Abstract
A system and method for objective quantification and mitigation of privacy-risk of a dataset is disclosed. The system and method include an input-output (IO) interface for receiving at least one input dataset, on at least one of which a measurement of the risk is to be performed, and a configuration file governing the anonymization; a scoring engine including: a uniqueness sub-engine for determining uniqueness scores at data and data-subject level across both individual columns and combinations of columns; a similarity sub-engine that calculates the overlap, reproducibility and similarity by comparing all columns and subsets of columns between at least two datasets, where one dataset is the original version and the other one is transformed, modified, anonymized or synthetic version of original dataset; a statistical sub-engine that calculates statistics that are an indication of privacy-risks and re-identification risks; a contextual sub-engine for quantifying contextual factors by considering weighted approaches and producing a single context-centric score; and a recommendation engine identifying mitigating measures to reduce the privacy-risks by taking in to account the factors t…
