“…Once the system fails to deal with the error in time, the attacker will steal the user information and data through the system design defect, and the service equipment data will be leaked. Fourth, the problem of illegal intrusion is mainly that some criminals on the Internet use the user login name or instructions to invade the user's system terminal, generally steal or falsely use the trusted host or user to enter the electronic computer system, and use the way of stealing IP address to invade the terminal to steal network information [5,6]. Figure 1 shows the antileakage technology of computer video information encryption.…”

In order to better realize and ensure the security performance of network information itself, various possible risks must be prevented in advance, and a more reliable operation environment must be created as much as possible. A research study on computer video information encryption and antileakage technology based on the digital information method is proposed. Through the research on the working principle of computer display systems, this paper analyzes the common leakage sources. On this basis, it analyzes how to protect the electromagnetic wave leaked from the computer display system. Finally, it is proposed that the protective measure adopted in this paper is (transient electronic pulse emission survey technology, tempest) technology; that is, the image is processed at the source of image information to reduce the electromagnetic radiation of useful information. The corresponding digital filter is designed by fir, and the combined filtering of digital filter and analog filter is applied to eliminate the inherent disadvantage of periodic fluctuation of insertion loss of the digital filter. The research results show that the receiver before filtering can receive video images at multiple frequency points such as 20 MHz, 160 MHz, 220 MHz, 250 MHz, 270 MHz, 290 MHz, and 340 MHz, while the receiver after filtering can only receive video images at two frequency points of 20 MHz and 250 MHz, but it cannot recognize the words in the figure, and its effect is very obvious. It verifies the correctness and effectiveness of the theoretical analysis in this paper.

“…Another result of this study is that leaks and ruptures can cause other accidents, the root causes of which include decay, improper maintenance and repair of equipment, and failure to inspect the internal pressure of pipes and pressure vessels. The study by Jia et al in 2021 also confirmed this finding [ 29 ].…”

“…However, most of the references are presented as a ''black box,'' which typically presents highly concise results, lacking details of the results of accident analysis. 16,33 However, the graduation thesis samples used by Goncalves Filho et al 31 provide inspiration for this study: the graduation thesis is peer reviewed and the quality is guaranteed. In addition, the length of the graduation thesis is relatively small, which allows the author to list some ''raw meat'' data in the attached table to provide more details of the sample.…”

Accident prevention depends on accident analysis. In order to improve the reliability of accident analysis and find the common problems related to reliability in accident analysis, two groups of four papers of master’s and doctor’s theses which applied 24Model to analysis coal mine gas explosion accident were selected as samples. The unsafe act results obtained from the analysis are compared. The results show a low consistency level, which reflects that the reliability of the output needs to be improved. Through analysis, the inconsistency of details in causes description, the difficulty in the cause description and the omission of unsafe acts are the main reasons leading to the above situation. In order to standardize the description of cause items, the components of unsafe acts were defined as “premise + action”, and seven types of premises were summarized to judge unsafe acts. In order to improve the efficiency and reliability of accident analysis, it is suggested that the current data should be taken as reference, and the taxonomy based on consequences should be established to unify unsafe act detail description level, and the corresponding computer software should be developed to assist accident analysis.
