Cold Wallet Key Generation for Private NFT Author Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-fungible tokens (NFTs) issued through electronic wallets lack the ability to identify the original author or owner of digital assets, compromising privacy and authenticity, as they are signed with anonymous wallet owners' rights rather than the original authors' or owners' rights.
Innovation Solution
A cold wallet apparatus utilizing homomorphic encryption and physical unclonable function (PUF) technology to generate a private key by combining authentication codes from sensitive personal information and PUF information, ensuring the identity and privacy of the NFT issuer and owner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If personally identifiable sensitive information is included in NFT issuance information to identify original authors or owners, then the ability to identify original authors or owners is improved, but the privacy of original authors or owners deteriorates
Solution Approach 1:
The patent extracts only the necessary authentication code from personally identifiable sensitive information through homomorphic encryption, rather than storing or transmitting the complete sensitive information. This allows verification of original authorship while keeping the actual sensitive data private and secure.
Solution Approach 2:
Homomorphic encryption serves as an intermediary mechanism that enables authentication and identification without exposing the underlying sensitive information. The encrypted authentication code acts as a mediator that proves identity without revealing personal details.
2Loss of information
If existing electronic wallets are used for NFT issuance, then the anonymity of wallet owners is maintained, but the ability to identify original authors or owners deteriorates
Solution Approach 1:
The patent merges the anonymity feature of electronic wallets with the identification capability of personally identifiable information by combining homomorphic encryption of sensitive data with PUF information. This creates a hybrid system that provides both privacy protection and reliable identification of original authors.
Solution Approach 2:
The authentication system uses a composite approach combining multiple elements: homomorphic encryption of personal information, PUF hardware characteristics, and blockchain technology. This composite structure achieves both anonymity and identification capabilities that neither component could provide alone.

AI summary
The present invention relates to a cold wallet apparatus. The cold wallet apparatus includes a homomorphic encryption generation module configured to generate homomorphic encryption using personally identifiable sensitive information; a first authentication code extraction module configured to extract an authentication code from the homomorphic encryption; a second authentication code extraction module configured to extract an authentication code from physical unclonable function (PUF) information of the cold wallet apparatus; a private key generation module configured to combine the authentication code extracted from the homomorphic encryption and the authentication code extracted from the PUF information to generate a private key; and a transaction signature module configured to perform a transaction signature using a wallet account and a wallet address generated based on the private key.
