[Problem] To propose an anonymized data providing device and method whereby an anonymized data set matching the need of a data user can be provided. [Solution] A data user sets an allowable significance level of a desired statistical amount of a desired attribute regarding a desired data set as a user requirement. An anonymization process is executed a plurality of times for the data set selected by the data user. With respect to each of a plurality of anonymized data sets obtained by the plurality of anonymization process, the statistical amount set by the data user is respectively calculated, the calculated statistical amount of each of the anonymized data sets and the statistical amount of the data set of original data are compared, the anonymized data set of which a difference in the statistical amount satisfies the allowable significance level set by the data user is selected as an anonymized data set satisfying the user requirement, and the selected anonymized data set is provided to the data user. |
