Embodiment Construction
[0051] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0052] The present invention provides an anonymous method for missing data. The method is based on a distance calculation method based on information entropy, and performs anonymous processing for missing data types, including:
[0053] ST1: Set the clustering parameter k, the clustering parameter k indicates that in multiple groups formed by clustering, each group includes no less than k data records;
[0054] ST2: Set l-diversity model parameter l; the parameter l indicates that each group includes not less than l different quasi-identification attribute types.
[0055]ST3: According to the similarity judgment value of the data records in the data set, l-diversity model parameters and clustering parameters, cluster all the data records in the data set, divide the data set into multiple clusters, and obtain multiple clustered data s...
