摘　　要：为保证监控视频数据的完整性和可信度,提出了一种基于哈希感知和区块链技术的视频存证方案。该方案利用哈希感知技术对上传视频进行哈希值检测,同时通过区块链的智能合约将视频的哈希值和存储地址通过广播事务发送并存储。在调取视频时,可以根据需求对视频进行溯源,将实时下载的视频数据与原始哈希值进行对比,以判断视频是否被篡改。实验证明,哈希感知技术能够检测出多种方式篡改的视频数据,有效验证了视频的完整性。该方案有效保障了视频来源和输出的安全性、可靠性。To ensure the integrity and credibility of surveillance video data,a video authentication scheme based on hash perception and blockchain technology is proposed.This scheme utilizes hash sensing technology to detect the hash value of uploaded videos,and sends and stores the hash value and storage address of the videos through broadcast transactions through a smart contract on the blockchain.When retrieving videos,it is possible to trace the source of the video according to the requirements,compare the real-time downloaded video data with the original hash value,and determine whether the video has been tampered with.Experimental results have shown that hash sensing technology can detect video data that has been tampered with in multiple ways,effectively verifying the integrity of the video.This scheme effectively ensures the security and reliability of video sources and outputs.
