specific Embodiment 1

[0130] The field-level financial data in the basic financial data is marked according to the security scene label list, and the table-level financial data is marked on the basis of marking each table field of the table separately.

[0131] 1) Field-level financial data security level labeling. For ease of description, the following field names refer to field-level financial data names.

[0132] (1) Predetermining a security scene label list, the security scene label list includes multiple labels and their corresponding security levels, wherein the labels in the security scene label list are standardized field names (ie, canonical names).

[0133] (2) Perform corpus cleaning processes such as word segmentation and removal of stop words for each field name.

[0134] (3) Compare the text similarity between the name of each field to be analyzed after cleaning and the labels in the security scene label list one by one, and obtain the label with the highest degree of consistency wit...

specific Embodiment 2

[0140] When registering financial data of processing and management metadata (such as processing financial data and management financial data), the security level of the financial data of processing and management metadata is first marked manually. The security level of the financial data of the processing and management metadata to be analyzed is automatically marked by comparing the following two levels of similarity.

[0141] The calculation method of text similarity is the same as in the case of field-type financial data. At the same time, a similarity threshold needs to be set in the similarity comparison between the two levels. In the screening described below, the similarity is required to be higher than a given threshold. Specifically, the security level labeling process includes:

[0142] (1) First compare the names with the marked processing management metadata financial data, and filter out the marked processing management metadata with high similarity in names (tha...

Abstract

This paper provides a sensitive data security level labeling method and device, wherein the method includes: determining the data type of the sensitive data to be analyzed, wherein the data type includes basic metadata and processing management metadata; according to the basic metadata According to the list of sensitive data to be analyzed and security scene labels, determine the security level of the sensitive data to be analyzed in the basic metadata category; according to the sensitive data to be analyzed in the processing management metadata category and the sensitive data marked with security levels in the processing management metadata category, determine the security level of the processing management metadata category. Manage the security level of metadata class sensitive data to be analyzed. This example can mark the security level of sensitive data in different formats and contents on one system, so as to realize the efficient classification of sensitive data security level, and finally implement the data security requirements of different levels. This article has a wide application range and reasonable security level classification The advantages.

Description

technical field [0001] This paper relates to the field of sensitive data management, and in particular, to a method and device for marking the security level of sensitive data. Background technique [0002] With the advancement of digitalization, financial enterprises such as banks will generate a large amount of sensitive data in various links such as business development, management and external introduction, and the scale of data assets has increased dramatically. At the same time, regulatory agencies have become more and more stringent on the security of sensitive data. In this context, it is imperative for enterprises to strengthen the security management of sensitive data. [0003] The existing technology mainly uses the regular matching method of sensitive data table fields to determine the security level. Specifically, most of them are based on the specific data content of the field to identify the sensitive field, and then implement the data security management requ...
