PROBLEM TO BE SOLVED: To improve anonymization processing efficiency by executing anonymization processing by division number with a high possibility of satisfying anonymity on the basis of a reduction coefficient.;SOLUTION: A reduction coefficient calculation device performs: acquiring anonymity information which is anonymized personal information; determining division number by dividing for each word type which an attribution composing the anonymity information may have; determining minimum appearance number of each word; and determining a reduction coefficient which shows decrement of the minimum appearance number when the division number is increased on the basis of a combination of the plurality of division numbers of different division numbers and the minimum appearance number.;COPYRIGHT: (C)2016,JPO&INPIT
