The invention discloses a data filtering mining method with a primary screening function, which relates to the technical field of data security and comprises the following steps of: firstly establishing sensitive word database feature codes; Then calculating a data feature code when the user accesses the webpage; Secondly, comparing the webpage data feature codes accessed by the user with sensitive word database feature codes, and judging that the data accessed by the user is sensitive data when the number of the webpage data feature codes accessed by the user and the sensitive word database feature codes obtained in the third step are the same as a set threshold value; And finally, when it is judged that the webpage data feature code accessed by the user is sensitive data, filtering and coding sensitive words in the webpage data feature code accessed by the user. According to the method, the sensitive word database feature codes are established, the internet surfing behavior of the user is monitored in real time, the defect that pornographic websites cannot be filtered is overcome, and the purpose of green internet surfing is achieved.
Description
technical field [0001] The invention relates to the technical field of data security, in particular to a data filtering and mining method with a primary screening function. Background technique [0002] The International Organization for Standardization (ISO) defines computer system security as: the security protection of technology and management established and adopted for data processing systems to protect computer hardware, software and data from being damaged, changed and leaked due to accidental and malicious reasons. . Therefore, the security of the computer network can be understood as: through the use of various technical and management measures to make the network system run normally, so as to ensure the availability, integrity and confidentiality of network data. Therefore, the purpose of establishing network security protection measures is to ensure that the data transmitted and exchanged through the network will not be added, modified, lost and leaked.
