Network illegal information monitoring method and system based on video capture

Abstract

The invention relates to a network illegal information monitoring method and a system based on video capture. A display content is collected through the information collection module, feature blocks are identified for the display content after preprocessing so that a threat information feature library can be compared in the next step, and after threat matching is conducted on the feature blocks, if illegal information exists, real-time alarming is conducted through the wireless communication module, and manual intervention is conducted through the network malicious information blocking module.The working principle is simple, illegal information of pictures, videos and web pages in LED large screens and public place display screens can be detected in time and can be effectively detected and shielded and blocked in time, the probability of harm caused by the illegal information is reduced, and meanwhile the security level of network information of workplaces is improved.
