Field Detail

OUTPUT_FORMAT_GENVALS

public static final int OUTPUT_FORMAT_GENVALS

Outputs anonymized records in the same format as the input records, replacing quasi-identifier attribute values with their generalizations

OUTPUT_FORMAT_GENVALSDIST

public static final int OUTPUT_FORMAT_GENVALSDIST

Outputs anonymized records in the same format as the input records, replacing quasi-identifier attribute values with their generalization and additional information describing the distribution of values within each equivalence class.

OUTPUT_FORMAT_ANATOMY

public static final int OUTPUT_FORMAT_ANATOMY

Outputs anonymized records in anatomized form (i.e., output two tables where the first one QIT contains quasi-identifier values and the second table ST contains sensitive values and all other attributes. The two tables can be joined over the field EID (added as the first column to both) representing the equivalence ID. Among these tables, QIT is written to a file named outputFilename + "QIT" and ST is written to a file named outputFilename + "ST".
