What Is This Project?

This project examines sanitization, or the suppression of information in documents provided to others. The data is suppressed because it is deemed too sensitive for others to see, possibly because the data contains personal information, the data might show attackers weaknesses which they could exploit to steal information or material goods, or cause damage to, a company, organization, or government agency, or because the data is protected by law.

This project considers the problem of sanitization to be reconciling privacy requirements with auditing requirements, and if they are irreconcilable, providing the conflicting requirements to both parties so they can determine the effects of trading off requirements among the two sets. It also considers the mathematics of sanitization, to explore the conditions under which "perfect sanitization" (in which an adversary cannot reconstruct unsanitized data from sanitized data) can occur.

The significance of this work is to view sanitization as the balancing of two different perspectives, rather than as an absolute requirement from either perspective. Its broader impact is to derive a more rigorous approach to sanitization, and to be able to quantify the degree to which sanitization is done.
