Abstract

We propose a method to protect sensitive information in a two-dimensional statistical table based on the suppression of certain marginal cells. A sensitive cell set is considered unprotected if its exact value can be computed from the values of nonsensitive cells and unsuppressed marginal cells. We provide efficient algorithms to solve the following problems: deciding whether the sensitive cell sets are protected, identifying and evaluating all unprotected cell sets, suppressing the fewest marginal cells to protect all the sensitive cells.
