Design And Implementation Of Information Screening System For Satellite Internet Access Device

In recent years,the rapid development of satellite Internethas brought new challenges to China's Internet harmful information supervision.Raising and analyzing these challenges and considering countermeasures at the earliest stages are essential to the effective regulation of satellite Internet.Screening the sensitive information transmitted by satellite Internet access equipment is a direct,flexible,and highly targeted regulatory means,which is of great significance of the regulation of satellite Internet.The main contents of this thesis are as follows:1.This thesis investigates various types of satellite Internet,introduces the development of satellite Internet,analyzes the risks caused by the development of satellite Internet,points out the importance and urgency of risk treatment,and focuses on the methods of satellite Internet control.2.This thesis proposes a sensitive information screening scheme for satellite Internet access device,and designs a sensitive information screening system for satellite Internet access device.In the design process,consider the mobility and similarity of satellite Internet access device to other network access device.Considering the perspective of access device monitoring,content analysis,and operator,the entire system is designed into three modules:a monitoring module,a content analysis module,and an operation center.This thesis also designs the communication protocol between the modules in order to realize the effective transfer of data and messages in distributed scenarios.3.This thesis studies the current sensitive information screening methods of the Internet,and proposes a deep learning-based sensitive information screening scheme,which effectively reduces the rate of misjudgment and improves the efficiency of manual review.In terms of reducing the rate of misjudgment,this solution brings the determination of sentiment tendency into the screening process of to avoid misjudgment caused by the way of matching only sensitive words.In terms of improving the efficiency of manual review,this solution uses the summarization algorithm to convert long texts into short texts,which can reduce the workload of a single manual review.
