Abstract

In an example, a query on a plurality of previously submitted confidential data values for a first cohort having one or more attributes is obtained, and a level in a hierarchy corresponding to an attribute type for the attribute is determined for each attribute. One or more additional cohorts corresponding to different combinations of generalizations of the one or more attributes up one or more levels in each hierarchy corresponding to an attribute type for each attribute are formed. For each cohort, a confidence score and a granularity score are calculated, and then a cohort score is calculated based on a weighted combination of the confidence score and the granularity score. A statistical function is performed on previously submitted confidential data values for a cohort having the highest cohort score, and a response to the query including a result from the statistical function is formed.
