NFT Image Validation Before Minting With Bijective Functions

Solution Overview

Problem

Current blockchain systems lack effective mechanisms to prevent the unauthorized creation and trading of stolen NFT art, as existing authentication methods only verify ownership after the fact and do not prevent illegal minting.

Innovation Solution

A blockchain-based system that utilizes bijective functions to validate NFTs by comparing image pixel matrix data across various formats, ensuring unique identification and preventing duplicate uploads, with a two-layer validation process to detect collisions and small changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing authentication mechanisms are used, then NFT creation is simple and fast, but ownership verification only occurs after theft and illegal minting is discovered

Engineering Contradiction:

Improveownership verificationVSAvoidtime to detect theft

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by performing bijective function validation on image files before NFT minting occurs. The system scans the blockchain for duplicate images, converts images to various formats, calculates bijective function values, and compares them against a validation database of existing NFT images. This pre-verification prevents theft detection delays by stopping illegal minting before it happens, rather than discovering it after the fact.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If blockchain allows free NFT minting, then accessibility and ease of creation are high, but duplicate and stolen art can be uploaded multiple times without obstacles

Engineering Contradiction:

ImproveNFT creationVSAvoidduplicate uploads

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary validation system between the user and the blockchain minting process. The validation node acts as a mediator that intercepts NFT creation requests, performs bijective function validation by converting images to multiple formats and comparing hash values against existing NFTs, and only allows minting if the image is unique. This intermediary layer maintains ease of operation for legitimate users while blocking harmful duplicate uploads.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system applies preliminary anti-action by proactively preventing duplicate NFT minting before it occurs. The validation database stores bijective function values of existing NFT images, and before allowing new minting, the system calculates the bijective function of the submitted image and checks for collisions. This preemptive measure counteracts the harmful effect of duplicate uploads by blocking them in advance.

Inventive Principle:

Principle #9Preliminary anti-action

3Device complexity

If authentication is performed after NFT creation, then the system remains decentralized and simple, but it cannot prevent theft and illegal minting

Engineering Contradiction:

Improveauthentication systemVSAvoidtheft prevention

Core Design Contradiction:

AI summary

An example NFT validation operation may include one or more of receiving an NFT creation request by an NFT processing node connected to a peer-to-peer file storage protocol system node over a blockchain; scanning, by the NFT processing node, the blockchain for an image file reference based on the request; retrieving, by the NFT processing node, the image file from the peer-to-peer file storage protocol system based on the image file reference; extracting, by the NFT processing node, image pixel matrix data from the image file; converting the image pixel matrix data into a plurality of image formats data; calculating a plurality of values of a bijective or hash function of each of the plurality of image formats data; and validating the NFT by comparing the plurality of the values of the bijective or hash function against pre-stored in a validation database value vectors comprising the plurality of values of the bijective or hash function of existing NFT images.
