Problems solved by technology

As we all know, video surveillance data are generally stored in the park. When law enforcement agencies and parents request to view the video surveillance, the relevant responsible person will always cause the loss of surveillance video or some key elements in the surveillance video due to damage to the camera or hard disk for video storage. Due to the lack of pictures to evade, law enforcement agencies cannot effectively collect evidence, and thus cannot quickly and effectively punish criminals

Embodiment Construction

[0068] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0069] Such as figure 1 As shown, it is assumed that there are five independent and peer-to-peer nodes: node camera, node 1, node 2, node 3 and node 4, which together constitute a P2P video surveillance network. The video data source comes from the node camera, and the data generated by the camera in the node camera is sent to its adjacent nodes (node ​​1 and node 2) in the P2P network, and then forwarded by these adjacent nodes to other adjacent nodes (Node 3 and Node 4), so that all other nodes in the entire P2P network except the node camera will receive video data in a short time. Each time the four nodes except the node camera receive the video frame data, they must first check the integrity of the video frame data to prevent loss or damage of the video frame data, and the detected video frame data will be put into the node The local video f...

Abstract

The present invention proposes a block chain technology, relying on the video monitoring P2P network to prevent the occurrence of abnormal situations such as video content being tampered with, video content loss, and how to restore these abnormal video content. The present invention designs a reasonable and efficient anti-tamper data structure, including node type, video frame data structure, video block structure and video block chain structure, etc. The anti-tampering method can effectively prevent the video data from being tampered with, and the tampered video data can be restored through the synchronization method.

Description

technical field [0001] The invention relates to the technical field of block chain, in particular to a method for realizing tamper-proof, loss-proof and recovery of video content by using block chain technology. Background technique [0002] Blockchain technology is a new application model that integrates computer technologies such as distributed data storage, point-to-point transmission network, consensus mechanism, and encryption algorithm. [0003] In a narrow sense, a blockchain is a chronological order in which blocks composed of data are sequentially connected with the help of hash pointers to form a chained data structure, while cryptographically ensuring that the data in the block It cannot be tampered with, and this chained data structure is stored independently in different nodes, and the consensus mechanism ensures the consistency and unforgeability of data stored in different nodes. [0004] In a broad sense, the blockchain uses a block chain data structure to v...
