. Privilege levels and authorization rules are pre-configured and stored in the third node's database. When an operation request comes in, the verification process is quick because the necessary information is already prepared and stored, rather than computing privileges in real-time during each operation.
Data Source
AI summary
A data management method comprises: receiving, at a first node of a plurality of nodes for collaboratively data processing, a request to perform a target operation at the first node from a second node of the plurality of nodes; obtaining a privilege of the second node from a third node of the plurality of nodes; determining a threshold privilege for performing the target operation based on a type of the target operation; and performing the target operation in accordance with a determination that the privilege of the second node is higher than the threshold privilege. In this manner, the security of data may be improved.
