NFT Content Watermarking for Fast Illegal Registration Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NFT content registration systems consume significant computer resources and time due to the need for collating with all registered images to prevent illegal registration of digital art.
Innovation Solution
A system that generates and verifies NFT content by reversibly watermarking images with identification information using multiple keys and algorithms, allowing efficient detection of illegal registrations without extensive collation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If collation with all registered images is performed to prevent illegal registration, then reliability of preventing illegal registration is improved, but computer resources and time are greatly consumed
Solution Approach 1:
The patent applies preliminary action by embedding reversible watermarks with identification information into NFT content during the registration process. This preprocessing step enables rapid verification later without requiring exhaustive collation with all registered images. The watermark contains encoded identification data that can be quickly extracted and verified, eliminating the need for time-consuming full-image comparison while maintaining reliable illegal registration detection
Solution Approach 2:
The patent extracts essential identification information from the NFT content by embedding it as a reversible watermark. Instead of storing or comparing entire images, the system extracts and verifies only the critical identification data embedded in the watermark. This extraction approach dramatically reduces the data volume requiring processing during verification, thereby reducing computer resource consumption and processing time while maintaining the ability to reliably detect illegal registrations
2Reliability
If collation with all registered images is performed to prevent illegal registration, then reliability of preventing illegal registration is improved, but computer resources are greatly consumed
Solution Approach 1:
The system performs preliminary watermarking during registration, embedding identification information that enables fast verification. This advance preparation eliminates the need for resource-intensive full-image collation during verification operations, significantly reducing computer resource consumption while maintaining reliable illegal registration prevention
Solution Approach 2:
The system extracts and verifies only the essential identification information from watermarks rather than processing entire images. This selective extraction of critical data reduces the computational burden and memory requirements, thereby conserving computer resources while maintaining the reliability of illegal registration detection

AI summary
A non-transitory computer-readable recording medium stores therein a Non-Fungible Token (NFT) content processing program that causes a computer to execute a process including, when receiving a registration request including first NFT content to be registered and identification information (NFT_ID) for identifying the first NFT content, generating second NFT content in which the first NFT content is reversibly watermarked with the identification information based on a predetermined first key by using a first algorithm, registering the generated NFT content, when receiving a verification request including third NFT content to be verified, restoring identification information added as a watermark to the third NFT content from the third NFT content based on the first key by using the first algorithm, and making a notification of a verification result based on the restoration of the identification information added as a watermark to the third NFT content.
