Reverse Mapping To Preserve The Marginal Distributions Of Attributes In Masked Microdata
PRIVACY IN STATISTICAL DATABASES, PSD 2014(2014)
摘要
In this paper we describe a new procedure that is capable of ensuring that the marginal distributions of attributes in microdata masked with a masking mechanism end up being the same as the marginal distributions of attributes in the original data. We illustrate the application of the new procedure using several commonly used masking mechanisms.
