Abstract: System and method for k-anonymization with a target k-value according to certain embodiments. For example, a method includes: receiving an input dataset; receiving a k-value, the k-value being a positive integer; receiving one or more quasi-identifiers corresponding to one or more data fields in the input dataset; receiving a data suppression strategy including one or more transformation steps, at least one transformation step of the one or more transformation steps associated with at least one quasi-identifier of one or more one or more quasi-identifiers; and applying the one or more transformation steps to the input dataset to generate a suppressed dataset including at least one suppressed data field corresponding to the at least one data field; checking an anonymity value of each data record of a plurality of data records in the suppressed dataset; selecting a subset of the suppressed dataset from the suppressed dataset.
