Embodiment Construction
[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0035] figure 1 A schematic flowchart of a method for data generalization based on Skyline provided by an embodiment of the present invention includes steps S101 to S103.
[0036] Step S101, according to the data release privacy protection standard 10-anonymous processing of the data table, the risk amount R of the re-identification of the strategy is recorded as a threshold value T, and the strategy space is determined according to the range of the quasi-identifier attribute and the threshold value T. {S, (R, U)}, U is the information loss of the strategy, and the R value of the strategy...
