Information Loss in Partitioned Statistical Databases
Klinische Dokumentation, Universitat Ulm, Eythstr. 2, Ulm, Germany
Partitioning is an interesting approach to protecting statistical databases. It is highly secure and can, among other things, take into account the dynamics of a statistical database. This paper shows that partitioning often will either result in high information loss or in a serious distortion of important statistical functions. In order to make partitioning practical, these difficulties must be overcome.
