Web3 Data Obfuscation Through Distributed-Ledger Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data stored in Web3 environments is vulnerable to exposure and unauthorized access due to decentralized storage across multiple physical computing devices, with private ledgers susceptible to user errors and public ledgers accessible by the public.
Innovation Solution
Data objects are divided into smaller sub-units and stored across multiple distributed ledgers following a specific sequence, with the sequence information serving as a confidential key for reassembly, ensuring secure retrieval only with knowledge of the sequence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is stored in decentralized ledgers, then data availability and accessibility are improved, but data security and vulnerability to unauthorized access deteriorate
Solution Approach 1:
The patent divides a data object into multiple data portions and stores each portion in a different distributed ledger. This segmentation ensures that no single ledger contains the complete data, reducing the risk of full data exposure while maintaining accessibility through distributed storage.
Solution Approach 2:
The patent embeds sequence information within the data portions stored in distributed ledgers. This nested structure allows the system to store both the data fragments and the reconstruction instructions within the same decentralized infrastructure, enabling secure retrieval without centralized control.
2Object-affected harmful factors
If data is divided and stored across multiple distributed ledgers, then data security is improved, but system complexity increases
Solution Approach 1:
The patent introduces sequence information as an intermediary element that coordinates the storage and retrieval of data portions across multiple distributed ledgers. This mediator contains the necessary instructions for assembling the data portions in the correct order, simplifying the complexity of managing distributed data fragments.
3Object-affected harmful factors
If sequence information is kept confidential, then data retrieval security is improved, but ease of data reconstruction deteriorates
Solution Approach 1:
The patent extracts the sequence information from the data portions themselves and stores it separately in the distributed ledgers. This extraction allows the system to maintain security by keeping the sequence information confidential while enabling authorized users to retrieve and reconstruct data by accessing the separate components.
Data Source
AI summary
A method, computer system, and computer program product are provided for obfuscating and storing data. A data object is obtained comprising data for storing to a plurality of distributed ledgers. Sequence information is obtained indicating a number of a plurality of data portions into which the data object is divided, and instructions for storing the plurality of data portions to the plurality of distributed ledgers. The plurality of data portions is generated by dividing the data object according to the number. The plurality of distributed ledgers are determined to store the plurality of data portions based on the instructions indicated by the sequence information. The plurality of data portions is stored across the plurality of distributed ledgers by accessing the plurality of distributed ledgers, wherein each data portion is stored to a particular distributed ledger of the plurality of distributed ledgers according to the instructions indicated by the sequence information.
