Raw microdata (i.e.\u2009individual records) are grouped into small aggregates prior to publication. With fixed-size groups, each aggregate contains k records to prevent disclosure of individual information. Individual ranking is a usual criterion to reduce multivariate microaggregation to univariate case: the idea is to perform microaggregation independently for each variable in the record. Using distributional assumptions, we show in this paper how to find interval estimates for the original data based on the microaggregated data. Such intervals can be considerably narrower than intervals resulting from subtraction of means, and can be useful to detect lack of security in a microaggregated data set. Analytical arguments given in this paper confirm recent empirical results about the unsafety of individual ranking microaggregation.<\/jats:p>","DOI":"10.1142\/s0218488502001594","type":"journal-article","created":{"date-parts":[[2002,11,18]],"date-time":"2002-11-18T10:28:06Z","timestamp":1037615286000},"page":"477-491","source":"Crossref","is-referenced-by-count":23,"title":["ON THE SECURITY OF MICROAGGREGATION WITH INDIVIDUAL RANKING: ANALYTICAL ATTACKS"],"prefix":"10.1142","volume":"10","author":[{"given":"JOSEP","family":"DOMINGO-FERRER","sequence":"first","affiliation":[{"name":"Universitat Rovira i Virgili, Dept. of Computer Eng. and Maths, Av.
