Abstract Digital assets have boomed over the past few years with the emergence of Non-fungible Tokens (NFTs).

Abstract With the rapid development of digitization technology, digital copyright of museum has become more and more valuable.

However, centralized authorization, untransparent transaction information and risk of tampering data in traditional digital rights management have a strong impact on system normal operation. In this paper, we proposed a blockchain-based digital rights management scheme (BMDRM) that realizes a distributed digital rights management and authorization system by introducing non-fungible tokens (NFTs) and smart contracts. To ensure the security and efficiency of transactions and authorization, we store all processing data… More >
