In order to provide an anonymization technology which, in a data set wherein unit value attributes and set value attributes are mixed, processes the set value attributes whereto taxonomies have not been assigned, in coexistence and scalably with the other attributes, this information processing device comprises: a cluster information acquisition means for acquiring, from a cluster which is a set of records which include attribute values, information which represents a cluster which is a set of records in an anonymized state whereupon at least a portion of the attribute values have been removed, among set value attributes included in the records which may include one or a plurality of values, such that the cluster satisfies a prescribed anonymity; and a set value attribute specialization means for disclosing at least a portion of the attribute values from the removed attribute values among the set value attributes of the records which are included in the cluster which the cluster acquisition means has acquired, and, on the basis of the disclosed attribute values, segmenting the cluster into the cluster which satisfies the prescribed anonymity. |
