Embodiment Construction

[0033] A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0034] Specifically, such as figure 1 As shown, the embodiment of the present invention provides a remote monitoring method for grain depots based on image encryption, respectively setting the sending end and receiving end of the monitoring video, specifically, including the following steps:

[0035] At the sending end, the following four steps are involved:

[0036] First, split the surveillance video to be transmitted into individual video frames, and each video frame contains a timestamp;

[0037] The time stamp refers to the mark of the time node formed by the video frame, which is an attribute of the video frame. Generally, in the present invention, due to the real-time nature of monitoring video transmission, the re...

Abstract

The invention discloses a grain depot remote monitoring system and method based on image encryption, and the method comprises the steps: segmenting a to-be-transmitted video frame before transmission,decomposing the to-be-transmitted video frame into a plurality of sub-images, randomly carrying out the encryption of each sub-image through employing a spatial domain image encryption technology ora compressed image encryption technology, packaging and transmitting the image encryption technology number corresponding to each sub-image at the same time, finally, obtaining each sub-image by usinga corresponding decryption technology according to the label of each sub-image and the corresponding image encryption technology number, and finally, splicing each sub-image according to the label ofeach sub-image to obtain an original video frame. According to the method, the sub-images are encrypted in a sub-image splitting mode and a random mode, so that the sub-images are cracked and restored by restoring each sub-image by using different types of decryption technologies, and then the disordered sub-images are restored, so that the technical difficulty of cracking and restoring is increased. Therefore, the security of data transmission is improved.

Description

technical field [0001] The invention relates to the field of remote monitoring, in particular to a system and method for remote monitoring of grain depots based on image encryption. Background technique [0002] Grain is an important strategic material related to the national economy and the people's livelihood. The national grain depot is an important unit responsible for food security and undertakes the central and local grain reserve tasks. In order to ensure the safety of grain storage, the grain depot has installed a large number of video surveillance equipment in the warehouse area and inside the granary to monitor the security of the warehouse area and the storage conditions in the grain warehouse. In addition to the monitoring and management of the grain depot itself, the higher authorities also need to conduct remote video monitoring. Therefore, the monitoring video of the grain depot needs to be transmitted to the superior monitoring center through the network. ...
