Abstract (in Japanese) (See Japanese page) 
(in English) Data utilization has privacy invasion risks. Considering such risks, there is a trade-off between anonymity and usefulness of anonymized information.Recently, random sampling combined with anonymization methods is proposed for the usefulness while maintaining anonymity. In this report, we focus on the anonymity of statistical information and combine random sampling with medical statics patient characteristics.As a result, re- garding the usefulness, we can estimate the crosstabulation table used in medical statistics with less than 2 percent error for 10000 samplings. Regarding anonymity, although the raw data cannot be re-identified from the samples, there is a risk of anonymity invasion due to homogeneous attacks like.
