Statistical Disclosure Risk: An Overview

Abstract

National statistical institutes (NIS) publish a wide range of trusted, high quality statistical outputs. To achieve their objective of supplying society with rich statistical information these outputs are as detailed as possible. However, these objectives conflict with the obligation NSI that have to protect the confidentiality of the information provided by the respondents. Statistical disclosure control or statistical disclosure limitation seeks to protect statistical data in such a way that they can be released without giving away confidential information that can be linked to specific individuals or entities. In this paper we give an overview for the most important concepts of the statistical disclosure control tools.
