A Video Security Verification Method Based on Blockchain

This paper proposes a blockchain-based video security verification method. In order to ensure the security of the video, we use data hiding technology to embed message that can ensure the security of the video into the video, at the same time, in order to improve the non-tamperability and non-forgery of data hiding. We construct the hash value of the message embedded in the miginal video, the hash value of the carrier video (video with embedded message) and the attribute message of the video as video metadata, and upload the video metadata to the blockchain network. Comparing the message extracted from the carrier video with the video metadata stored on the blockchain can achieve double verification of the video. At the same time, distributed storage of carrier video through IPFS can effectively store and manage large-scale video data, ensuring the security and high availability of videos.
