Report file safety rule establishment method and device, equipment and storage medium

Abstract

The invention relates to a data processing technology, and discloses a report file safety rule establishment method, which comprises the following steps of: extracting text information of a report file to obtain a report information text; performing word segmentation operation on the report information text, and constructing a syntax tree by utilizing a word segmentation result to obtain a first report information word set syntax tree; performing word segmentation result preprocessing on the report information word set syntax tree by utilizing report file ontology knowledge, and updating the report information word set syntax tree to obtain a second report information word set syntax tree; according to a grammar analysis tree rule, utilizing the second report word set grammar tree to construct a grammar analysis tree; and establishing a safety rule of each tree node of the grammar analysis tree, constructing a safety rule structure tree, and completing establishment of the report file safety rule. The invention further provides a report file safety rule establishing device, equipment and a medium. According to the invention, the safety of the file can be improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method, device, electronic equipment and computer-readable storage medium for establishing report file security rules. Background technique [0002] Report files account for a large proportion of value in various enterprises, and untimely and abnormal location access by users will lead to the risk of leakage of private data in report files. Each enterprise will establish a security rule to protect the security of report files. [0003] At present, the establishment of security rules is generally to construct a security key outside the report file storage system to prevent external access. The viewing and reference of privacy report files cannot build security rules from the attributes of the report file itself. Contents of the invention [0004] The invention provides a report file security rule establishment method, device, equipment and storage medium, the main pur...
