NFT-Based Data Access Control for IoT Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing data exchange processes are hindered by issues of data privacy concerns, divergent business interests, and lack of trust among entities generating, storing, and accessing data, leading to slow and unreliable interactions, especially in sectors like automotive and logistics where IoT data is involved.
Innovation Solution
A system utilizing Non-Fungible Tokens (NFTs) and smart contracts on a digital ledger network to control and negotiate access to private data objects, allowing secure and trusted transactions between buyers and sellers by using a trusted third-party to facilitate data access and ownership.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional data exchange processes are used, then data access can be achieved, but the process is slow and unreliable due to manual negotiations and lack of trust
Solution Approach 1:
The patent introduces a blockchain-based intermediary system that acts as a trusted mediator between data owners and data seekers. The blockchain network verifies and records all data access transactions, eliminating the need for direct trust between parties. Smart contracts automatically enforce access agreements, while NFTs provide verifiable ownership proofs, thereby resolving the trust issue without slowing down the exchange process.
Solution Approach 2:
The patent implements preliminary actions by pre-registering data objects on the blockchain with NFT tokens that encode access rights and ownership information. Data owners can pre-configure access policies and pricing structures before actual data requests occur. This preparation work is done in advance, allowing rapid verification and execution when data access requests are made, thereby improving exchange speed while maintaining reliability through pre-established trust mechanisms.
2Adaptability or versatility
If data is made accessible to researchers and analysts, then data utility increases, but data privacy and security concerns arise
Solution Approach 1:
The patent segments data access rights by issuing different types of NFT tokens that represent various levels of access permissions. Instead of providing blanket access, the system divides data access into discrete, controllable units where owners can grant specific permissions to specific parties for specific purposes. This segmentation allows broad data accessibility while maintaining granular control over privacy and security concerns.
Solution Approach 2:
The blockchain acts as an intermediary that enables data accessibility without exposing raw data to unauthorized parties. The system verifies access rights, manages permission transfers, and enforces usage policies through smart contracts, thereby allowing researchers and analysts to access data utility while the blockchain intermediary protects data privacy and security by preventing unauthorized access and misuse.
3Ease of operation
If manual data access negotiation processes are used, then data ownership control is maintained, but the process becomes complex and time-consuming
Solution Approach 1:
The patent implements self-service mechanisms where data owners register their data objects on the blockchain and receive NFT tokens that automatically encode their ownership and access control rights. When data access is needed, parties can independently verify ownership and negotiate terms through standardized smart contract templates without requiring manual intervention from intermediaries. The blockchain network automatically executes agreed-upon access terms, dramatically simplifying the process and reducing negotiation time while maintaining owner control.
4Reliability
If NFT tokens are used to represent data objects, then ownership verification is improved, but system complexity increases
Solution Approach 1:
The patent makes the NFT token system multi-functional to justify and manage its complexity. The same NFT infrastructure serves multiple purposes: proving data ownership, managing access permissions, tracking data provenance, enabling secure transactions, and recording usage history. By consolidating these functions into a single unified blockchain-based NFT system rather than separate mechanisms for each function, the patent improves ownership verification reliability while preventing exponential growth in system complexity through functional integration.
Data Source
AI summary
A computing device and computer-implemented method to provide access to a private data object is described. The system uses Non-Fungible Tokens (NFT) and smart contracts as a mechanism to provide access to data. The information to which the token refers, e.g., the artwork, is viewable by everyone as part of a digital ledger network. The token is used only to determine who owns that item. The present approach offers an alternative for using NFT, so that access to the information itself to which the token is linked is controlled and negotiated by the token owner. The present invention can be applied to any IoT network that performs data collection that is of interest to companies or organizations outside the network in which the collection was performed, allowing to identify the ownership of IoT devices. Thus, enabling access control to the device's data, by their owners, directly through the blockchain.
