PROBLEM TO BE SOLVED: To allow a flexible procedure to obtain anonymization data required by users.SOLUTION: In a personal information anonymization support device, provided are: (1) an anonymization object data take-in unit that takes in anonymization object data; (2) a generalization hierarchy generation unit that generates generalization hierarchy data on the basis of the anonymization object data; (3) a first k-anonymization execution unit that k-anonymizes the anonymization object data using the generalization hierarchy data, and outputs anonymization data as a result of the k-anonymization and incidental information on the k-anonymization; (4) an anonymization map editing unit that displays an anonymization map underlining a value of a sub-identifier used in generation of the k-anonymization data on a screen on the generalization hierarchy data having a tree structure displayed, and receives an editing input with respect to the anonymization map; (5) a second k-anonymization execution unit that k-anonymizes the anonymization object data using the edited anonymization map; (6) a storage device that stores the anonymization object data, the generalization hierarchy data, the k-anonymization data, and the anonymization map.SELECTED DRAWING: Figure 4 |
