Embodiment 2

[0049] In this embodiment, the database privacy measurement; the privacy protection technology needs to take data availability into consideration while protecting privacy. Database privacy protection technology is usually measured from the following two aspects.

[0050] First, the degree of privacy protection; the degree of privacy protection is usually reflected by the disclosure risk of publishing data. The smaller the risk of disclosure, the higher the degree of privacy protection.

[0051] Second, data availability; data availability is a measure of the quality of published data, which can reflect the information loss of data processed by privacy protection technology: the higher the data defect, the more information loss, and the lower the data utilization rate. The specific metrics include: the degree of information loss, the similarity between the reconstructed data and the original data, etc.

[0052] In this embodiment, data privacy measurement; data privacy disclo...

Abstract

The invention belongs to the technical field of data set privacy protection, particularly relates to a data set privacy degree measurement method, and provides the following scheme aiming at the problems that no proper technical means is used for measuring the protection degree of data set privacy and the security of the data set privacy cannot be confirmed in the prior art, and the method comprises the following important steps: S1, performing data collection; s2, establishing a field privacy degree model; s3, identifying the privacy degree of the field; s4, identifying a data set; and S5, performing data privacy processing and scoring, wherein a data provider in the S2 maintains a field library, field names which can appear in each data set are collected, and a dynamic privacy degree score of each field name is defined according to the privacy degree of the field. According to the invention, the data privacy can be quickly and effectively measured, the privacy measurement efficiency and effect are improved through analysis from multiple aspects, and the privacy safety can be accurately confirmed.

Description

technical field [0001] The invention relates to the technical field of data set privacy protection, in particular to a method for measuring the privacy degree of a data set. Background technique [0002] With the development of society, information and data are gradually popularized on the Internet. Information and data are very important. Due to the psychology of curiosity or the drive of interests, many malicious attackers are still coveting the privacy of others. The rapid development of the Internet of Things, on the one hand, has prompted a large number of Private information is stored on the network, which provides abundant potential targets for malicious attackers; It is far from enough to protect privacy by laws and regulations. It is necessary to prevent malicious users from stealing user privacy technically. [0003] In the prior art, there is no suitable technical means to measure the protection degree of data set privacy, and it is impossible to confirm the secu...
