A Study on Integrated Framework for Copyright Protection Based on Multi-signature in NFT

초록

These digital contents are easily modified and reproduced, and they spread widely. In this environment, there is a frequent occurrence of copyright infringement and misuse of digital content, raising new issues regarding intellectual property rights and the preservation of ownership. By allowing multiple users to collaborate on the signing process, the entire system is less susceptible to risks associated with a single individual’s exposure. 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 themselves minted by third-party platforms. In this paper, 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. Each party can sign the consensus of the transaction or contract, increasing transparency and efficiently protecting the ownership and copyright of digital contents. Therefore, we have proposed a multi-signature scheme based on the Schnorr scheme in NFT. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2026.
