From the above description, it can be observed that there is an urgent need for advanced mechanisms to solve various problems existing in the registration, confirmation, and transfer of digital rights during the process of digital rights protection. One possible solution is the use of blockchain technology. The Blockchain technology originated in 2008 and was once used as the public transaction ledger of cryptocurrency which name is bitcoin. Researchers said that blockchain has the potential to be widely used in copyright protection and management. The digital copyright data is contained in the block. Each block is linked to the blockchain in the form of a timestamp through the hash pointer pointing to the hash value of the previous block. In this way, it guarantees that digital copyright information cannot be manipulated. Blockchain can significantly reduce the cost of digital copyright protection, improve efficiency, and provide new ways to collect evidence, trade digital assets, and protect the rights of copyright owners. This technology has greater transparency and centrality than the traditional publishing technology, and cannot be changed at will. Therefore, great changes have taken place in all aspects of copyright protection technology (Crosby et al., 2016). According to the distribution of blocks, blockchain technology can be divided into the public blockchain, alliance blockchain, and private blockchain. It has the characteristics of decentralization, openness, independence, security, and anonymity. It is widely used in the Internet of Things (IoT) and logistics, public service, digital copyright, insurance, and public welfare.
A design scheme of copyright management system based on digital watermarking and its information is proposed by Meng et al. (2018). It combines digital watermarking, blockchain, perceptual hash function, fast response code, and InterPlanetary File System (IPFS). 2b1af7f3a8
