Abstract

The invention provides a sensitive attribute data processing method and system. The method comprises the steps of obtaining a user data set; obtaining a plurality of sensitive attribute sub-data setsbased on the quasi-identifier attributes and the sensitive attributes; dividing the plurality of sensitive attribute sub-data sets into a plurality of sensitive attribute data record groups; determining a first sensitive attribute data record group conforming to the composite multi-sensitive attribute L-diversity, and determining a second sensitive attribute data record group not conforming to thecomposite multi-sensitive attribute L-diversity; adding the data in the second sensitive attribute data record group to the first sensitive attribute data record group under the condition of not destroying the L-diversity of the composite multi-sensitive attribute; and anonymizing all the first sensitive attribute data record groups to obtain multiple groups of anonymous groups, performing randomsorting, and publishing a random sorting result. The corresponding relations between the quasi-identifier attribute and the sensitive attribute are disorganized, so that the private information of the user is prevented from being speculated according to the user data, and the usability and the security of the personal information are ensured.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and system for processing sensitive attribute data. Background technique [0002] With the rapid development of the information field and the network field, data has shown explosive growth. Massive amounts of personal information are released every day, such as census data, personal consumption data, and medical data that contain personal information. Government departments and commercial organizations will analyze the collected personal information for better social management and business decision-making. [0003] In the process of publishing personal information, sensitive attribute data in personal information may be leaked, causing a great negative impact on the leaked personnel. Therefore, when publishing personal information, the identity-related attribute data in the personal information will be deleted to achieve the purpose of protecting personal priv...
