Security and Disclosure for Statistical Information
|
Abstract:
Standard security considerations arise during the collection of information for statistical purposes, and statistical organizations need to ensure that information supplied by individual people or organizations is not revealed to unauthorized view. For this they expect to use the standard security mechanisms developed in other domains. However, the purpose of a statistical inquiry is to reveal information—to provide access, not restrict it. The objective of Statistical Disclosure Control is to control the risk that information about specific individuals can be extracted from amongst statistical summary results. This paper will review the issues and outline some of the solutions that are being used.
