These devices are basically fixed and assumed to use in certain place. Therefore, It is difficult to carry them. In this paper, we propose a method to make a vision based signature authentication system portable. We use fingertip as input device and make signature on the top board of the table. By recording signature movie using a mobile device and processing it at cloud , portable system is realized. We tried two types of kernels, trained with a radial basis function (RBF) and a linear function, for a SVM (Support Vector Machine) classifier to detect a fingertip. We confirmed classifier trained with liner kernel is 2.7 times faster and has nearly same prediction precision to the RBF one.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告ユビキタスコンピューティングシステム(UBI)"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-02-28","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8","bibliographicVolumeNumber":"2011-UBI-29"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":72951,"links":{}}
