Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized data storage systems for user evaluations in online systems face security risks such as data leakage and malicious tampering, as they rely on server protective measures which are not foolproof.
Innovation Solution
A data storage method utilizing a blockchain node deployed in both a user blockchain network and an object blockchain network, where target evaluation data is stored separately in both networks, ensuring secure and consistent data storage through cryptographic guarantees and cross-verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If centralized storage on online system server is used, then data storage simplicity is maintained, but data security deteriorates due to risks of data leakage and malicious tampering
Solution Approach 1:
The patent divides the centralized storage system into multiple distributed blockchain nodes, each maintaining a copy of the evaluation data. This segmentation eliminates the single point of failure in centralized storage while distributing security responsibilities across multiple nodes, thereby improving both security and reliability without significantly increasing operational complexity for end users.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer between users and the storage system. This intermediary provides cryptographic verification, consensus mechanisms, and immutable ledgers that enhance data security and prevent tampering, while abstracting the complexity of distributed storage from end users through standardized interfaces.
2Reliability
If blockchain technology is implemented for secure storage, then data security is improved through tamper-proof mechanisms, but system complexity increases due to distributed network requirements
Solution Approach 1:
The patent designs the blockchain node to perform multiple functions: storing evaluation data, verifying data integrity through cryptographic proofs, maintaining consensus with other nodes, and providing tamper-evident storage. This multi-functionality consolidates security operations into a unified system that, while complex, provides comprehensive protection without requiring separate specialized systems for each security function.
