In the previous authentication systems based on keystroke intervals, user was more exactly discriminated by the speed of each keystroke in addition to the user name and the password. However, they still have a problem that an authentication might be difficult when the speed of each keystroke was similar to the other person's. We solve this problem by making a rhythm keystroke to each user at the time of the authentication.","subitem_description_type":"Abstract"}]},"item_2_description_40":{"attribute_name":"資源タイプ(DSpace)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_2_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"ここに掲載した著作物の利用に関する注意 本著作物の著作権は情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。\n\\nNotice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
