Obfuscation of Discrete Data

Abstract: Data obfuscation deals with the problem of masking a data-set in such a way that the utility of the data is maximized while minimizing the risk of the disclosure of sensitive information. To protect data we address some ways that may as well retain its statistical uses to some extent. One such way is to mask a data with additive noise and revert to certain desired parameters of the original distribution from the knowledge of the noise distribution and masked data. In this project, we discuss the estimation of any desired quantile and range of a quantitative data set masked with additive noise.
