FF-Anonymity: When Quasi-Identifiers Are Missing
Existing approaches on privacy-preserving data publishing rely on the assumption that data can be divided into quasi-identifier attributes (QI) and sensitive attribute (SA). This assumption does not hold when an attribute has both sensitive values and identifying values, which is typically the case. In this paper, we study how such attributes would impact the privacy model and data anonymization. We identify a new form of attacks, called ”freeform attacks”, that occur on such data without explicit QI attributes and SA attributes. We present a framework for modeling identifying/sensitive information at the value level, define a problem to eliminate freeform attacks, and outline an efficient solution.
