Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data management systems face challenges in securely storing and accessing data across a distributed environment while ensuring data integrity and access control, particularly in scenarios involving multiple users and entities with varying access rights.
Innovation Solution
A data manager system utilizing persistent storage and distributed data structures like blockchains to store identity chains and data availability chains, enabling secure data storage and access management through public and private keys, and smart contracts for conditional data access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored with predetermined access controls, then data security is improved, but data accessibility deteriorates
Solution Approach 1:
The patent segments access control into multiple layers: data owners retain ownership rights, data managers control storage and basic access, and smart contracts enforce conditional access rules. This segmentation allows different entities to have different levels of access without compromising overall security, resolving the contradiction between security and accessibility.
Solution Approach 2:
The patent introduces smart contracts as intermediaries between data owners, data managers, and data consumers. These smart contracts automatically enforce access conditions and permissions, enabling secure yet accessible data sharing without requiring predetermined manual access controls. The intermediary mechanism facilitates flexible access while maintaining security through automated verification.
2Ease of operation
If data is stored in a distributed environment, then data accessibility is improved, but data integrity deteriorates
Solution Approach 1:
The patent implements feedback mechanisms through smart contracts that continuously verify data integrity in the distributed environment. The system monitors data access, modification, and storage operations, automatically enforcing integrity rules and providing feedback to all participants. This continuous verification ensures data integrity is maintained across the distributed network while preserving accessibility.
Solution Approach 2:
The patent changes the parameters of data storage by using cryptographic hashing and digital signatures to transform data into verified forms. Data integrity is ensured through parameter changes such as generating hash values for verification and using digital signatures to authenticate data origin and modification status, allowing distributed storage with maintained integrity.
3Reliability
If access control is implemented for data, then data security is improved, but system complexity deteriorates
Solution Approach 1:
The patent creates a universal access control framework using smart contracts that can handle multiple data types, access scenarios, and permission levels through a single standardized mechanism. This multi-functional approach reduces system complexity by providing a unified access control interface that works across different contexts, eliminating the need for separate complex access control systems for each data type or scenario.
Data Source
AI summary
A data manager includes persistent storage and a data register. The persistent storage stores an identity chain and a data availability chain. The data register obtains data associated with an entity registered with the identity chain using a public key associated with the entity; obtains an object identifier associated with the data by storing the data in a data storage as a record; and records, on the data availability chain, both of: the record using a private key associated with the entity, and the object identifier.
