Abstract

The short video application market has grown quickly due to the H. 264/H. 265 video compression technology. However, copyright conflicts and video security concerns have gained more attention as a result of this expansion. The current copyright notarization systems are plagued by issues with video traceability, opaque verification processes, and a lack of trust in the verification parties. This paper presented a smart contract-based encoding-level video security notarization technique as a solution to these problems. This strategy created a way to include copyright information by using the encoding properties of H. 264/H. 265 and inserting the copyright owner's information as a watermark during the video encoding process. The encoded information had a minimal effect on the quality of the video while guaranteeing the watermark's durability and security. Furthermore, it standardized the processes of identity notarization, copyright verification, and dispute settlement through the use of blockchain and smart contract technology, which raised the legitimacy and transparency of the execution process. According to experimental results, the similarity comparison algorithm employed for video copyright notarization performs better than the current best solution, with a F1-score that has grown by about 2%. Another test demonstrates that smart contracts have a manageable overhead, indicating their viability in real-world uses.
