Abstract
Provided is a technique for performing statistical processing such as processing for obtaining parameters of logistic regression analysis faster than before. A secure statistical processing system includes a cross tabulation table computing devicethat performs secure computation on a cross tabulation table in which frequencies are in plain texts while keeping each record concealed; and a statistical processing devicethat performs predetermined statistical processing using the cross tabulation table in which frequencies are in plain texts. The cross tabulation table computing devicemay include a plurality of secure computation devicesN that perform secure computation on a cross tabulation table in which frequencies are fragments subjected to secret sharing while keeping each record concealed, and a management devicethat restores the fragments to compute the cross tabulation table in which frequencies are in plain texts.
