Resum
Minimum distance controlled tabular adjustment (CTA) is an emerging perturbative method of statistical disclosure control for tabular data. The goal of CTA is to find the closest safe table to some original tabular data with sensitive information. Closeness is usually measured by l1 or l2 distances. Distance l1 provides solutions with a smaller l0 norm than l2 (i.e., with a lesser number of changes with respect to the original table). However the optimization problem formulated with l2 requires ...
