Embodiment 1

[0040] Embodiment 1 of the present invention proposes a method for qualitatively analyzing an anonymous model. like figure 1 As shown, the method of Embodiment 1 of the present invention includes the following steps:

[0041] Step S1: According to the preset specific application scenario, determine the visible information and hidden information in the application scenario.

[0042] According to the actual application scenario, analyze the importance of information, and determine the need for visible information and hidden information, that is, the input and output of the anonymous model. In Embodiment 1 of the present invention, the set of hidden information is called an anonymous event set A, and any value of any of them is A. The visible information is called a visible event set O, any of which takes a value of o, and each hidden information A corresponds to a visible information o.

[0043] The above-mentioned visible information is the information that can be obtained b...

Embodiment 2

[0071] Embodiment 2 of the present invention proposes a device for qualitatively analyzing anonymous models. Such as image 3 As shown, the device of Embodiment 2 of the present invention includes:

[0072] An information determination module 10, configured to determine visible information and hidden information according to preset application scenarios;

[0073] The selection model module 20 is used to traverse the preset anonymous model set and select an anonymous model whose anonymity loss degree is within a preset range; when the anonymity loss degree is the visible information input to the anonymous model set in the anonymous model set, The output is the probability of the hidden information.

[0074] Such as Figure 4 As shown, the selection model module 20 includes:

[0075] An acquisition unit 21, configured to acquire an anonymous model from the anonymous model set;

[0076] A computing unit 22, configured to input the visible information into the anonymous model...

Abstract

The invention belongs to the field of data mining and provides a method and device for qualitatively analyzing an anonymity model. The methods includes the steps of determining visible information and concealed information according to a preset application scenario, traversing a preset anonymity model set, and selecting an anonymity model with an anonymity loss degree in a preset range, wherein the anonymity loss degree is a probability that the visible information is output as the concealed information when the visible information is input into the anonymity model in the anonymity model set. The method and device for qualitatively analyzing the anonymity model can evaluate the anonymity model.

Description

technical field [0001] The invention belongs to the field of data mining, in particular to a method and device for qualitatively analyzing an anonymous model. Background technique [0002] Data mining refers to the non-trivial process of revealing implicit, previously unknown and potentially valuable information from a large amount of data in a database. In recent years, data mining has attracted great attention from the information industry. The main reason is that there is a large amount of data, which can be widely used, and it is urgent to convert these data into useful information and knowledge. The acquired information and knowledge can be widely used in various applications, including business management, production control, market analysis, engineering design and scientific exploration, etc. [0003] The rapid development of data mining is accompanied by the disclosure of information, especially the disclosure of personal privacy information. In order to solve this...
