Embodiment Construction

[0021] Various embodiments are proposed below for detailed description. However, the embodiments are only used as examples for illustration and will not limit the scope of protection of the present invention. In addition, some components are omitted from the drawings in the embodiments to clearly show the technical characteristics of the present invention. The same reference numbers will be used throughout the drawings to refer to the same or similar components.

[0022] The rapid development of the network makes information sharing easier and faster. However, data sharing raises user privacy concerns. Malicious users can obtain the user's real life situation by analyzing the data and the correlation between the data, which may cause the user's real loss.

[0023] k-anonymity (k-anonymity) technology is a mechanism to protect data privacy. The k-anonymity technology de-identifies the data before the data is released, so that at least k-1 data in the data cannot be distingui...

Abstract

The invention provides a data de-identification method, a data de-identification device and a non-volatile computer-readable storage medium for executing the data de-identification method. The data de-identification method includes: obtaining original data, wherein the original data includes an identity column, a condition field, and a record field, obtaining situational conditions according to the condition field, and obtaining multiple identification data and situational conditions according to the identity column records, from Acquiring context segment sequences corresponding to each identification data that meet the context conditions from the original data, obtaining sequence data according to the identification data and the context segment sequences corresponding to the identification data, and adjusting the sequence data to obtain de-identified data.

Description

technical field [0001] The invention relates to a data de-identification method, a data de-identification device and a non-volatile computer-readable storage medium for executing the data de-identification method. Background technique [0002] Recently, data application has become a trend. For enterprises and governments, how to use data to discover value, solve problems, and then improve work processes or revitalize administrative services is one of the goals of effective data application. [0003] However, the promotion of big data (big data) and open data (open data) has created concerns about the infringement of personal privacy. Therefore, it is necessary to carry out data de-identification (data de-identification) on the data released and disclosed, so that it is impossible to A specific individual is directly or indirectly identifiable from the manner in which the de-identified data is presented. [0004] Therefore, how to make the personal data in the data released ...
