Embodiment Construction

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] Such as figure 1 and figure 2 As shown, the present invention provides a method for reducing the misjudgment rate of sensitive information, comprising the following steps:

[0027] S01: Obtain documents that are judged as sensitive information by the sensitive information detection system (these documents contain documents that are not actually sensitive information, such documents are caused by system judgment, that is, false positive documents);

[0028] S02: Perform data processing on documents judged as sensitive information;

[0029] S03...

Abstract

The invention relates to a method for lowering a sensitive information misjudgment rate. The method comprises the following steps that documents with sensitive information judged by a sensitive information detection system are obtained; the documents with the sensitive information judged are subjected to data processing; the sensitive information documents subjected to data processing are clustered, a clustered result is obtained, and a specialist judges sensitive information according to the clustered result. According to the method for lowering the sensitive information misjudgment rate, a cluster rejudgment module is added to a module of a traditional sensitive information judgment method, sensitive data obtained through primary judgment is judged for the second time, in other words, the misjudgment rate is lowered based on cluster judgment, and the judgment burden of the specialist is relieved.

Description

technical field [0001] The invention relates to the field of data security, in particular to a method for reducing the misjudgment rate of sensitive information. Background technique [0002] The current sensitive information detection methods are mainly based on information retrieval technology. According to the general process of information detection, sensitive information detection research is divided into three types: query expansion technology, document indexing technology and information detection model. [0003] The query expansion technology mainly uses the semantic expansion technology to expand the semantics of the words given by the user through multiple modes to form multiple expanded words for retrieval, so as to improve the recall rate and accuracy of detection. [0004] Document indexing technology extracts data from unstructured and semi-structured documents and reorganizes them so that they can be recognized by computers. [0005] The information detection...
