Disclosure Analysis and Control in Statistical Databases
Disclosure analysis and control are critical to protect sensitive information in statistical databases when some statistical moments are released. A generic question in disclosure analysis is whether a data snooper can deduce any sensitive information from available statistical moments. To address t...

A generic question in disclosure analysis is whether a data snooper can deduce any sensitive information from available statistical moments. To address this question, we consider various types of possible disclosure based on the exact bounds that a snooper can infer about any protected moments from available statistical moments. We focus on protecting static moments in two-dimensional tables and obtain the following results. For each type of disclosure, we reveal the distribution patterns of protected moments that are subject to disclosure.

Disclosure analysis and control are critical to protect sensitive information in statistical databases when some statistical moments are released.

We focus on protecting static moments in two-dimensional tables and obtain the following results. For each type of disclosure, we reveal the distribution patterns of protected moments that are subject to disclosure.
