NFT-Based Data Access Management System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain infrastructure lacks an efficient and decentralized solution for managing and tracking data access rights, particularly in decentralized finance ecosystems, where reliable data delivery and authenticity are crucial but hindered by centralized management and monetization requirements.
Innovation Solution
A data access management system utilizing non-fungible tokens (NFTs) on a blockchain, where source NFTs (sNFTs) are minted and registered to authenticate data sources, and data NFTs (dNFTs) are generated and attributed to users for access rights, enabling secure, decentralized, and automated data access management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized management is used for data access rights, then data authenticity and reliability are improved, but system complexity and loss of trust are worsened
Solution Approach 1:
The patent extracts the centralized management function by removing the need for a central authority to verify data access rights. Instead, the system uses decentralized NFTs stored on a blockchain where access rights are inherently encoded in the token structure itself, eliminating the need for centralized verification while maintaining data authenticity.
Solution Approach 2:
The NFT-based system enables self-service verification where the blockchain and NFT smart contracts automatically validate access rights without requiring centralized intervention. The system serves itself by using the immutable characteristics of blockchain technology to enforce access control policies autonomously.
2Ease of operation
If centralized administration is used for data access management, then data access control is improved, but transparency and trust are worsened
Solution Approach 1:
The patent segments the data access management function into individual NFTs, each representing a specific access right. This segmentation allows for fine-grained control where different users can have different levels of access to different data, while the blockchain provides transparent recording of all access transactions without requiring centralized administration.
Solution Approach 2:
The system transitions from centralized administration (one-dimensional control) to a multi-dimensional decentralized structure where access rights are distributed across multiple NFTs on the blockchain. This dimensional change enables both precise access control and complete transparency through the immutable blockchain ledger.
3Extent of automation
If NFT-based decentralized management is used, then transparency and automation are improved, but computational complexity is worsened
Solution Approach 1:
The patent applies preliminary action by pre-encoding all access control logic, terms, and conditions directly into the NFT smart contracts before data access is needed. This preliminary setup automates the verification process, allowing the system to automatically determine and enforce access rights without complex real-time computational overhead during actual data access operations.
Data Source
AI summary
The present disclosure relates to data access management and the relates data access management system, user devices for data users and data sources, as well as to the corresponding methods. In some embodiments, a non-fungible token (NFT) registry is provided as a part of the data access management system, storing on a blockchain: source NFTs, each source NFT (sNFT) being uniquely associated with a data source; and data NFTs, each data NFT (dNFT) being attributed to one sNFT and granting access to the associated data source. The data sources may mint or request minting of the sNFT and the data users may mint dNFTs.
