论文摘要
区块链技术引起了各种社区的关注。基本共识机制Inblockchain为存储数据的完整性添加提供了无数的应用。在本文中，我们利用BloxChaintechnology来验证通过从体系设备捕获的视频的真实性，以进行法医调查。 Proped方法计算视频框架的哈希夫人离开物联网设备，并转移到遥控基础上。为了确保传输，我们确保通过基于TCP的连接发送此障碍。然后将哈希在许可的区块链平台上进行Stordon多个节点。如果对视频进行了修改，将通过对先前存储的区块链上存储的哈希进行评估并将其与所讨论的现有框架的哈希进行分配，从而检测到差异。在这项工作中，我们将原型介绍为具有经验结果的原型。该系统已在RaspberryPI上进行了测试，并具有不同质量的视频以评估性能。这些概念可以通过中度效率分辨率实现。
Blockchain technology has drawn attention fromvarious communities. The underlying consensus mechanism inBlockchain enables a myriad of applications for the integrityassurance of stored data. In this paper, we utilize Blockchaintechnology to verify the authenticity of a video captured by astreaming IoT device for forensic investigation purposes. Theproposed approach computes the hash of video frames beforethey leave the IoT device and are transferred to a remote basestation. To guarantee the transmission, we ensure that this hashis sent through a TCP-based connection. The hash is then storedon multiple nodes on a permissioned blockchain platform. Incase the video is modified, the discrepancy will be detected byinvestigating the previously stored hash on the blockchain andcomparing it with the hash of the existing frame in question.In this work, we present the prototype as proof-of-concept withexperiment results. The system has been tested on a RaspberryPi with different quality of videos to evaluate performance. Theresults show that the concept can be implemented with moderatevideo resolutions.
