Data classification method and device and storage medium

Abstract

The invention relates to the technical field of network information security, in particular to a data classification method and device and a storage medium, which are used for improving sensitive data classification accuracy, and the method comprises the following steps: obtaining to-be-detected data information; matching the to-be-detected data information with each sensitive information label in a preset sensitive information base to obtain a first classification label matching the to-be-detected data information, and based on a trained classification model, carrying out sensitive information classification on the to-be-detected data information to obtain a corresponding second classification tag; if the first classification tag is inconsistent with the second classification tag and the confidence coefficient of the second classification tag is not greater than a preset threshold value, taking the first classification tag as a target classification tag corresponding to the to-be-detected data information; and if the confidence coefficient of the second classification tag is greater than a preset threshold value, taking the second classification tag as a corresponding target classification tag. Tthe safety protection capability on the sensitive data is improved by fusing the results matched based on the sensitive information base and the neural network.

Description

technical field [0001] The present application relates to the technical field of network information security, and provides a data classification method, device and storage medium. Background technique [0002] The era of big data is the era of the Internet of Everything. Data classification and classification, as the "bridgehead" of data security, are crucial in the process of data security governance. At present, with the development of big data, artificial intelligence and Internet of Things technology, how to effectively protect personal privacy and protect corporate sensitive data from being leaked has become the focus of more and more security vendors. To this end, it is necessary to focus on the management and control of sensitive data, and implement different security protections according to different data levels to avoid major losses caused by sensitive data leakage.

Problems solved by technology

[0003] In related technologies, for the problem of how to classify and classify sensitive data, it is mainly a classification and classification system based on pre-established rules, or a classification and classification system based on a neural network model. Weak, lack of reusability and sharing of knowledge; although the classification and grading system based on the neural network model can solve the above problems, the neural network lacks interpretability
