Split leverage: attacking the confidentiality of linked databases by partitioning

Tapan Rai, Joanne L. Hall

Abstract


This article considers the risk of disclosure in linked databases when statistical analysis of micro-data is permitted. The risk of disclosure needs to be balanced against the utility of the linked data. The current work specifically considers the disclosure risks in permitting regression analysis to be performed on linked data. A new attack based on partitioning of the database is presented.
