Examples of Easy-to-implement, Widely Used Methods of Masking for which Analytic Properties are not Justified
Examples of Easy-to-implement, Widely Used Methods of Masking for which Analytic Properties are not Justified
RRS2007-21
Abstract
This paper provides examples that illustrate the severe analytic distortions of many widely used masking methods that have been in use for a number of years. The masking methods are intended to reduce or eliminate re-identification risk in public-use files. Although the masking methods yield files that do not allow reproduction of the analytic properties of original, confidential files, in a number of situations they sometimes allow small amounts of re-identification using elementary methods and widely available software.
