Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized databases are inefficient for secure and precise data sharing among multiple clients, as they lack decentralized solutions for secure data access and management.
Innovation Solution
A decentralized system using a blockchain-based approach, where multiple nodes communicate to share data securely through a distributed ledger, utilizing smart contracts and consensus protocols for secure and precise data sharing among multiple clients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized database is used for data storage and sharing, then data management and control are easy, but data sharing efficiency and security among multiple clients are poor
Solution Approach 1:
The patent divides the centralized database into multiple distributed nodes across a blockchain network. Each node maintains a copy of the ledger, eliminating the single-point bottleneck while enabling parallel data access and sharing operations across multiple clients simultaneously.
Solution Approach 2:
The patent introduces smart contracts as intermediary automated protocols that mediate data access requests between clients. These self-executing contracts enforce access policies, validate requests, and manage data sharing permissions without requiring manual intervention, thereby improving both efficiency and security.
2Quantity of substance
If a centralized database is used for data storage, then data redundancy is minimized, but secure data sharing among multiple services is inefficient
Solution Approach 1:
The patent creates replicated copies of the data ledger across multiple distributed nodes in the blockchain network. Each node holds an identical copy, ensuring data availability and redundancy while maintaining consistency through consensus mechanisms. This enables reliable secure sharing among multiple services without excessive redundancy.
3Reliability
If decentralized data sharing is implemented, then data accessibility and security are improved, but system complexity increases
Solution Approach 1:
The patent implements a universal blockchain infrastructure that handles multiple functions including data storage, access control, authentication, and transaction management within a single integrated system. This multi-functional platform reduces the need for separate systems and simplifies the overall architecture despite the decentralized nature.
Solution Approach 2:
The patent employs smart contracts that automatically execute data access policies and authentication procedures without requiring manual intervention or complex centralized coordination. The system self-regulates through automated consensus mechanisms, reducing operational complexity while maintaining high security and accessibility standards.
Data Source
AI summary
An example operation may include one or more of authenticating, by a first service node, to a first client node, receiving, by the first service node, a data access request from the first client node, comprising request parameters and a request token, generating, by the first service node, a receipt key corresponding to the data access request, and sharing data with a second client node based on the request token and the receipt key.
