In this final chapter we consider the SDC techniques adding noise, rounding and source data perturbation (SDP). Adding noise perturbs the cell values in a table by adding random values to them. The random values are generated according to a prescribed probability distribution. “Rounding” in fact refers not to a particular SDC-technique but rather to a class of SDC-techniques. Each of these SDC-techniques has its own advantages and disadvantages.
