Auditing Boolean attributes

We study the problem of auditing databases which support statistical sum queries to protect the security of sensitive information; we focus on the special case in which the sensitive information is Boolean ...
Principles and techniques developed for the security of statistical databases in the case of continuous attributes do not apply here. ...
Evidently, Boolean attributes make the auditing problem much more tricky. ...

We study the computational complexity of auditing finite attributes in databases allowing statistical queries. ...
Given a database that supports statistical queries, the auditing problem is to check whether an attribute can be completely determined or not from a given set of statistical information. ...
To exemplify the use of our results we study the auditing problem for a number of statistical queries (such as max, mean and median), and we completely classify the problem of auditing Boolean attributes ...

Our framework includes a historical data model that supports flexible audit queries, along with a language for retention policies that hide individual attribute values or remove entire tuples from history ...
Under retention policies, the audit history is partially incomplete. We formalize the meaning of audit queries on the protected history, which can include imprecise results. ...
For example, our audit log L S can be joined with T S on the ttime attribute. ...

The auditing problem has also been examined when the private attribute is boolean. Surprisingly, full-disclosure auditing of sum queries over boolean data is coNP-hard. ...

We study the Boolean conjunctive queries under a more detailed scope, where we investigate their counting problem by means of the algebraic approach through Galois theory, taking advantage of Post's lattice ...
This is a generalization of the audit problem for Boolean attributes defined in [KPR03] (see also [KJ03] ), which is particularly interesting in databases supporting statistical queries. ...

To further examine the practicability of auditing interval-based inference, we classify various auditing methods into three categories: exact auditing, optimistic auditing, and pessimistic auditing. ...
Compared with auditing exact inference that is traditionally studied, auditing interval-based inference is more complicated. Existing auditing methods such as audit expert do not apply to this case. ...
[20] recently proved that auditing Boolean attributes is a NP-hard problem. ...
