Most of them are distributed free mainly because of the lack of the adequate billing scheme; the currently deployed billing schemes for content are inadequate for UGC, of which creator and quality are much more diverce than content created by professional creators, and accordingly the users have the risk to pay too much for crude or useless content. This risk may lead the UGC market to a lemon market, where most merchandises (i.e. UGC) in the market becomes inferior in quality. This paper discusses measures to address this problem and proposes a solution introducing a smartcard-based micro-billing scheme for UGC, by which a user pays for content according to how much she or he plays it, and thus the risk of the quality of content is mitigated. This paper also shows that the proposed scheme can be implemented securely and feasibly by using current smartcards.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"727","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"716","bibliographicIssueDates":{"bibliographicIssueDate":"2010-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"51"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:28:30.158523+00:00","updated":"2025-01-22T00:09:35.819610+00:00"}
