Information processing apparatus for verifying anonymity and anonymity verification method

摘要

The present invention provides an information processing apparatus capable of reducing the calculation cost of anonymity verification in anonymization when multidimensional data is to be anonymized. The information processing apparatus includes means for generating information indicating a correspondence between a record included in the data set and a class for identifying a unique combination of the semi-identifier attribute values, and means for, based on the class indicated in the information, Means for verifying the anonymity of each record and means for updating and outputting the information so that the record not satisfying the anonymity can be identified based on the result of verifying the anonymity .
