Network data security management method and equipment

Abstract

The invention relates to a network data security management method and network data security management equipment. The network data security management method comprises the following steps of: acquiring network data; extracting a sample to be matched from the network data; calculating a voice distance and / or a semantic distance between the sample to be matched and at least one pre-stored keyword according to a distance algorithm; acquiring a weight value corresponding to a keyword which is at a distance which exceeds an ambiguity threshold value away from the sample to be matched; calculating a security value of the network data according to the weight value; and determining that the network data are secure network data if the security value does not exceed a preset security value, otherwise determining that the network data are insecure network data. By using the technical scheme, sensitive data can be accurately filtered and early-warned, and a pseudo-matching phenomenon can be avoided, so that the security of the network data is enhanced, and the method and the equipment are practical.

Description

technical field [0001] The invention relates to a network data security management technology, in particular to a network data security management method and equipment. Background technique [0002] With the wide application of terminal devices with interconnection characteristics such as computers, networks (such as the Internet or local area networks or mobile communication networks, etc.) have been deeply popularized in all walks of life in society. [0003] The rapid development of the network not only provides a lot of convenience for people's work, study, and entertainment, but also brings new problems to people. Among them, the network data management problem, especially the network data security problem, has become a problem for many people. The focus of the industry is very concerned about. For example, the State Grid Corporation of China is vigorously promoting the construction of the "SG186" project and power communication, and the blueprint for digital power gri...

Problems solved by technology

[0005] In the process of realizing the present invention, the inventor found that: due to the phenomena of homonyms and synonyms of different words in words, the existing network data security management method cannot be sensitive to sensitive data in the case of keyword matching and filtering. Accurate filtering and early warning of data, which will cause illegal content to deceive the filter and successfully leak

In addition, because the network data security management method ignores the semantic constraints in the text, a large number of false matches will be generated, thereby filtering out legitimate content
