Embodiment Construction
[0038] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0039] In order to shorten the execution time and improve the accuracy of information, the embodiment of the present invention provides an improved K-anonymity method. The embodiment of the present invention is based on the K-anonymity algorithm for de-identifying private data. The processing is mainly to further optimize the generalization lattice after obtaining the optimal node, as described below for details:
[0040] 101: Select a quasi-identifier according to the original data set, determine the generalization method by the quasi-identifier, and establish an initial generalization lattice corresponding to the generalization method;
[0041] Among them, the K-min set is saved after traversing the initial generalization lattice. s...
