Report On Statistical Disclosure And Disclosure Avoidance Techniques

"The purpose of this paper is to describe the disclosure avoidance procedures of the Canadian Censuses of Population and of Agriculture. The two censuses present different disclosure issues, and the approaches adopted are quite different. In the case of the Census of Population, the main emphasis is on disclosures that would result from publication of very small frequencies while for the Census of Agriculture, with tabulations of aggregate magnitude data (e.g. expenditures), it is not only small numbers of respondents that cause a problem but also the amounts contributed to totals by individuals. The main emphasis of this paper is on the procedures to be used for the 1986 Censuses; however, these are put in perspective by a comparison to techniques used in earlier censuses and a description of user reaction to the procedures"--Page 1.

This book constitutes the refereed proceedings of the International Workshop on Privacy in Statistical Databases, PSD 2004, held in June 2004 in Barcelona, Spain as the final conference of the European IST Project Computational Aspects of Statistical Confidentiality. The 29 revised full papers presented were carefully reviewed and selected from 44 submissions. The papers are organized in topical sections on foundations of tabular protection, methods for tabular protection, masking for microdata protection, risks in microdata protection, synthetic data, and software and case studies.
