【Abstract】Video streaming applications are rapidly proliferating, allowing users to browse, download, and share videos through platforms such as YouTube, Netflix, and Amazon. Media content providers are required to register copyrights on digital platforms. With the existence of blockchain technology, users can manage their data using a smart contract, which allows them to define access and search policies and use an instant payment system without a third party in a decentralized network. We propose a secure and reliable video sharing scheme based on blockchain, using cryptographic primitives to secure the information of streamers and viewers. The use of blockchain ensures reliability and prevents the manipulating or forging of multimedia content. A smart contract system is implemented to represent contractual actions once a given access condition is satisfied. Analysis of the scheme's security and performance demonstrates that it is reliable and efficient.
