PROBLEM TO BE SOLVED: To provide a technology for anonymizing object data by processing the object data on the basis of the value after abstraction.SOLUTION: Object data including a plurality of items associated with an individual is received, abstraction candidate data is generated instead of a word obtained by abstracting a word being values of the items in the object data, the value of a word included in the abstraction candidate data is received, the value of the abstraction candidate data is calculated on the basis of the value of the word included in the abstraction candidate data, examination is performed on condition that a combination of the values of the items corresponding to one individual of the abstraction candidate data is not single in the abstraction candidate data, and abstraction candidate data is selected on the basis of the value of abstraction candidate data satisfying the condition of the examination. |
