NFT (Non-Fungible Token) has considerable potential in the field of intellectual property. It can not only improve the efficiency of copyright registration but also promote the improvement of transaction transparency and liquidity. However, existing copyright protection schemes of NFT image relied on the NFTs itself minted by third-party platforms. Also, the widespread use of NFTs has introduced new complexities to copyright protection due to their unique nature. Therefore, we have proposed a multi-layered blockchain security framework to resolve security vulnerabilities by protecting users from threats such as illegal copying, intellectual property rights infringement, and malware infection that may occur during the process of acquiring NFT assets through analysis of smart contracts, metadata, and digital assets that constitute NFTs.
