The invention discloses a video data storage method based on a blockchain, and the method comprises the steps that monitoring equipment collects video data in a smart community, and uploads the videodata to an edge node; the edge node receives the video data and converts the video data into a tree structure; a cloud server sets a blockchain channel and sends block data in the blockchain channel to the edge node, wherein the block data is of a blockchain type storage type; after receiving the block data sent by the cloud server, the edge node inserts the block data into sub-nodes in the tree structure, wherein the sub-nodes comprise the block data, and the video data inserted with the block data is defined as block video data; the edge node uploads the block video data to the cloud server;when the other edge nodes request the cloud server to obtain the block video data, the cloud server performs authority verification on the other edge nodes; and after the verification succeeds, the cloud server sends the block video data to other edge nodes.
Description
technical field [0001] The present application relates to the field of information technology, in particular to a blockchain-based video data storage method. Background technique [0002] In smart communities, security monitoring is a very important field. In every corner of the smart community, it is necessary to collect video through monitoring equipment, give early warning, and ensure the personal safety of residents. Especially in more important areas, at least one high-definition monitoring device should be equipped to prevent dangerous or unexpected situations. [0003] However, in the current field of smart community security monitoring, video data has the disadvantages of being easily tampered with, unreliable, and easily lost. With the help of the current security encryption technology, the security of video data can be guaranteed to a certain extent, but it cannot be guaranteed Data loss, tampering, etc. Contents of the invention [0004] The embodiment of the...
