PROBLEM TO BE SOLVED: To perform an aggregate function arithmetic operation of which the computational complexity is proportional only to the number of data items, while concealing information.;SOLUTION: A secure aggregate function system is comprised of N pieces of secret aggregate function apparatuses and determines a secret distributed totalization result from information ([k1], [v1]), ..., ([kM], [vM]) secretly distributing M pieces of information items (k1, v1), ..., (kM, vM) including a key km and an attribute value vm. The secure aggregate function system includes initialization means and coupling arithmetic operation means. The initialization means sets the M pieces of data items z1, ..., zM like zm=vm and generates information ([k1], [z1]), ..., ([kM], [zM]). The coupling arithmetic operation means performs such coupling processing for setting zj=zi(+)zj, zi=(0) if a key ki and a key kj are equal and for setting zj=zj, zi=zi if not equal on all the information having equal keys through secret computation.;COPYRIGHT: (C)2012,JPO&INPIT
