Hiding Data into Blockchain-based Digital Video for Security Protection

The legitimate owner interests protection of traditional digital videos has become an increasingly demand with the rapid development of internet video applications. The development of Blockchain, which provides decentralization, traceability, and high credibility attributes has provided a technical inspiration for digital video legitimate interests protection. In this paper, we propose a novel and effective security protection framework by hiding secret data in the digital video of the Blockchain network. On the Blockchain network side, we upload the secret data referred to video to Blockchain network; on the traditional server side, we use smart contract to manipulate the procedures of embedding and extraction of secret data which has been embedded into digital video. Then, we could verify, trace and protect the secret data which are stored into Blockchain network and digital video contents itself, respectively. It is proven that the proposed framework could achieve high efficiency and accurate performance on digital video security protection.
