Plaintext data tracing method and device based on file label

Abstract

The invention provides a plaintext data tracing method and device based on a file label. The method comprises the steps: scanning and recognizing the file type and the file sensitivity level of a plaintext data file; judging whether the plaintext data file has a file label or not; generating a file unique identifier; judging whether the plaintext data file has a file label or not, if not, generating the file label, and adding the file label into the data file; if the file label exists, judging whether the file sensitivity level is changed or not, and judging whether the file label is updated or not according to a judgment result; based on the file sensitive operation of the plaintext data file, reporting the file label information of the plaintext data file to a log stored in a server side; and correlating the records with the same unique identifiers of the files to generate a tracing report. According to the method, the plaintext data file with sensitive information is permanently traced, and related operations are reported in a log mode, so that the leakage risk is conveniently found, and the enterprise data security is improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and device for tracing plaintext data based on file tags. Background technique [0002] At present, with the increasing emphasis on data in various industries, data security issues have gained the attention of data users. As an important branch of information security, data security is widely valued by different industries. A data security management system has emerged as a means of data security protection, and the current data security management system is gradually developing in the direction of intelligence to fit the user's usage habits. [0003] There is a terminal based on a data security management system, which relies on the full-disk scanning function and the file label in the document to realize the traceability of plaintext data. The prior art 201810265186.1 is a plaintext data traceability method developed based on the sensitive data scanning function, ...

Problems solved by technology

[0004] In order to solve the above technical problems, the present invention proposes a method and device for tracing plaintext data based on file tags. The method and device are used to solve the problem that there is no unified management method for file tags in the prior art, and file tags cannot The management of the whole process of file use, whether there is a leak in the file and the technical problem of slow query speed for all leak scenarios
