Zusammenfassung:The inaccessible set consists of those elements in a statistical database which cannot be compromised if queries of a certain fixed type are used. We define the size of the inaccessible set as a measure of the security of statistical databases; this measure has the property that it reflects changes in the type of the queries in a very direct way. We then derive several of these measures for various types of queries.
