These services can be enriched and personahzed by using viewers' personal information such as viewing history. This, however, requires viewers to share their viewing history with service providers, hence raising privacy concerns. Using attribute-based encryption (ABE) one can empower viewers to share their viewing history with service providers who satisfy certain criteria (e.g. have well-established reputation). ABE systems require computation that may not be affordable by less resourceful client. In [13], we proposed an outsourcing scheme of ABE encryption to reduce this computation. Our work is the first to consider security against a malicious cloud server who does not follow the protocol and may collude with other entities in the system. In this paper, we implement our scheme and show its effectiveness.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告セキュリティ心理学とトラスト（SPT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2016-07-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"22","bibliographicVolumeNumber":"2016-SPT-19"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":168191,"links":{}}
