| Abstract(in English) | Collaborative filtering recommends unknown contents to a user based on the past behavior or review of the user and is usually used for recommender systems. Personal information, such as user's actions, are used to determine the information which is recommended to a user and are stored in a service provider. However, users usually do not want to disclose the data to third parties. In this paper, we propose a privacy-preserving recommendation protocol using one of fully homomorphic encryption schemes. Performance analyses of the protocol are performed. |
