Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blockchain-based systems for managing non-fungible tokens (NFTs) face challenges such as high energy consumption, environmental impact, and barriers to entry due to technical and cost issues, while also lacking efficient mechanisms for centralized generation and transaction of NFTs.
Innovation Solution
A method and apparatus for managing NFTs without using blockchain technology, which involves generating NFTs through a centralized server, adding certification authority (CA) and ownership signatures, and transmitting them to external devices, utilizing multi-signature-based technology for secure and efficient management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain technology is used to generate and manage NFTs, then transparency and authenticity are ensured, but energy consumption increases and environmental impact worsens
Solution Approach 1:
The patent extracts the essential function of blockchain (providing transparency and authenticity through cryptographic signatures) while removing the energy-intensive distributed consensus mechanism. The system uses a centralized server to generate NFTs with CA signatures and ownership signatures, achieving the same security goals without blockchain's energy consumption.
Solution Approach 2:
The patent introduces a centralized server as an intermediary that issues NFTs with cryptographic signatures. This mediator replaces the distributed blockchain network, providing the same authentication function while eliminating the need for energy-intensive consensus protocols across multiple nodes.
2Reliability
If blockchain technology is used to generate and manage NFTs, then transparency and authenticity are ensured, but entry barriers increase due to technical and cost issues
Solution Approach 1:
The patent removes the complex blockchain infrastructure requirement from the NFT generation process. Users can obtain NFTs with the same level of cryptographic security through a simple centralized server interface, eliminating the need to understand or interact with blockchain technology.
Solution Approach 2:
The patent creates a simplified copy of the blockchain NFT generation process that retains the essential security features (CA signatures, ownership signatures) while eliminating the complex distributed ledger infrastructure. This allows widespread adoption without requiring users to engage with blockchain technology.
3Adaptability or versatility
If blockchain technology is used to generate and manage NFTs, then decentralized ownership is achieved, but device complexity and cost increase
Solution Approach 1:
The patent uses a centralized server as a mediator that issues NFTs with cryptographic signatures enabling decentralized ownership verification. The server handles the complexity of key management and signature generation, while users can verify ownership independently using the provided cryptographic data, achieving decentralized verification with centralized issuance.
Data Source
AI summary
An electronic device and method are disclosed for managing a non-fungible token (NFT). The electronic device includes: a memory configured to store computer-executable instructions, and a processor. The processor implements the method, including: generating, a NFT for target content in response to receiving a request to register the target content from a first external electronic device, generating, for the NFT, a certification authority (CA) signature indicating that the NFT is generated by the server, and transmitting, via a communication circuitry, the NFT to the first external electronic device, wherein an ownership signature is added to the NFT, together with the CA signature, the ownership signature based on a private key of a user to which ownership of the NFT is assigned.
