Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes architecture of information recommendation system based on privacy preserving user history by coordination with between two service providers for better recommendation results appropriate for user status. The two providers identify each user employing the single sign on mechanism through an ID provider. One of the service providers calculates matching rates between user and holding items using encrypted user history sent from the other service provider. The matching rates are returned to the service provider for decryption, then obtained is the order of estimated rate value by content base filtering. The calculation protocol mentioned above is illustrated exemplified by a menu recommendation service. An implementation example of the system is shown using an open source content management system.
