Problems solved by technology

Although at least K pieces of data can be locked during the attack, multiple pieces of data in the equivalence class contain the same sensitive attribute value, which makes it easy for the attacker to determine the sensitive attribute value of the target object, resulting in privacy leakage and reducing data security.

Abstract

The invention provides a data processing method and device. The method comprises the steps of determining one piece of data serving as a centroid of a cluster in a to-be-processed data set; selectinga first preset number of data from the remaining data according to the distance between the remaining data in the to-be-processed data set and the centroid, and adding the first preset number of datainto the cluster; determining the number of sensitive attribute values of the sensitive attribute fields in the cluster; if the number is smaller than the preset number, selecting data from the data which is not added into the cluster according to the distance between the data which is not added into the cluster in the to-be-processed data set and the centroid, and continuing until the number is equal to or larger than the preset number, so that the number of different sensitive attribute values of the same sensitive attribute field in the cluster is at least a preset number. In the attack process, the same sensitive attribute field in the cluster at least has a preset number of sensitive attribute values, so that the sensitive attribute values cannot be easily obtained according to a plurality of sensitive attribute values of the sensitive attribute field; the data security is improved, and the probability of privacy disclosure is reduced.

Description

technical field [0001] The disclosure belongs to the technical field of data processing, and in particular relates to a data processing method and device. Background technique [0002] The original data collected in the production process of the enterprise contains private information, such as user identity information and other personal privacy information related to user identity information, etc. If the original data containing private information is released, privacy leakage will occur. In order to reduce privacy leakage, the original data is desensitized by at least one of the methods of anonymizing the original data, exchanging it, and adding noise data. Currently, the commonly used desensitization method among these three methods is to desensitize the original data. Referred to as data anonymization processing, data anonymization processing desensitizes at least one of the attribute fields and sensitive attribute values ​​in the original data, so that the attribute fi...
