Results from the case study for the Adult-TN dataset. (a) A comparison of the 10-anonymization frontier, Safe Harbor policy, and the Sublattice Heuristic Search (SHS) frontier in the R-U space. The policies between the 215th and the 292nd on the SHS frontier (in the rectangle) dominate Safe Harbor. (b)–(d) provide a comparison of Safe Harbor and two dominating policies −232 and 292. (b) A comparison of the generalization rules for race and gender attributes. (c) A comparison of the age generalization rule. The x-axis corresponds to the original age, while the y-axis corresponds to the median of the generalized age interval. (d) A comparison of the ZIP generalization rule. The x-axis corresponds to the original ZIP, while the y-axis corresponds to the median of the ZIP interval. The ZIP codes are represented as an ordinal index, the translation for which can be found in the Supplementary Appendix online.
