Cardinality-based inference control in OLAP systems

Nan Zhang, Wei Zhao, Jianer Chen
2004 Proceedings of the 7th ACM international workshop on Data warehousing and OLAP - DOLAP '04  
Compared to previous approaches in sum-only data cubes, our new approach has a more general framework (applies to MIN, MAX and SUM) and is more effective.  ...  The goal of inference controls is to prevent exact values of sensitive data from being inferred through answers to online analytical processing (OLAP) queries.  ...  To copy otherwise, to republish, to post on servers or to redistribute to lists, requires prior specific permission and/or a fee.
