An information theoretic approach for privacy metrics
Organizations often need to release microdata without revealing sensitive information. To this scope, data are anonymized and, to assess the quality of the process, various privacy metrics have been proposed, such as k-anonymity, `-diversity, and t-closeness. These metrics are able to capture different aspects of the disclosure risk, imposing minimal requirements on the association of an indivi...
متن کاملAn Information-Theoretic Approach for Privacy Protection in OLAP Systems
We address issues related to the protection of private information in Online Analytical Processing (OLAP) systems, wherea major privacy concern is the adversarial inference of private information from OLAP query answers. Most previous work onprivacy-preserving OLAP focuses on a single aggregate function and/or addresses only exact disclosure, which eliminates fromconsideration an im...
