Distributed Ledger Task Management via Segmented Blockchain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public blockchain networks lack control over who can access data and when, as well as limitations on where data can be accessed, leading to potential security issues.
Innovation Solution
A distributed-ledger network that uses ad-hoc routing and blockchain technology to manage permissions and access control, allowing for secure and controlled data sharing by defining routing conditions and using cryptographic validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If public blockchain networks allow anyone to access data, then data availability is improved, but data security and privacy deteriorate
Solution Approach 1:
The patent segments the blockchain network into public and private components. Public blocks contain only transaction hashes and metadata, while private blocks contain sensitive data that is encrypted and accessible only to authorized participants. This segmentation allows the system to maintain public accessibility for transaction verification while protecting sensitive data from unauthorized access.
Solution Approach 2:
The patent introduces encrypted data structures and authorization mechanisms as intermediaries between the public blockchain and private data. These intermediaries enable public nodes to verify transaction validity without exposing sensitive information, thus maintaining data security while preserving public accessibility.
2Stability of the object's composition
If blockchain blocks are immutable and permanent, then transaction history integrity is improved, but access control and time limitations deteriorate
Solution Approach 1:
The patent applies different quality characteristics to different parts of the blockchain structure. Public blocks maintain immutability and permanence for integrity, while private blocks incorporate encryption and time-limited access controls. This allows the system to preserve transaction history integrity in public blocks while enabling access control and time limitations in private blocks where sensitive data is stored.
Solution Approach 2:
The patent implements preliminary encryption and authorization setup before data is written to the blockchain. By pre-configuring access controls, time limits, and encryption keys, the system ensures that even though blocks are immutable, access to sensitive information can be restricted and time-limited without compromising the permanent transaction history.
3Reliability
If routing conditions and cryptographic validation are implemented, then data security is improved, but system complexity and processing time worsen
Solution Approach 1:
The patent implements routing conditions and cryptographic validation selectively rather than universally. Only transactions involving private blocks or sensitive data undergo extensive validation, while public transactions use simplified verification. This partial application of security measures maintains data security for critical operations while reducing overall system complexity and processing overhead.
Data Source
AI summary
A distributed ledger-based system, method and apparatus for managing tasks. An authorization record proposal is validated by a localized blockchain authorization network against a validated schema published by, in some cases, a core blockchain network. Once validated, it is published on a localized channel for use by other nodes to validate actions of the task as the task is being performed. Data relating to completed tasks may be shared in accordance with sharing information in the validated authorization record and the data may be deleted upon the occurrence of a predetermined condition.
