Rounding
Definition
Microdata rounding is a family of masking methods for statistical disclosure control of numerical microdata; a similar principle can be used to protect tabular data. Rounding replaces original values of attributes with rounded values. For a given attribute Xi, rounded values are chosen among a set of rounding points defining a rounding set (often the multiples of a given base value).
