1. An apparatus, comprising:
a fake transaction inserter that generates fake transactions of a predetermined number each having a predetermined length and inserts the fake transactions between a plurality of transactions comprised in an original data set to generate a first virtual data set; and a distortion transaction generator that protects the privacy of the original data set by generating a second virtual data set by converting data of the transaction of the first virtual data set with a predetermined probability, wherein the distortion transaction generator generates the transaction of the second virtual data set by using a result of an exclusive OR function having the conversion variable and the transaction of the first virtual data set corresponding to the conversion variable as an independent variables.
