Embodiment Construction

[0019] The embodiment of the present invention provides a block chain-based image monitoring system, as shown in Figure 1, the system can include

[0021] The monitoring host is used to preprocess the monitoring image, and

[0022] The preprocessing mentioned here may include image downsampling, grayscale processing and other processing methods.

[0026] The block chain network node detects whether the preprocessed monitoring image contains one or more preprocessed images.

[0027] Wherein, the facial recognition information contained in the monitoring image can be detected by means of facial recognition. Additionally, if

[0032] In response to the key data containing the preset target personnel personnel information or the fire image information,

[0035] Although the application is described herein in connection with

Abstract

The invention discloses an image monitoring system based on a block chain, and the system comprises an image collection device which is used for photographing a monitoring image, and transmitting the monitoring image to a monitoring host; the monitoring host is used for preprocessing the monitoring image and sending the preprocessed monitoring image to the block chain network node; the block chain network node is used for calling a preset intelligent contract to extract key data from the received monitoring image; the key data is used for representing personnel information and / or event information shot by the monitoring image; and uploading the key data to a block chain network to enable the key data to be subjected to consensus verification by all block chain network nodes, and writing the key data after the consensus verification is passed into a block which is maintained by the key data and corresponds to the block chain network. According to the method, a large local storage space is not needed, the key data cannot be cleared or invalid, and the key data cannot be tampered.

Description

A blockchain-based image monitoring system technical field [0001] The invention belongs to the technical field of blockchain, and in particular relates to a blockchain-based image monitoring system. Background technique [0002] In the prior art, after the image acquisition device captures the monitoring image locally, it can store the monitoring image or The control image is uploaded to the host for saving. When the user needs to query the monitoring image, the image acquisition device or host can be to retrieve monitoring images. The problem with this approach is that it is necessary to periodically clear the image acquisition device and the history stored in the host. Otherwise, the storage will fail due to insufficient storage space. SUMMARY OF THE INVENTION In order to solve the above-mentioned problems existing in the prior art, the present invention provides a kind of image monitoring based on block chain system. The technical problem to be solved by the...
