Abstract:
|
Data swapping can be used by government agencies to protect the confidentiality of publicly released data files. We study the stochastic process generated by data swapping applied to a data file of categorical variables to understand the effect of swapping and to help the original data owners determine which variables to swap and how much to swap. We will discuss utility measures and introduce the idea of measuring distance from the limit, rather than from the original file. In addition, we will introduce a new type of swapping that we propose is superior to current methods.
