NFT Metadata Segmentation for Blockchain Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional NFT transaction technologies face limitations in convenience and flexibility due to restricted information referencing and centralized data management, which can lead to data falsification and storage location inflexibility.
Innovation Solution
An information processing system that generates metadata with a hash value and resource identifier, allowing for flexible content data management by recording metadata identifiers in a blockchain, enabling decentralized data management and flexible storage location options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content data is managed centrally in conventional NFT systems, then data management is simplified, but data integrity cannot be guaranteed and storage location flexibility is reduced
Solution Approach 1:
The patent segments the NFT data structure into multiple components: token data stored on-chain, metadata stored off-chain, and hash values linking them. This segmentation allows metadata to be stored flexibly while maintaining data integrity through cryptographic hashing, resolving the contradiction between reliability and management complexity.
Solution Approach 2:
The patent introduces hash values as intermediaries between the content data and the NFT token data. The hash value acts as a mediator that verifies data integrity without requiring centralized storage, enabling decentralized verification while maintaining reliability.
2Reliability
If metadata is stored on-chain, then data integrity is maintained, but storage flexibility and transaction speed are reduced
Solution Approach 1:
The patent extracts metadata from the on-chain token data and stores it off-chain in IPFS or other decentralized storage systems. Only the essential token data and hash values remain on-chain, providing both data integrity through hashing and storage flexibility through off-chain metadata, resolving the contradiction between reliability and adaptability.
3Loss of information
If all content information is included in NFT token data, then data completeness is improved, but blockchain storage efficiency and transaction speed deteriorate
Solution Approach 1:
The patent uses cryptographic hash values as compact representations of the original content data. Instead of storing all content information on-chain, the system stores only the hash value, which serves as a verified copy reference. This maintains information completeness through verification while dramatically improving transaction speed and storage efficiency.

AI summary
An information processing system includes a hash value acquisition unit for acquiring a hash value generated based on a key containing content data linked to a non-fungible token; a metadata generation unit for generating metadata for the content, the metadata including an electronic signature generated using the hash value and a predetermined secret key and a resource identifier referenced when acquiring the content data; a metadata identifier acquisition unit for acquiring a metadata identifier uniquely indicating the metadata; and a non-fungible token issuing unit for issuing a non-fungible token linked to the metadata and the content, by recording token data including the metadata identifier in a blockchain.
