Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with specific examples, but the embodiments of the present invention are not limited thereto.

[0025] The embodiment of the present invention provides a block chain-based image monitoring method, such as figure 1 As shown, the method includes the following steps:

[0026] S10: Receive monitoring images.

[0027] Here, the monitoring image is received by the execution subject of the image monitoring method, that is, the monitoring image is received by the blockchain network node.

[0028] S20: Invoking a preset smart contract to extract key data from the surveillance image; the key data is used to characterize personnel information and / or event information captured by the surveillance image.

[0029] Specifically, the monitoring data may be the image of the person in the monitoring image, the image of the preset area in the monitoring image, the name or logo of the person in the monitoring ...

Abstract

The invention discloses an image monitoring method based on a block chain. The method comprises the following steps: receiving a monitoring image; calling a preset intelligent contract to extract key data from the monitoring image; the key data is used for representing personnel information and/or event information shot by the monitoring image; uploading the key data to a block chain network to perform consensus verification on the key data; and after the consensus verification is passed, writing the key data into the block of the block chain network. According to the method, the storage space is effectively reduced, the key data cannot be cleared or invalid, and the key data cannot be tampered.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to an image monitoring method based on block chains. Background technique [0002] In the prior art, after the monitoring image is taken locally, the monitoring image is uploaded to the server for storage. When the monitoring image needs to be queried, the monitoring image is retrieved from the server. The problem with this approach is that the server needs to periodically clear the historically stored surveillance images, otherwise the storage will fail due to insufficient storage space. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a block chain-based image monitoring method. [0004] The technical problem to be solved in the present invention is realized through the following technical solutions: [0005] A block chain-based image monitoring method, comprising: [...
