[0037] The present invention is further described below in conjunction with the accompanying drawings. But not limited to the following examples.
[0038] A t-closeness privacy protection method satisfying ε-differential privacy, comprising the following steps:
[0039] Step 1: Preprocess the original data to establish a QIS data table associated with quasi-identifiers and sensitive attributes. The main steps are as follows:
[0040] 1) Establish a correspondence table between the quasi-identifier Qi and the sensitive attribute Si, and each quasi-identifier corresponds to its unique sensitive attribute as an index table.
[0041] 2) Sort the records using sensitive attributes, and generate different regions by taking the value of k, iteratively record the k smallest and largest records.
[0042] 3) Store the acquired records in a new data table in turn to generate the final QIS associated data table.
[0043] The algorithm steps are as follows:
[0044] a) Let D={(Qi,Si)|i...
