Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a user privacy preserving method cooperating two kinds of providers. Users’ acquisition records which are privacy information and consist of a user-Id and bought items are divided and held in the IdP and SPs. The IdP provides SPs temporal Ids linked to the original user-Ids so as to reconstruct encrypted acquisition records. An item similarity table used in collaborative filtering for information recommendation can be calculated by cooperation of the Idp and SPs.
