Method Detail

anonymize

public static String[][] anonymize(String[] attributes,
                                   String[][] content)

kAnonymize

public static String[][] kAnonymize(String[][] dataOri,
                                    int k)

This function applies k-anonymization to a dataset

Parameters:

dataOri, - the dataset

k, - the desired k level

Returns:

the anonymized version of the dataset that fullfils k-anonymity

kAnonymize

public static ArrayList<Record> kAnonymize(ArrayList<Record> dataOri,
                                           int k)

kAnonymize_tCloseness

public static String[][] kAnonymize_tCloseness(String[][] dataOri,
                                               int k,
                                               double t)

This function applies k-anonymization + t-closeness to a dataset

Parameters:

dataOri, - the dataset

k, - the desired k level

t, - the desired t closeness

Returns:

the anonymized version of the dataset that fullfils k-anonymity and t-closeness

kAnonymize_tCloseness
