| Popis: | 107 Trust has been a major portion of the cost in copyright management. The high cost we pay for trust comes from the need of information validity. How to solve the cost of information asymmetry through blockchain to ensure the quality of information? The process of content production, copyright protection and record processing are great sources of cost. Such a cost issue can be oriented from judging copyright authenticity and being intruded by malicious person. Therefore, we need an effective copyright management mechanism to solve the problem. Blockchain technology can support copyright tracking and protection through a decentralized model and encryption algorithm. Moreover, through Blockchain’s Incorruptible feature, we can effectively deal with copyright tracking and protection issues. This study’s prototype will be established on Blockchain to solve the problem of copyright protection and tracking. This study implements the blockchain prototype structure in Ethereum and saves the transaction and copyright hash values and records on blockchain through smart contracts. Based on the trace ability of the blockchain, it ensures the transaction and copyright sources’ authenticity and ensure their integrity through hash values and time stamps. Under the framework of this digital copyright blockchain in this study, we found possible way to change the traditional system. Finally, traditional record processing cost and transaction cost can be reduced dramatically. |
